Debugging Typemock test case in Visual Studio 2015 throws TypeMockException

In Visual Studio 2015, when I attempt to debug a test that uses Typemock (and I use the Visual Studio Test Explorer, not Typemock's SmartRunner), on the first call to a Typemock method I get the following exception:

TypeMock.TypeMockException occurred HResult=-2146233088
Message=
*** Typemock Isolator is currently disabled. Enable using the following:

  • Within Visual Studio:
    • Use Typemock Smart Runner
    • For other runners, Choose Typemock Menu and click "Integrate with Other Runners"
      • To run Typemock Isolator as part of an automated process you can:
      • run tests via TMockRunner.exe command line tool
      • use 'TypeMockStart' tasks for MSBuild or NAnt

I've followed the instructions and verified that:

  • Typemock is enabled
  • I already have "Enable Mocking integration" checked in the settings

Also,

  • The test runs properly when I choose "Run Selected Tests". I only get the exception when I choose "Debug Selected Tests"
  • Prior to Visual Studio 2015, I did not get this exception during debugging.

Question: What is causing this problem and how do I fix it?

Solution

  • The IntelliTrace functionality does not work with Typemock. Disabling IntelliTrace in the Visual Studio options (Options->IntelliTrace->General->Enable IntelliTrace) works around the issue.
