Welcome to Microsoft Q&A
Hello @Nev Percy I hope you are doing well.
If a Test Case shows "No test results found" in its execution history, it usually means that Azure DevOps can no longer associate any test results with that Test Case. This can happen for several reasons:
- Test results have been deleted manually or removed as part of a retention policy.
- The associated Test Run was deleted, which also removes the execution history linked to its Test Cases.
- The Test Case was moved, cloned, or recreated, resulting in a new Work Item ID that is no longer associated with the original test results.
- The test results belong to a different project or test plan, and you're viewing the Test Case in a different context.
- Permissions may prevent you from viewing the underlying Test Runs or Test Results.
Recommended checks
- Verify whether the corresponding Test Run still exists under Test Plans > Runs.
- Check if any retention policies have been configured that automatically remove old test results.
- Confirm that you're viewing the correct Project, Test Plan, and Test Suite.
- Review the Audit Logs (if available) to determine whether any Test Runs or Test Results were recently deleted.
- If the results disappeared unexpectedly without any administrative changes, check the Azure DevOps Service Health dashboard to rule out a service issue.
