Follow the steps below to start unlinking and deleting test cases in a user story.

How to unlink test cases in a user story:

1. Navigate to the Boards page in the sidebar.

Note: You can also access the user story via the Work Items page in the sidebar.

2. Open the user story where you want to unlink the test case.

3. Hover your mouse to the desired test case to be unlinked on the bottom right of the user story.

Notice how the ’x’ icon appears as soon as you hover to the test case.

4. Click the ‘x’ icon beside the test case you want to delete.

The ’Save & Close’ button should be enabled after clicking the ’x’ icon.

After saving, you have successfully unlinked the test case. However, the test case is only unlinked to the user story but still exists as a test case in Azure DevOps.
