I would like to get a perfect test documentation and I miss a field when linked test cases to concrete tests between TFS and Visual Studio.
I search for a while but could not find any relevant documentation.
How to set / get set the field "Automated test type" in linked automation tab of a TFS test case description:
I hope this may help you. In MSDN you can find how to associate a test method with respective test case.
When you know the identifier of the work item for the test case:
If you are using Visual Studio 2017 or later, follow these steps to associate your tests.
If the Test Explorer window is not displayed, open it from the Test | Windows menu.
If your tests are not displayed in Test Explorer, build the solution.
In Test Explorer, select the test method you want to associate and choose Associate to Test Case.
In the dialog that opens, type the test case identifier and choose Add Association, then choose Save.
The dialog shows a list of test cases currently associated with the selected test method. You cannot associate more than one test method with a test case, but you can associate a test method with more than one test case.
