Nunit tests are not found on tfs 2013 although NUnit test adapter package is used

I have a simple application and Nunit unit test project with 2 tests to test that app. I've managed to have unit tests discovered and run locally in Visual studio 2013 but when trying to build application and run these unit tests on TFS 2013 test runner does not find tests ( both projects are built successfully -) - getting message

No test found. Make sure that installed test discoverers & executors, platform & framework version settings are appropriate and try again.

I 've added "NUnit adapter with framework" package to Unit tests project according to answer in this question and committed changes to the TFS. Unit tests projects is successfully built but still no tests are found

Test dll fits the ***Test*.dll...

Why no tests are found? HOw I can make sure Test Ruuner ia aware about NUnit test adapter?

Any help will be highly appreciated.
