In the context of testing, what is a primary goal of automation testing?

The primary goal of automation testing is to reduce manual effort and testing time. Automation helps speed up the testing process by running tests using software tools instead of executing them manually, which can be time-consuming and prone to human error. By automating repetitive and routine tests, teams can focus their resources on more complex scenarios that require human insight and judgment. This efficiency allows for more frequent testing cycles, leading to quicker detection of defects and improved overall software quality.

While the other options may contain some elements related to testing, they do not accurately reflect the primary goal of automation testing. For instance, replacing all human testers is not feasible or desirable since human judgment is invaluable for exploratory testing and understanding user experience. Additionally, automation does not focus exclusively on user interface testing; it can be applied to various types of testing, including backend and API tests. Developing testing tools is a part of the automation process but is more of a means to an end rather than the primary goal itself.
