What is a QA tester?

Quality Assurance (QA) testers are critical in delivering customers high-quality, perfectly functioning software and web applications. Working closely with programmers and developers ensures that new and existing programs are free of bugs, glitches, and other user experience issues.

QA testers play an essential part in the development process. Along the way, testing will allow QAs to identify issues early on and make changes before they snowball into more significant problems. This saves time and money by resolving bugs earlier in the product’s life cycle rather than going back and making changes after the product is released.

QA testing ensures you won’t compromise security or user experience when adding new features. By involving a QA tester from the outset, it’s easier to ensure that your product will be able to stay secure and perform well as it grows.

QA testers follow a defined process to test software, document their findings, and report their results. QA testing is done by a separate group of people outside the development team, providing an objective evaluation of the product. Their impartiality helps ensure that users get what they expect and that the product meets government and industry guidelines.

As a QA tester, you’ll need to develop technical expertise and knowledge of many different types of testing, such as unit testing, integration testing, system testing, user acceptance testing, regression testing, and more. The more exposure you have to these essential QA testing aptitudes, the better off you’ll be.
