I have been having some problems with the test debugger in VS10. All tests are running without error, but when debugging it aborts when I try to read the object data. Afterwards, this error is displayed in the summary: Test host process exited unexpectedly.
I’m unable to see anymore details about the error. How do I access/generate test-log files? Or, even better: Has anyone experienced a similar problem? And found a solution?
Additional information:
The runtime-test-data is available on objects from same libary assembly, it’s just one class I can’t get access to in runtime mode. If I use breakpoints at:
- every line that affects the object: – I can see the runtime-data and the test passes
- only one place: – the test will abort and no data is visible
- no breakpoints: – the test runs and passes.
The test used to work fine until recently. Just before the problem occurred when I made some solution changes with dividing the projects into solution folders. I didn’t make any changes that should affect the code. Moving the projects back to their original folder don’t solve the problem, So I wonder – Is this a bug in Visual Studio itself?
Here is what I’ve tried so far:
- Rebuilding and cleaning the solution.
- Closing Visual Studio and rebooting my system.
- Installing VS10 Service Pack 1
- Reinstalling Visual Studio 10
- Testing on VS10 Ultimate and Premium
- Removing and regenerating solutions files
- Removing all break points
- TraceAndTestImpact/Local.testsettings: Testing
Timeout > timeoutand setting abort to 30 minutes. - TraceAndTestImpact/Local.testsettings:
Unit Test > Assemblyfolders defined - TraceAndTestImpact/Local.testsettings:
Deployment > Enable deploymentdirectories and files
How can I fix this? Any suggestions are welcome.
What’s most likely happening here is that a property, local which is being evaluated in the locals or autos window is causing a side effect in the running process which leads to the failure. To verify this you should turn off automatic property evaluation
