Software testing and quality assurance (QA) are two critical components of software development. While they are closely related, they have different goals, which makes understanding the difference between the two essential. Testing is the process of running software through a series of tests to detect bugs and other errors, while quality assurance is a process that helps ensure that software meets certain standards and requirements. Together, they create a powerful combination that can help ensure your software is bug-free and meets industry standards. With the right tools and processes in place, you can ensure your software is of the highest quality and meets all user requirements.
