I'm running TFS 2012 with Microsoft Test Manager(MTM) for manual test design and test management. I've got this annoying issue, I can't seem to figure out. When I am building my test plans, creating tests and adding them to test suites -- MTM is adding an instance to the test cases I'm creating throughout other test suites in the same test plan.
For example, I have a test plan with 5 requirements, which I'll call Test Suites 1-5. Let's say I'm in test suite 3. To avoid creating each test from scratch, I copy and paste an instance of another test into test suite 3. This does not create a new test case, but basically just links to the test case instance for the one I copied over. I then right-click on the test case I copied over and click, "Create copy and add to suite". This must be done, since MTM does not create a new test case with just copying/pasting. So, that creates a new test case which I can then modify and save. Once I save it, that new test case is this added to Test Suite 3, but also Test Suite 1 and 2, but not 4 and 5. If I did this in test suite 5, it would be duplicated in all Test Suites 1-4. So it really makes so sense to me what MTM is doing here.
Any ideas? This will be a nightmare to clean up with features with a lot of reqs. Thanks for any help!
