Quality Assurance (QA) is an important process used to ensure that web and software products meet the highest of standards. It involves testing web code and applications to make sure they are of the highest quality and functionality before they are released to the public. QA usually follows code reviews; where code reviews validate the coding approach and best practices, QA validates all functionality is working as required.
QA is typically part of the software development life cycle (SDLC) and involves testing for usability, accessibility, reliability, and performance. QA can be done manually, or automated tests can be used to test code and software. Automated tests require additional development, but for business critical features they can help ensure consistent product quality.
Quality Assurance is an important process, as it helps ensure that the product you are releasing is of the highest quality and functionality. Not only does it help the development process, but it also helps ensure the customer receives a high-quality product.
