We run our unit tests under a Jenkins build server, via nant.
To run the tests we use the nunit-console as our code is compiled as .NET 4.
<exec program="${nunit-console.exe}"
workingdir="${CCNetArtifactDirectory}"
commandline="${shortFileName} /xml:${resultFileName} /nologo /nodots /nothread /domain=Single /framework:net-4.0"/>
We are using NUnit 2.5.10.
However, intermittently we see this exception, which stops our builds:
Unhandled Exception:

I am running into the exact same problem for our unit tests under the NUnit runner on a Bamboo build server. The log shows the exact same error as above.
I was also using local Bamboo variables for the directory path to the DLL to test. The occurances of this error went down considerably when I explicitly indicated the path to the DLL, however the variables are still in there (as they are defined at the Project level and I'm using them for other Plans/Jobs), and the log does show them as environmental variable substitutions when calling NUnit (not that I necessarily think this is the cause, just pointing out similarities).
