Application Testing refers to the process of evaluating and validating the functionality, performance, and quality of a software application. It involves a series of tests and checks to ensure that the application meets the desired requirements, functions as intended, and provides a reliable and satisfactory user experience. Application testing typically includes various types of testing, such as functional testing, performance testing, compatibility testing, security testing, usability testing, and regression testing. By conducting comprehensive application testing, organizations can identify and resolve any defects or issues, improve the overall quality of the software, and deliver a stable and high-performing application to end-users. The goal of application testing is to ensure that the application performs optimally, meets user expectations, and delivers value to the stakeholders.
