Automation testing is a process of changing any manual test case into the test scripts by using automation testing tools, and scripting or programming language is called automation. Automation testing is used to increase the efficiency, effectiveness, and coverage of Software testing. Automation test engineer uses automation testing tools to automate the manual design test cases without any human interference. And these testing tools can control the execution of tests, access the test data, and compares the actual result against the expected result.

Automation is the use of machines to perform previously performed by humans or, increasingly, jobs that would be impossible without them. Although “mechanization” is frequently used to refer to the simple replacement of human labour with machines, automation generally refers to the integration of machines into a self-governing system. There is hardly a part of modern life that has not been impacted by automation, which has revolutionized the fields in which technology has been used.
