How do you have the NUnit test set up within TestComplete?  A screenshot of the configuration option will probably be helpful in diagnosing the problem.   Reference

Why automate?  I do automated testing because there's only so much a human being can do and remain healthy.  Sleep is a requirement.  So, while people sleep, automation that I create does what I've described above in order to make sure that nothing gets past the final defense of the testing group.

You use NUnit2 command Line parameters.
NUnit3 can't use this parameters

Could you check a version of TestComplete(Only TestComplete 14.10 supports NUnit3)

Thanks, I was using Test Complete 12.6 version so I uninstalled all the Nunit 3 references and installed Nunit 2.7 references. It is working fine now.
