Well, it's not that it's not always running.
I've got two VS2008 solutions. SP1. Current version of Resharper
One was branched off of the other. I'll call these main and sustainment -- sustainment was created off of main, and changes there are merged back in to main. No 3rd party unit tests involved.
If I load the sustainment solution, testrunner works fine. I can run a test in a session and it runs. I can debug.
If I load the main solution, where I'm wanting to do most of my work, it never runs, it just stays gray. It builds, , tests go to Pending, but they go back to gray. If I debug, VS switches to debug mode, and then drops out quickly.
If I run tests out of Visual Studio directly, they work.
And -- the main solution was working a while back.
Something's got to have changed that's preventing it from working, but I don't know where to look to see any meaningful output. I've tried turning off the shadow-copy but that had no effect.
I'd love to be able to just go look at a log file somewhere and see what it's running up against. I'm about to pull down code from 2-3 months ago and see if it starts working, then work my way forward binary-search-like.
But if anyone has any ideas, I'd be glad to look there first.
