Thanks for reporting this problem and accept my apologies for any inconvenience JustCode have caused you. I see that this problem is quite common so we must take care of it as soon as possible.
We have one known issue with NUnit which could be the cause of your problems. JustCode's test runner does not recognize correctly unit tests that use attribute inheritance. Meaning, that if you have TestFixture attribute on some base class and Test attributes on methods of a derived class, the test runner won't show those tests. The problem appeared a bit too late and we weren't able to fix it for the release. However we consider it with highest priority and will fix it for the next internal build we release.
In case the issue I described is not your case, it would be of great help for us if you could provide some more info for the problem. For starters try and create a simple test class with test method and see if JustCode will show that method in the test window.
Thanks a lot for the collaboration in advance.
