Which of the following tools are required to allow for version control of test cases?

To allow for version control of test cases, the following tools are required:

A. Configuration management tool: This tool ensures that revisions are tracked and the latest versions of files are available. It helps in managing changes to test cases and keeps a record of all modifications made.

B. File merge utility: This tool allows multiple users to make changes to a single file. It helps in merging different versions of test cases and resolving conflicts that may arise when multiple users are working on the same file simultaneously.

C. Backup and restore utility: This tool ensures that test cases are available for reuse and are backed up and restored when needed. It helps in preventing data loss and ensures that previous versions of test cases can be retrieved if required.

D. Project tracking utility: This tool documents planned and actual tasks in creating and maintaining test cases. It helps in tracking the progress of test case development and provides visibility into the status of different tasks.

E. Change control utility: This tool ensures that proper procedures are followed when editing test cases. It helps in maintaining the integrity of test cases by enforcing a standardized process for making changes and ensuring that all changes are properly documented.

Therefore, the correct answer is A, B, C, D, E as all of these tools are required to allow for version control of test cases.
