QA testing, or quality assurance testing, is a process that is used to ensure that software or a product meets the required quality standards. It involves a set of activities and techniques aimed at identifying defects, errors, or other issues that may impact the product’s functionality, usability, or performance.

The main objective of QA testing is to validate that the product meets the requirements and specifications provided by the client or stakeholders. This may involve testing the product’s functionality, usability, performance, security, and compatibility with different platforms or devices.

QA testing typically involves creating test plans and test cases, executing tests, documenting results, and reporting defects to the development team for correction. The testing can be done manually or with the help of automation tools, depending on the complexity of the product and the available resources.

Effective QA testing is crucial to ensuring that the product is of high quality and meets the needs of its users. It can help to identify and fix defects early in the development process, saving time and money in the long run and improving customer satisfaction.
