10 Latest Software Testing Tools QAs Are Using In 2021

This article will help you quickly compare and evaluate popular software testing tools—the latest software testing tools that you can use to build better software in 2021.

The software goes through a variety of tests during and after development in order to make sure it’s as polished as it can be before opening it up to general users. With the evolution of agile transforming the role of QA, we’re finding different ways to use tools and leverage them in our software testing processes. 

Each team is different, and one tool may be more appropriate for different types of testing or different types of software. That’s why a thorough evaluation of your software testing tools is important before you get started.

Do you need general QA software? Website testing tools? Are you working on a smartphone app and in need of mobile automation testing tools? There’s a software testing tool available out there for you—you just need to find the right one. 

In this article, I will evaluate the pros and cons of each quality assurance tool on this list. I will also answer some FAQs about automation software testing to get you started.

Quickly Compare & Evaluate The 10 Best Software Testing Tools

These software testing tools can help you automate testing, perform a wide range of software tests, and increase product delivery speed for any automation software application.

Types of Software Testing Tools 

There is different testing software for different areas of the software development lifecycle. Here are some of the main types of software testing tools that you might come across during application testing. Software testing solutions may specialize in one area of these testing types or that may cover multiple. 

Functional Testing Tools

Functional testing can be further broken down into subcategories like unit testing, integration testing, interface testing, beta/acceptance testing, et cetera. 

Software testing tools in this category will be responsible for identifying defects before market release, aiding clients in testing their newly delivered software, and/or testing for backward compatibility with older software and compatibility with different web browsers and operating systems. 

Non-Functional Testing Tools 

Non-functional testing can be further broken down into subcategories like performance testing tools, load testing, security testing, install testing, et cetera. 

Software testing tools in this category may be responsible for testing the installation process across different hardware and OS, checking the software for any security issues or possible weak points, and/or testing the load capacity for given software to see if it can handle a given volume of users performing a given volume of actions. 

Automation Testing Tools

Automated testing tools are designed to evaluate the expected outcome and compare it to the actual outcome. Automation testing relies on scripts or software that perform repetitive, mundane actions, and report the results. Automated software testing can be used to perform actions that are difficult to replicate manually.

Agile Testing Tools

Agile development is a methodology that designed a product in organized, incremental steps. Therefore, agile testing is a software testing solution that then tests in similar incremental steps, testing features as they are developed.

Testim is a low-code tool with a modern, intuitive UI. Tests are created with a Chrome extension that records a user’s actions. Tests can be edited in the Testim visual editor to rearrange steps, create reusable groups that are shared across tests, add assertions or code-like functions, including loops, and conditions. 

Cross-browser tests can be initiated by the built-in scheduler or from a CI action. Testim integrates with all significant CIs. Testim’s test status feature enables users to treat test failures differently as they run in the CI (stop the build, pass the build with info only). Testim integrates with popular version control systems for code/test branch synchronization and collaboration and bug tracking tools. 

View test results from the dashboard that shows the last ten runs for each test. Failures can be quickly diagnosed with failed step indicators and before/after screenshots, parsed consoles, and network logs. Testim even aggregates failure types to help triage test run results. 

Testim’s biggest value driver stems from the AI-powered locators that keep tests stable, reducing maintenance costs, and customer case studies indicate fast authoring and root cause features also generate time savings.

Testim is free for up to 1000 runs/month. Higher-level plans offer customized pricing upon request.
