Which of the following is an advantage of automation testing over manual testing?

Automation testing offers significant advantages, especially in terms of efficiency and scalability. One of the primary benefits is its ability to be reused across multiple projects. Once test scripts are created, they can be executed multiple times without the need for re-creation, which saves time and effort. This reusability is particularly advantageous in environments where software is being continuously integrated and delivered, as it allows teams to run regression tests easily on new versions or updates of the software.

In contrast, manual testing is inherently less efficient for repeated tasks since each test must be executed by a tester manually each time, which can lead to inconsistencies and increased labor costs. This is why automation testing is favored in scenarios that demand repeated execution and validation, allowing teams to focus their human resources on more complex testing scenarios that require critical thinking and problem-solving skills.
