The main objective of quality assurance (QA) testing is to ensure that tested applications meet all application requirements. QA testers must complete comprehensive testing across individual applications and platforms. If integrated systems are being tested, an integrated application test follows the individual tests to complete end-to-end testing.

Executing QA testing can be both a frustrating and tedious process. Testers may receive an application that is deemed “ready to test” from the development team that in fact has not been thoroughly unit tested. In addition, QA testers may not have a complete understanding of the application's intended functionality. Testers may invest significant time reporting low priority issues and probing the development team with questions as a result. High severity defects are left unaddressed, waiting to rear their ugly heads in production.
