What is a benefit of using test automation in software development?

Using test automation in software development offers significant benefits, one of which is ensuring consistency and repeatability of tests. This means that automated tests can be executed in the same way every time, eliminating variations that might occur with manual testing. Consistency is crucial in identifying defects and ensuring that new code changes do not break existing functionality. When tests are automated, developers can run the same set of tests across different environments and configurations, resulting in more reliable outcomes and allowing teams to focus on more complex testing aspects or new development tasks rather than repetitive manual testing.

The repetitive nature of manual testing can introduce human errors, such as forgetting certain steps or executing tests differently each time. Automated tests, on the other hand, are programmed to follow a specified set of procedures precisely. This leads to more thorough and dependable results, which is essential for maintaining the quality of the software over its development lifecycle. Additionally, automated tests can be triggered frequently, such as during continuous integration and continuous delivery (CI/CD) processes, ensuring that issues are caught early and addressed promptly.

Other options do not accurately reflect the advantages of test automation. For instance, increasing manual testing time is contrary to the goal of automation, which is aimed at reducing time spent on repetitive tasks. Moreover, while test
