QA involves a methodical procedure of monitoring and reviewing several facets of software development to find and fix bugs and other deviations from specifications. Requirement analysis, test preparation, execution of tests, defect tracking, & report writing are all a part of this. First and foremost, QA works to eliminate bugs and guarantee that the final product satisfies all quality standards.

As an aspect of QA, testing ensures that software operates as expected through predefined test cases & scenarios. It is the process of running software to detect problems like bugs or unusual behavior. Each testing stage—from unit to integration to the system to user acceptance—contributes something distinct to the verification process.

Quality assurance and testing are crucial because they guarantee that a product will perform as expected in various conditions. Quality assurance (QA) & testing help save time and money and improve the user experience by finding and fixing bugs earlier in the development cycle.
