I am trying to run unit tests on a project, but the tests will not load. Every test has a "Load failed" message. This is the stack trace printed when I attempt to run a single test.

ERROR [2011-10-08 16:28:02Z]: System.NullReferenceException: Object reference not set to an instance of an object

Try 2.8 It contains some bugfixes in the unit test addin.
(btw. which mono version/distro do you use?)

Reopen, if it happens again.

Thank you for pointing me in that direction.  I am running Ubuntu 11.10, which comes with Monodevelop 2.6 by default.  I had to build from source since there's no Monodevelop 2.8 package available for Oneiric, but that was no trouble at all.  Upgrading to Monodevelop 2.8 nicely resolves the problems I mentioned in the original bug report.
