Which statement best describes automated testing?

Automated testing is best described as the process that involves using software tools to execute tests. This method leverages various testing frameworks and tools to run predefined tests automatically, allowing for faster and more efficient testing cycles. By utilizing scripts and automation frameworks, teams can repeatedly execute test cases, which significantly increases testing throughput and helps maintain consistency in test execution.

Automated testing is particularly effective for regression testing, performance testing, and repetitive tasks that would be time-consuming and error-prone if executed manually. It enables teams to focus on more complex testing scenarios and exploratory testing, rather than spending extensive time on routine tasks.

The other statements do not accurately reflect the essence of automated testing. For instance, stating that it is only performed manually misrepresents the core function of automation. Claiming it is limited to functional testing ignores its application in other testing types, such as performance or load testing. Furthermore, while automation can assist in improving efficiency, it is not intended to entirely replace human testers; human oversight and intuition remain important in testing workflows.
