I have been head down into writing some tests and debugging them in Visual Studio 2008, and every other time I would get see that my test would get a yellow triangle with an exclamation sign and it said “Not Executed”. On clicking on the link for the error, the following error message is displayed:
Code coverage collection error: The Visual Studio performance and coverage logging engine is already running on the computer. Therefore, the test run cannot continue. Close the pending performance or code coverage session and then rerun the tests.
Although it was beyond me why Visual Studio performance engine would run but it was easy to just find it in Task Manager and just kill it.
Problem solved for now….
