Hi,

How do you execute this NUnit test from TestComplete?

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 https://support.smartbear.com/testcomplete/docs/working-with/integration/unit-test-frameworks/nunit/...

Hi

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.
