What Is QA Automation?

Quality assurance (QA) is often done manually; however, there is software designed to take the load off of human participants and reduce manual testing. QA automation is done through software designed to explore, test, and report on its subject. Test automation will often apply artificial intelligence and machine learning (AI/ML) to better service tasks for test optimization, intelligent test generation, execution, and reporting.

What Are The Benefits Of Automated Testing?

Automated testing can help speed up the process of delivering quality software faster, known as “Quality at Speed” (QaS) or sometimes “Quality at Scale“. Automated testing is an important component of DevOps toolchains and agile methodologies, which helps deliver on QaS. Mobile automation testing tools can:

  • increase feedback speeds
  • accelerate results
  • lower business expenses (hourly wages)
  • increase test efficiency and scope
  • detect defects earlier on in the development process
  • generate more thorough test results

Automated testing is also often an important part of software development that uses a continuous integration methodology.
