What is "test automation"?

Test automation refers to the use of specialized software tools to execute tests on a software application and analyze the results without human intervention. This approach significantly enhances the efficiency of the testing process by allowing repetitive test cases to be executed more quickly and consistently than manual testing would permit. In automated testing, scripts are created to perform test actions, which can then be run whenever needed, providing quick feedback on the software's performance and functionality.

By utilizing automation, teams can achieve faster release cycles, improve test coverage, and ensure that tests are performed systematically. This is particularly beneficial in agile development environments where rapid iterations and frequent releases are standard practice. Additionally, automated tests can be run on different configurations and environments without additional effort, making it easier to catch unexpected issues early in the development process.

In contrast to manual execution of test cases, which is labor-intensive and susceptible to human error, test automation leverages tools that can execute predefined scripts, analyze the outcomes, and report the results accurately. It is also distinct from simply automating the testing environment or developing testing standards, as those aspects pertain to enhancing the infrastructure or guidelines surrounding testing rather than the actual execution and analysis of tests.
