A QA (quality assurance) tester is someone who tests a product, usually before it is moved to production, to find defects or errors. The QA tester tries to use the product in typical and unusual ways to find any issues it may have. While this a general term used in most industries, the specific job duties vary significantly. For example, a technology QA tester examines software or websites for ease of use and relevant content. During the review, you record problems, known as bugs, and report them to the development team to be fixed. In the gaming industry, a game QA tester plays a video game with a critical mindset, assessing the functionality and overall experience.
