I'm using TeamCity Professional 5.1.5 (build 13602). I have a project which builds a Visual Studio 2010 solution using the Visual Studio (sln) runner, and also runs unit tests using NUnit 2.5.5. The project seems to compile fine, but the Team City NUnit runner crashes. The build log's attached.
It seems to me that NUnit is looking for my test dll in the wrong place (the TeamCity plugin directory).
For the record, I tried telling NUnit the location of the test dll using a path relative to the solution path and an absolute path (in the "Run Tests from" text box), but I got the same error.
