Memory leaks

Issue 1

When you repeatedly open and close a work item that includes a webpage control in the template, the Test Manager process leaks memory.

Issue 2

Consider the following scenario:
  • You have a manual test process that is in several steps in Test Manager.

In this scenario, the process leaks memory, and the process may grow by hundreds of megabytes (MB).

Issue 3

When you run a test case in Test Manager while an instance of an application is running, the MTM.exe process leaks memory and may grow by hundreds of megabytes. For example, you run a test case in Test Manager while an instance of a Visual Studio 2010 is running.

Issue 4

When you run concurrent operations for several hours in Test Manager, you may receive an Out-of-Memory exception, and then Test Manager crashes.

Issue 5

When you add many test cases to a test suite, a memory leak occurs.

Other issues

Issue 1

After you close the Test Case Manager page, the test cases continue to be downloaded from Microsoft Team Foundation Server (TFS).

Issue 2

When you run a test case, and when the Assigned To field in the test case is empty, you receive the following error message:
Object reference not set to instance of object.

Additionally, the test case returns no data.

Issue 3

Test Manager does not have a feature to let you type a fractional number in a Double data type field of a work item.

Issue 4

An automated test case from a build-drop path requires a long time to load.
