NCrunch doesn't mark lines as covered by tests, but they are

Question

I have just started using NCrunch and have some classes where the markers show there is no coverage, but I have tests which NCrunch is running successfully.

When I edit the class (just add a space) the markers go green for a short while, then return to black. Why might this be?

Answer 1

I had this happen today and just a simple VS restart fixed it. You can also try resync button which is the 6th from the left of the NCrunch Tests window.

Answer 2

I think I had the same problem based on the description. It also appeared to affect coverage stats as well as the visual markers. I was running NCrunch 1.39.15b on VS2010. Re-syncing and reloading VS2010 did not fix it. I eventually uninstalled NCrunch and upgraded to 1.41.0.50 and the problem went away. It might have been a bug in NCrunch, but I'm not sure. At any rate, try upgrading your NCrunch installation and see if that works.
