What is the purpose of a bug tracking tool in automation testing?

The purpose of a bug tracking tool in automation testing is to manage and document defects identified during testing. Such tools serve as a centralized system where testers can report, track, and prioritize bugs or issues that arise during the testing phases. This allows teams to collaborate efficiently, ensuring that defects are not only recorded but also followed through to resolution.

By documenting each bug, including its status, severity, and steps to reproduce, the tracking tool facilitates effective communication among team members, encouraging a systematic approach to problem-solving. This is essential in maintaining the overall quality of the software, as it helps teams to identify patterns in bugs and improve the development process over time.

The other options focus on areas that are unrelated to the primary function of a bug tracking tool. Implementing code changes directly, improving user interface design, or creating test scripts automatically fall outside the scope of bug management and are typically handled by different tools or methodologies within the software development lifecycle.
