Unit Test executes for a very long time

Question

Hi,

I have a solution with 400+ unit tests, I tried to execute this through command line MSTest.exe it executed in 2-3 minutes. But when I had configured this to a TFS build, the solution compiles and builds properly but the test cases are executing for a longer time... even after 24 hours of execution it still doesnt end... Please let me know how to troubleshoot this issue

Thanks

Arun

Answer 1

Hi Arun,

  Here are the possible reasons.

1. The tests are might NOT be returning/quitting or waiting for a process to complete
2. If the tests are connecting to external applications, you might need to check the windows firewall settings on the build machine to verify whether the calls are being blocked.
3. You could enable logging on MSTest.exe to investigate more. I have blogged the details steps http://my2centsontfs.blogspot.com/2012/03/enabling-logging-on-mstestexe.html
