Which of the following practices aids in effective management of test case versions?

Using a centralized repository for test case storage is essential for effective management of test case versions because it allows teams to maintain a single source of truth for all test artifacts. This approach facilitates collaboration among team members, ensuring that everyone works with the latest versions of test cases, thus reducing the chances of discrepancies or duplicated efforts. Centralized repositories often include version control features, which allow team members to track changes to test cases over time, revert to previous versions if necessary, and easily manage updates as requirements evolve.

This practice enhances traceability and accountability, making it easier to audit changes, understand testing coverage, and ensure consistency across different testing environments. The centralized approach also simplifies the process of sharing test cases with stakeholders and integrating automated test management tools into the development workflow.

In contrast, options like regularly updating the frequency of test executions or limiting the number of test cases do not directly address version management and may lead to inefficient testing practices. Running test cases manually can introduce human error and may not provide the necessary control over test case evolution. Thus, a centralized repository is the most effective strategy for managing test case versions comprehensively.
