Jonathon Wright

Hello and welcome to the show. Today, I’ve got a very special guest who’s got some amazing tech skills that you could have really not want to miss out on. He’s a principal software developer in tests. So we’re going to be finding out how he’s been establishing some of the latest capabilities within QA and testing. So, welcome to the show. 

Arun Kumar

Thanks. Thanks. Jonathon. 

Jonathon Wright

Do you want to just give us a bit of intro about, you know, your details? Know, the best way to get contacts with you. And you know, also talk a little bit about, you know, where you started. 

Arun Kumar

Yes, sure. So I basically started my career in IT back in 2011 and I basically graduated from college and I was like testing was like a second citizen for me in those days. And I thought that I will be a developer. So I got there in development. And then somehow my manager asked, you know what, I comment we’ve got some projects, nice projects in QA. Do you want to join QA? So initially I said, no, I don’t like in our testing space. I want to be a developer but then somehow she convinced me that she’s like, OK. This is not a traditional QA. You would be like a white box tester, back in 2011. And then she basically got me there. I said, okay white box tester. So what do you mean by that? She’s like, you’ll be writing a unit test. You’ll be basically dealing more code than doing more and process stuff. So I started my journey in 2011. I started working, as I said, as white box QA and I started working for TicketMaster back in the day. And we were basically building REST APIs for them, you know, following scrum and agile.  So for me, to be honest, I’m lucky, I know, I walked in, Waterfall motive. 

Arun Kumar

So we were building REST API as I said, and we were building SOAP and REST bots. So we were writing a lot unit test to test this stuff and it was built in Java back days. So we were using Java to write unit tests. I was doing a lot of pair programming with developers and helping them, you know, writing unit test and getting my head around, you know, what things to be testing at the unit level and the API level. And then we were using SoapUI Pro for API testing and at times so we were writing a lot of Ruby scripting to do the pair testing. So as I said, it was just a backend project. So we basically delivered a lot of management APIs for them and it was like a good, good, good project. And I learned a lot and I was working one job at that time. I just finished that project after a year and a half and then like another came up and I was more again inclined towards Java. And obviously I was in my early days of QA. And I was like, you know what? I don’t understand technology. I want to stick to Java. And then again, my manager and domains. I will give credit to her for that. She’s like, you know what? For you, you’re very young and technology sort of “meta”, you have this chance. Why don’t you change and go .NET and I was like, “you know what? No, no.” And then somehow basically said, you know what? And I wasn’t into that time. And she’s like, OK, if you start working on those things, maybe, you know, in future you can go out. You know, .NET is growing so fast. They said I said, okay, fine. I started working on .NET. So we were basically building an automation framework for them in .NET and SpecFlow for the front-end. And I started working there. And to be honest, after some time I started liking .NET as well because in Java I did a lot of backend testing. I never used Selenium in Java. And for me the first time and I use Selenium, it was with .NET. And I liked the SpecFlow. And then I worked with .NET and SpecFlow for a bit. And then I moved to the UK and basically we were doing the whole platforming for ASOS. So I continued with .NET for a bit and we were like, to be honest, I never worked as a traditional QA, like the way I see QA in the industry today. So I always worked very closely with developers. So like in the company, like even when I was young, I was just waiting around for drinks outside and the people would go, “Are you developer?”. So for me, like I had that image always because I was very close to developers. I always believed in, you know, shifting the whole testing to a little bit left. So yes, in the early days my experience was not that great so I had so many white tests. But if you ask me now, I always ask you myself and I have some sort of conversation with developers as well as QAs as well. Like whenever you add a test to the next level from a unit, you should as yourself why you are writing that test there, because. first, finding a defect at that level will be, you know, in a lot of states and fixing that effectively would expensive. So I always believe in, you know, but I think your test. At the start, so obviously, if you can do TDD, that’s best. So if you follow like DTT or TDD approach, that’s amazing. But if not that, you sort of always ask a question to yourself when you go up in the ladder in the test parameters that you have.

Arun Kumar

So that brought me to the UK and then I started again. Obviously, I was working very closely with developers. When I moved to the UK, we would again, I was in .NET.,  D.NET for two years, even after moving to the UK and then we said, you know, the whole UI testing it’s sending because I was more focused on the UI when I moved to UK view as working on the ESOS website, which was mainly that I was going out to check out. So we were doing that. It is ending of chicco in the whole MECO Sobeys architecture and then we said, you know, the .NET and the whole thing is not very mobile friendly, so we need to at some point move to JavaScript. So then we said, okay, fine, you started building this thing, that Beda app and all. And then we started using web value for the testing as well. So it it’s like for me my basically do java, I did .NET and then I did javascript. Now like I’m at a point where I can do business. I don’t mind technology. I can I can do like think-tanks for it. Any any technologies. Obviously, I can upskilled myself for a week, but I’m sure technology’s not a problem. like the way I see, I think. Q Is there should be open enough Guiliano for any challenge? I dont think technology is a problem at the same time. Your basic like that, the way I see you it is your basic principle should be very strong. You should be in a position to talk to your architect talk to, your DEGLI talk to your developer. But any such challenge their design because when we say SD D. For me it’s not only testing, it’s design as well. And you should be part of the design insistence. And if they’re saying we’ll give fine C-130’s design testing. Exactly. You should be thinking too T.S.A. head because obviously FELTER Developer. But you are very inclined to like, oh, I will design my glassing that way. I examine the in that way. But as a QA Mindset, and if you are very technical, then we say SDD for me, SDD should be very technical enough and this should know about designs. So then we sort of challenge about the design saying that you know what? I dont think this will scale up in production. So those sort of think things. Subito taught veiling that ones before eighty-one V.D. to that point. So it’s mainly like, you know, thought process and then changing the mindset as well, like for me in my experience, I’ve seen like since I moved to Ireland and I started walking, had smart books, and then I came here, we had the thing again, like if I go back in 2011, that’s OK. This is scary. This is Dave. So we had a pretty much similar thing head with. We were not, you know, working very closely with developers. And then it was like, okay, developers building some code cubase testing. So you know that Coastwatch who was, you know, to fix that thing. And then we said again, or I think you should work very closely with developer. So we started that. And now we can see that improvement like the way we deploy our software to products and it’s like single click deployment. So in like different themes, like we have a mindset that you don’t have to deploy or go to a woman to test. So they live an eight hour test. We basically want to make sure that these tests can be executed on CIA pipeline itself before you deploy to a physical woman. So we deployed to Getler what goes around our test and then we only pull more solid like Novey added I stay away. Pretty much half of the teams are doing single deployment. And then it’s it’s amazing because the transformation that I’ve seen, I know everyone is responsible for quality. It’s not like Q8 the dysfunctional quality. So we basically do like I work pretty closely with the key rededicating here and obviously the architects in the company. So we basically want to make sure that and like my ague, idiotic to feel he’s helping me a lot with that today. That’s easy. Like it’s not on Liguria, you know, developer so take ownership so it’s everyone’s responsibility to deliver the quality. So. Q8 Just making sure that we have that process, but obviously we are expert in that domain, so we make sure that we have right framework for it. I think so. Okay guys, let’s use Cyprus for UI testing. Let’s use that. I saw it. Rest assured feedback and testing. But again, like for me, personaly , like I’m a big fan of having automation. testness same Technology. That the Arab League isn’t using so, for example, if I’m writing of Youssef’s application or the ACT application, I want my UI test to be in javascript so that you don’t develop us will be familiar with that thing and they will be able to write it. If my developer is writing java scripting his day-To-Day life and he fired decided as a key architect, the principal guessing that you know what, I want to how you are testing found work in dot net or java then obviously I I dont think they will be able to help me in writing those test. Then QA Will be in a different line and developer should mean different lines . I believe in that. That Yachad test automation should be in the same technology or same language that your application is a different so it will be easy to test and you know e.g. to execute and you know you went in CCD pipeline that would help a lot. So, yeah, so although those are the things that we have and also like I’m a big fan of contract testing as well because I believe in drawing line between different systems. So I know like in there that it is still way that they with their software is we say, you know what? Because we don’t understand a bit less. Sometimes we say we don’t know much detail about the system. We don’t know what’s the boundary between different systems. And when you start automating system without knowing those things, you will have so many test. And then you will never, ever would be able to run those tests. And you’ll see A.C.T. pipelined because those test will be flik enough because your test depending on different systems. So getting each and every system in a sync will be difficult some time because when you think about CICD. Those systems should be in isolation and you need to have a boundary with different systems. So we were facing that problem and then we like, okay, why, how how do you know overcome these problems? So we basically implement that contact testing it. And with that, like let’s say if I’m working on one application, I will have my boundary line. These are defined with different applications saying that, okay, I’m application a there’s application and I’m looking at application being application C. So I will have a contract with those applications saying that, OK, I will make this request to you guys and I want this response. So those requests and response will be recorded into this and file and both application will have to sign that. And that will happen to the CIC to pipeline. So there’s no manual process. So I can give a good example. So let’s say there’s a take out application. Who is talking to one of the women? Broy that is going to be the stripe or the dark ash or whatever it is or let say Apple Pay. Now we can have a contract with Apple Pay saying that I will call your EPA with this data. I want this response and that will be recorded into address and violent. Let’s say my company and Apple both will have to sign that and they both will. Somehow how to validate that in this CIC pipeline. So in that way, one, we can test out application in isolation. Our test will be at almost enough. There won’t be any flakiness in the test because we know what’s the response from these guys. So we can always mock that because if we don’t have contact testing in place, then still we can look. But then there’s a risk because we don’t have any baseline to mock multi-room. So as I said, I’m big fan of conduct testing and I think that’s just a way forward for it. It’s not only for QA. I think all sorts of things. And engineering because low obviously everyone is going to this microSD always architects at any photo microsoft office in a company will have 100 services. And if you underwrite the test, I don’t think it’s a wise idea to test all one vendor. So all together, yes, we can have on, let’s say three or four or five core business users on these as and went best, which we can test in a pro-Putin disenrollment, but to test everything. I don’t think every Sobeys will be deployed. So you need to find a ways. Mitchy, I think on track testing can be a good fit. And for us, like it’s we can see he was ready to either say those A.C.T. pipeline for different applications like we can deploy two products and in five minutes and we don’t do any manual testing, all all the checks will be performed in the pipeline itself. So so that this is how I see it. Like, you know, my my Zandi’s like obiously. I always look for the new technologies. It’s not like, well, javascript is the one that I want to do   java the one that I want to do. I always keep learning like if something new comes up. I basically, for example, for recently I was just working with localist for performance testing and load testing because for front-end we use Lighthouse. This is also like we introduced recently and we have that in the byplay and we have a performance metric set and obviously if something goes up and down by pipeline will fail. The 1w Duplo got sample back-end we use localist to you to do some sort of performance. Testing was also given as part of a biplanes and basically localist is like by some Westwood’s. So I like recently I did some phyton as well. And as I said, I think every technology Same so we should not limit ourself and I don’t think we can use Hamdoon for every testing. So different TOOL have their different objectives. Like if I say I want to test everything with Selenium, yes, I can do it, but I don’t think that will be a good approach. So maybe Selenium is good for something they address. SARP is good for something. Rest assured is good for something. So we need to choose the right tool for you know to do this. Focus testing. Otherwise, if you start using one tool for me, we use high-price Hatful UI testing, but that’s not for closed by the testing. That’s for functional testing. And it’s a very. Good tool, which I to be honest, I can see obviously, though, that tools sex happens in the market, but in Cypress, basically you can do your functional testing in a very good way. And that based X you guys need is very fast and you can’t run everything in the pipeline. You can mock all that. Equisearch are waiting outside the budget so you can have like a good example. You can have Cypress for a functional testing, which you can have let’s say 100 functional nice job application. Then you can have one of the task of them. Locatable you set up guessin it in javascript to do crossbows as low solice goals to do ice testing it. You can eat videos night OLEDs, protect the web that are you. But your test should be let’s say for 100 functional test which pretty much tested your application. But now you just need to prove that. Will my application work on different browser and different ways? You can only have four or five core business entities so that because executing those Selenium tests will be expensive. So you need to have very minimal days. But obviously at the same time we should not compromise on the code godess or, you know, business coverage as well. But that that has to be come look at it like the way we work here is we work very closely with the developers and product on the as well. And we say, you know what? Okay. For this thing to go to unit test for this thing, we have API test. As I said, we have this toumbourou Lattakia. Whenever you had a big test, you sadowski you shouldn’t or sense why I am doing this API test like a like on D-S.D at unit and obviously that thinks that you can’t test that intercloud like if you want to test it Chris or SCDP. You can always start esti to balloon. You have to go. You can’t start intercloud. You have to go to it if you allow it. So. So but we have that thing that we sort of we always ask that question to ourselves before we add that test. Because as I said earlier, whenever you do at best up putting your test pyramid, it’s very expensive to maintain that test. And, you know, unspent, expensive to fix those defects as well. So we have that sort of mindset and themes. And like I do, maybe Lady Frequent, you know, of seasons with teams saying that, guys, this is how, you know, we said we should work out, we should have our mindset. So, Same, for you, UI test as well, like we say. Okay, fine. We have unique tests. We have a P-8s, then we have functional despot’s as a central for UAB Cyprus and then we have crossbrowser testing, which is any tools can be used like obiously different tools have their different purpose. But I’m sure based on your requirement you can pick any tool. And then on top of that you can have some sort of exploded testing. As I said, for like UAP performance we use Lighthouse, which is also in the pipeline is very easy to integrate just if you want to do. Manual testing. You can test in chrome so that obviously that of different tools and then the it’s tests. We need to find which tool is good for application. This tool is good for our infrastructure, the kind of infrastructure we have. But the only one thing is obviously as long QA you wont be able to achieve this. So you need to work very closely with your team and you need to be like okay. I am one so scrum developer. But because the way the season ending is no I don’t see QA and do as I do different streams. It’s ideally a unstained but obviously being a QA mindset, being a QA expert, we will be able to assist the themes with the best framework that can be used and obviously we can do the best quote work work. But then if a developer is working on a dig at P.O.S., so we’d be able to at best and attack you. You should be basically approving those mods request and if there’s any gaps, you should be leaving. No comments on the mods request. Also, you can do better programing like I do a lot of programing as well. I’m a big fan of their programing, so a data complex ticket. I always, always say that guys, if you want to lose on paper, let me let me know. I’m always available. So I do pair programing to different themes whenever I have that opportunity. I’d only say that because I know better programing and I think everyone in the QA should think on those lines because once you upload it to the gaurd, if you know that, okay, you know what? They’ll look and it’s not difficult because I know a few guys that think that, oh, this is a difficult task. I think nothing is difficult these days. You find everything on the Internet. If you take my personal example, like if 6 the bag, if someone would say, you know, can you build a state p-a as they broke? I can, but maybe it’ll take me a month. But know someone will ask me to do that. I said I can do in three hours because with the whole docket and everything and if you just go to the internet, you can just spin up a mighty good content on your machine like dominatrix. You can have a springboard condensed in 5 minutes and you can have everything up and running and with like teams like C.H. foget Labe and second seei you can have a property SCD like 2 3 hours, which is amazing because long back languaging zenk ganks and herd centered on it. It was not very friendly and liano setting up those things because local was nored there. So you need to have a machine to run a different opening system, do it undefended abase and things like that. But these days it’s very easy. So like me should always think from a point of view, say that ok, if I’m building something, I should be able to run this before vidoe deploying to any woman. So we should start thinking about, you know, balkanizing stuff, you know, have a different content and then you sort a keep in a mind. About how to scale these things up in production so it’s not only doing a functional testing as a good QA, you should think about application monitoring as well like and that that should happen before due to blow global production. So you should start thinking from a more of or obviously that if there needs to be different states, that’s OK. I’m a technical QA Yes, you have to be technical. But then there are ways that you need to step back. If your application is a mature enough, then you should start thinking from a point of view side. That’s ok. I’m OK. Estimate. So you have to have that right. So this is why The QA role is very important. So you need to be a part of team. They like obviously people will say that I’m contacting contradicting myself, but this is how our life is. So you need to be very close to developers, get the application upfront and they have a good test at a place. And then you need to start thinking. Will this work in production? Is it obvious already? Will this. Let’s say tomorrow the app is ready and then there’s another team who wants to work on it. So you need to be on of that will be able to deploy this in any and all manner. Will I be able to do a local development setup on Mac OS Linux, Unix Windows? So because it can be different guys. So that documentation is also very important and your thought process is very important. So let them eat. All the documents should be part of your code to itself because confidence is good. But time you need to bookmark these Basia. So I think it’s good to have documentation as part of it. Even if I if you think your did me file is getting too big. You can have different trade may find for different things. For example, read me file for a local they’ve set up that read me file for all the codes that ravaging read me file for the automation process, like having your automation tested on made and different blood-soaked. Okay. Local stores for testing cypresses for UI testing symphony. the best for a beta testing that I sat for a bit. Testing DDP things. Everything should be documented as part of the quadruple. So if there’s a new a guy basically join our team. You just say ok you know it because normally people still get follow. They stay with the SEC Lundy’s triple and you should be good to go. So. So you need to have that mindset as well. QA it. You need to make sure that your product is basically your product can be used by everyone. It’s not only developer. So you need to see from different stakeholders point oversight from vertical on our side, from a customer one side. So basically your mind user keeps changing on mind the for a week. You like acting as someone for another week? Acting as someone. So it’s Eslake. Then you go a bit closer to like OK, we are ready to deploy to productsand because you fell working on a new services. So obviously Adderly days you will be very focused on that stuff and then you will start thinking on those personal line that okay with this work and products and Hochuli scale deseve, this sort of dashboard we need for monitoring. Is it a client side application as it has always had application? Do we need not really. Do we need Cubana? Do we need something else? And then you should work very closely with your client or business guys thing that will give you a sort of dashboard that you aren’t. What are the critical flaws? So we should be creating those dashboard. We should be testing those before it would implode production because we need to know because they can be few things that are expected behavior. But if we do appear to production and without knowing them, then they can be annoying business. And you know, so it’s just as a QA I think we need to step up as a team and we need to keep changing our roles. As you know, the way the actor that basically plays in a different movie like different role. So for us also, like in a whole SDLC lifecycle, we need to keep changing our role and obviously keep learning new stuff. So it’s not only, okay I’m a QA. I will do I will do it, you know, what is written done on the target saying that these are if you accept masonite idea and these are fulfilled. So I don’t think that that’s the right thing to do. For me, I think we need to do a lot more things. And I think there’s a lot of scope in the QA industry  that I think is a good thing for us. And we should, you know, work very closely with their team as well as what they doing in the business, but we need to, you know,  scale our technical skill as well as a different mindset approach. 

Jonathon Wright

I think I think you’re absolutely right. And that was a fantastic intro. Some of the challenges you’d be doing. I got some I made some notes and some of the key observations there, which I think are really, really useful for the listeners. I love the idea of the same language. I think that’s a really good, good point because it does mean that you deviate from the stack if you. You switch to something that isn’t native. So I’m in the same kind of the same boat as you at the moment in the sense of, you know, we’re developing react native. So it’s JavaScript. You know, part of it is I want to be able to release into that pipeline. You know, of course, you know, it’s going to be different because of the tools runway. to get an app into the Appstore are going to be different. But I need to be able to fit into the CICD landscape, which is great. I think, you know, your idea around thinking ahead is brilliant. You know, I think the idea of being able to sit there with when the code’s been, you know, conceived to literally say, is this going to be able to scale, you know, is this going to be the right kind of architecture? You know, sort of talk the other day which was saying that you know, people use design patterns because they’re the current thing. Right. But maybe that’s not the right one to do. And you can also kind of gives you that opportunity to do. 

Jonathon Wright

And I know you mentioned ATDD and BDD and TDD. 

Jonathon Wright

But, you know, the idea is, you know, if you look at something like specification by example for Geico and them kind of executable specs, you know, you might have a well, this needs to be 250 milliseconds. Well, what why does it need to be 250 milliseconds? Well, it does, because, you know, we might scale up to a million. And, you know, you need to understand what that volumetrics are looking like. So you need to have an understanding of what you put in there that actually says if this runs less than that, then it’s you know, it’s not to be right. Because, you know, you can’t make it. You know, there are certain discussions where, you know, rest isn’t the most efficient way when you scale up. So we had a problem where we had a simple rest endpoint, which then put everything you would post into Kafka. You know part of it is, you know, once you’re on Kafka in a big assembly like an enterprise service bus, you know, part of it is you can get a guarantee, the delivery effect. You know, you’ve got consumers, you know, you can go down, it can come back up. You know, it’s not a problem. But here in the front API is, you know, it doesn’t guarantee delivery, right. So if it comes back with a 5 or 4 or comes back with something which is an error, you know, how does it deal with the error handling? How does what all those negative tests, you know, using rest assured, you know, you’re going to go through and you can stop able to write those scripts that kind of say, I’m going to do the negative parts, you know, do the happy testing as far as the cut of the contracts somewhere those contracts go to go to, but also, I can understand well for marking out the server with wire marker or whatever it may be. You know that I understand that some of the payloads that could come back up, you know, that that that that contract, you know, that already exists or so, so today. So, you know, you need to deal that and you got you’ve got upstream and downstream systems like Stripe. You know, you’ve got you to know, the payment gateways, which you’ve got codes which can automatically say there’s are no funds available. So you got to write those into your scripts to say, you know, the card being declined or, you know, some other thing. Say, you know, part of it is there’s a lot of stuff that you know, is your advice around thinking ahead makes a lot of sense. And it also it’s that mentality is it’s kind of going well within the contract testing, which sounds like you’ve done some amazing things, that small box. You know, part of it is, you know, you had to stand where your ecosystem is and where it ends. So you understand just thinking around which kind of nodes you’re actually going to be in and out of scope. You understand what payloads need to be delivered to each one of those and what they make the request-response pairs would be for each one of those transactions, even if it’s just a template. And then at least another contract testing can go on with the upstream systems that can take those as a reference to what the schema looks like and then what they could potentially be expecting from, you know, an approved transaction, for instance, into, you know, that the backend systems say, you know, I like I love the idea of the marks and the steps of the shims and the idea of really understanding what the scale is going to look like. I also love this idea. If the been able to deliver into the pipeline and, you know, also this kind of low code kind of approach that, you know, you’re documenting in your, you know, get lab or you get hub repository, you know, you’re giving people the setting of how they would build that locally. So, you know, if they’re spreading that upon now on a Linux box versus, you know, maybe they use Docker for Windows or a Mac, you know, is, you know, for a schema registry perspective, you know, is there any configurations that different? You know, is there any kind of contagious that they’ve got to pull down any dependencies, you know, understanding all that really helps, and I think from the documentation, it’s one of those things that just enough is right. And it also supports new staff as to where to go in and enter and able to pull those down, run them on the local one, then deliver them through a pipeline and maybe go to OpenStack or wherever else you do. But also the idea of things like monitoring is code, you know, the idea of being able to, you know, actually have some rappers around. Well, if I’m deploying Buycott, Prometheus, if Prometheus, what’s my data? I built a pod to Cabana. You know, what is it? What is a key important is the eye ops, you know, is it the amount of time, you know, just for the requested response to CPU? What is it that you actually wanted to understand and monitor from an operational? So you kind of then thinking not only just ahead, but you’re thinking on an ops perspective, if you know, what would those guys be looking guy? And if they’re trying to do you like root cause analysis or pinpoint failure, then try to understand where the issues come from. Then they’ve got all the monitoring, they’ve got all the logging that requires they’ve also got a history of what they, you know, everything should look like. So you APM can do that kind of capture off of and help people diagnose issues in production. So there’s a lot of really valuable lessons that you’ve kind of added in there. And it sounds like the maturity of every role that you’ve taken is increased study. Each kind of step, you know, for people who are trying to learn this technical stuff, do you have any kind of tips for kind of places that they could do their online training? So, you know, like Udemy, you know, where do you find that you get the best resources when you go online? 

Arun Kumar

I think the bonus for me, like as I that earlier if your basic programming concepts are good enough, then I think learning these new things it will be easy because if you take an example of any of these new tools that you have in the market, they are just up there on the Selenium. So if you know Selenium, you can do these, not do it. So for me, like I don’t I’m sure like Udemy and these Linked-In lending and tool learnings are all good. But for me, like I don’t learn stuff on any of these paid platforms. I just find I just go to that tool and just take a look at their documentation and try to, you know, get my hands dirty with that. So I basically played on the load and then if I got stuck somewhere, then maybe I just search on the Internet like, what’s this? 

Arun Kumar

But I normally don’t do any costs for any new technology that I learned. I just go to the documentation. If I want to learn a low cost  I just go to the documentation. Do a little bit of research first I run without Dockery’s, so I just do a normal installation play with it and then I just basically do the docker one. So I always basically when I try to use something, I want to make sure that there’s — for it and that it’s stable. But I said when I learned I learned without Dokken I stuff and I say okay. They had already made that because when you want to like for example there are so many automation projects where you can just learn stuff, you can write code, but people are not executing those tests in their everyday life that’s because they see these test either flakey or not easy to run in the pipeline because for example, as a QA, you say, you know what, I want to add these tests to the pipeline and then tech lead or architecture or one of the senior developers will say, you know what, we can edit, but can you make sure that your test is not flaky? So it’s like and then, you know, running those tests like a digital Oaken, he made for the framework that you’re using, that will be very helpful. 

Arun Kumar

So, for example, as we are using Cypress for the front-end testing and it’s very easy for us to run that in the pipeline. We just ran on Chrome and Firefox in the panel for front-end testing and it’s already handy same for low cost did it. Okajima [0.4s] So it’s like for me, like I don’t learn. I don’t do any full-online learning. But yes, I take a look at the tools. First, I do some research like which is the new tools. I always make sure that I spend I have some spare time for my learnings in a week like every week I just use new in the QA space what’s new in the developments it’s not only QA, I just look at the development as well like which film book is good. What’s happening with the whole, you know, how the system works, what are the best way of testing these? And then if I find something new, I just take a look at the documentation of the tool, and then I just get up and running on my local machine and then I will make sure that it’s not only up and running, I have some sort of test project to have that in CICD as well so that I can just go and sell that to business saying that guys because otherwise, it’s very difficult. 

Arun Kumar

I’d if you were going to a big company and you did some sort of use, you know, local machine, but that was just to hold rightest. But that’s not important because of the whole and Glanzer nazy important. So you can write this, but then your test will be on your machine. It may be on the other GitHub depot, but we are not executing those tests on a day to day life. So we should always think about when we think okay, fine, let’s use this tool so we should do it and do and evaluate that. Okay, we’ll be able to use this tool as part of the A.C.T. and why we need this because I’m sure we already have something. 

Arun Kumar

Every company has something in place, so we need to prove that. Okay, these are the days that we have. These are the problems that you’re facing a domain B1 which these things with this new tool and then you should go with a small P.O.S. which is and doing that is it have a sort of CACD and then maybe propose your manager at Aldine or someone in the business. So but buddy, I prefer this approach because if we don’t learn then obviously the Vatican or D.N.C. I think will be lost somewhere. 

Jonathon Wright

So do you have any kind of test projects, you know, that you use to demo your end to end capabilities? So like I use. So we react native, for instance. 

Jonathon Wright

You know, I ‘d want to do it with a Dubie app, you know, or if I’m trying to do something like using locusts, you know, I’d like to, you know, hit some performance, say Z0. You could use something like Blades.demo.com As that kind of a sandbox environment that you can hit the API. You can hit the front end, you know? Do you have any kind of favorites for that kind of stuff? 

Arun Kumar

Solich for me, as I said, a doubleness that I always let’s say if I want to test legitimate, it already found this locust. If I want to Cyprus or any of the UI frameworks, I basically build a small UI application for myself and have that in the pipeline that either then hitting the existing one so that I can do the whole and went pipeline because you know, I need to see that. Okay. Let’s say if I want to propose something to the act or eulogists, then it’s very easy. I can see that download from one of the GitHub reports on that and then the next thing that gets HelloWorld GitHub up. Beauteous application or some sort of form application, something like that. And then I basically have that in my biplane deploy that as part of my biplane and then don’t test on it. So I basically [0.0s] follow that approach. SBIC Yes, you write sometimes I just may find someone on the Internet that if I want to do some fixing, but I normally forefoot approach where you build an application, if you’re not building, it’s fine. You can find on the Internet and then you try to host that on your local first, get your head around, and then you need to transform that. Didn’t do a pipeline on you get the benefit that I get LeBert so easy. So I get left for my personal projects and I follow that approach. I try to run unit tests even though if I don’t write and then I can add some at any update there says what are the pipeline as well? I deploy in my pipeline, which is, as it said, not on the physical enrollment. It’s deployed somewhere on the Cotopaxi good that I had on my test. And then I had my UI test as well as part of the pipeline before it is deployed. So it is like I follow that uploads. But sometimes, yes, if I need a very quick window and I just take one of the existing websites, if you’re playing with a UI, you can just take any e-commerce website and then play with it. 

Jonathon Wright

And you know, I was in I flew back from Bordeaux a couple of days back and we were using Captain. I don’t if you see captain, it’s a get repository for kind of unbreakable cut pipeline. But the idea is it works. We get Lappe the idea is it gives you kind of those quality gates that tells you to base on lots of historical runs what the know deviation of that execution is at different levels. So obviously at UI performance API, it’s got all that information and it kind of gets into that kind of you can see where you get score different environments and you can drill down into it. Do you find that you’ve got any tools that you like within the CICD pipeline fit to do to something? 

Arun Kumar

So to select a vainest for us like you would get the labor to set and we have some check as part of a pipeline. For example, if I want to deploy to enlargement, which is like let’s say my first environment, which can be developed in my mind or staging that are different names that you can follow. But if my. Obviously, if my unit test is failed as part of my pipeline, then obviously it will not go further. So let’s see if anything fails and then you won’t be able to deploy. So Same goes, as I said, lead in the unit test would and API test and we’d any white test before we deploy. So if any of these guys failed, also we validate the contract as well that we have a different team, let’s say different applications. So that also we related before we deploy so we make sure that everything is green. Also, we check on woman’s health check as well, because sometimes what can happen is your code is OK, but there’s a problem the interests exit. So what we do is before we deploy, we make sure that alignment is healthy. So we do all the quality checks which we have in a separate get laid out and file because I decided that I think a good thing maybe for the audience had AIDS. So the way I think is you can normally you have a blanketly IBM and file for the whole project. But the way I see the. You need to have a different get labial on malphite for different activities. So for example, all the quality checks should be in one. Get Lavie on the file. So then In-Q-Tel had something you just update that GitHub gets Lib-Dem and fight. Same goes for, you know, the static chording unless you stink. You can have a Yamal file, you can have five slotted something for reporting. You need to have a separate get Dave on that fight so that you’ll find one B-to-B. So so we do have these all different quality checks before we deploy. And then I say we do then woman health check as well. So we have a health tech URL. We just hit that. I said, OK, is it green? Is everything okay? I’ll be able to connect two different systems, blah, blah, blah. Oh, look. And then we deploy after deployment. The first thing we do is we check it again, obviously, and then we do some validation. And again, obviously, everything is automated. So we deploy, we do the health check and then we check of it and our functional test or some sort of validation in the pipeline. And if that’s good, then if you go to an Asian woman, a name that’s good and go to Nickson Ahmed and then obviously follow product production at home in and are doing. But we have a manual click. You just click and then go to. 

Jonathon Wright

And as far as kind of your pride, so you’re going to do continuous deployment over continuous delivery there. But you also once you’ve got into production, do you use any like real user monitoring? 

Jonathon Wright

Do you add anything to your APM aims to do kind of just check things are okay? Synthetic monitoring tests. 

Arun Kumar

So we already have, as I said, these Dysport board buildup and we have alerting policy for a different application that okay, for example, this particular source will get these minute quest and should, you know, respond with 200 or do you know, based on the Yoda comment, we have all these configured. And if after any deployment, obviously we boost application Watson engagement every time and we deploy it, go to our logging systems, which I would ever use. 

Arun Kumar

And then if there’s anything wrong, you will get an e-mail. obviously. As I said, we have a predefined alerting policy. So if something is wrong, you will get an e-mail saying that, hey, this is not working. And obviously, if you are building something new, so it’s just like that, there’s a tradeoff always. So if you are doing some improvements on the existing EPA or a facility that you have, you don’t how to build that monitoring thing. But if you are introducing a new resource, then obviously has part of that development. We built this Hedgeville so that when we deployed to prediction, we basically make sure that this thing is, you know, getting populated and reacting, you know, and we are getting that response as expected. So, yes, we do consider those things, as well as part of the deployment but I said it’s pretty stable now and then. Yes. If something goes wrong, we get an e-mail. Now, you know, due to the coronavirus I will get an e-mail yesterday oh what’s happening? Because you are not getting the, you know, expected traffic because people are not doing stuff so it’s like. 

But these things also we need to keep revisiting them because otherwise, it’s going up or down. And then, you know, you need to keep revisiting your alerting policy as well. Okay. What’s what? Let’s say you roll out into new countries, then you need to think about your alerting policy as well because it’s going to go up or down. So but yes, we do consider those things such as well as part of the release. 

Jonathon Wright

Well, thanks so much for that. It’s been a great session today. I really enjoyed the time and congratulations on the new role as well. So we’ll definitely have to get you back when you’ve been there a little bit longer. And you’ve got some more exciting stories to share with us. All right. Have a great day!
