Sure, here is an example of test case management:

Define the scope of testing: Determine the areas of the application that need to be tested and the testing requirements.
Create test cases: Develop test cases that cover all the requirements and functionalities. Include test steps, expected results, and actual results.
Prioritize test cases: Prioritize test cases based on their importance and impact on the application.
Assign test cases: Assign test cases to the team members responsible for testing.
Execute test cases: Execute the test cases and record the actual results.
Track defects: Document any defects found during testing and track their status.
Report test results: Generate reports that summarize the test results and provide an overview of the application's quality.
Review and improve: Review the test cases and process to identify areas for improvement.
Retest: Retest any defects that were fixed to ensure they have been resolved.
Sign off: Obtain sign-off from stakeholders to confirm that the application has been tested and is ready for release
