Hi,
Thanks for posting!
There isn't any way you can manually flag tests with a particular status in NCrunch. The only way for a test to be considered passing is for it to pass.
If the tests are never supposed to be run in NCrunch, I recommend just
ignoring them using the options in the Tests Window. This will set them to a status of 'Ignored' which won't be considered failing.
To reset NCrunch's recorded status of all your tests, just close your IDE and delete the "_NCrunch_" directory inside your solution directory. The next time you start up NCrunch for this solution, all remembered test data and code coverage will be cleared, but your settings will still be intact.
Cheers,
Remco
