"Test automation" is a process of developing and executing tests that can run unattended, comparing the actual to expected results and logging status. It is also a tool support for all aspects of a test project, not just test execution. Hence, many organizations prefer automated testing.

Like other SDLC process, designing is done before coding in test automated system. Next step of automation is to track and safeguard the code. Thus, source code management is used for this purpose. At the end, test automation will have bugs which should be removed by proper planning, tracking and testing them. Later, user documentation is made to introduce the users on how to use it.
