Using NUnit, I have 331 unit tests in the current solution. ReSharper can find 209 of them. I don't get the little yellow/green bubbles next to all of [Test] or [TestFixture] attributes. They don't show up in the Unit Test Explorer. The test fixtures all all public classes, and nothing else seems amiss.
NUnit finds/runs them all 331 from outside the solution, and TestDriven finds/runs them all 331 from inside the solution.
What I've tried so far:
Browsing thru the unit test projects, trying to run all from the test fixture.
The Unit Test Explorer.
"Show All Unit Tests" from the Unit Test Session.
Menu: ReSharper, Unit Testing, Run All Unit Tests From Solution
Deleted the "_ReSharper.foo" directory, and the "foo.Resharper.user" file, hoping that would force ReSharper to re-evaluate the test count.
