The practice of analyzing and validating that a software product or program accomplishes what it is designed to do is known as software testing. The advantages of testing include bug prevention, reduced development costs, and improved performance.
Manual testing is the most hands-on sort of testing and is used at some point by every team. Of fact, manual testing is difficult to scale in today's fast-paced software development lifecycle. To automate the software testing process, automated testing employs test scripts and specialized tools.
Software testing is defined as the process of checking and certifying that software or application is bug-free, meets technical criteria as led by its design and development, and meets user needs effectively and efficiently while dealing with all exceptional and boundary instances.
