I tried recently to use NAnt (beta 0.86.2962.0) to run some unit tests compiled with the last stable version of NUnit (v2.4.8) without any success.
The error I get is the following :
[nunit2] Assembly "C:\Dev\MySample\bin\tests\My.Sample.Tests.dll" contains no tests.
Of course, the assembly contains tests that I can run from any runner, like NUnit one, TestDriven or Resharper. I would like to use <nunit2> task, and not directly the <exec> one, but I'm wondering if it is still possible, even using app.config files to bind assembly versions.
