I have two C# projects: a production project and NUnit tests for it.
I've recently added a test that causes a call into a registered COM
component, and now the test fails with a TypeLoadExcepti on when it
tries to load the interop assembly.
However, when I use the TestDriven.NET addin -- run via either
Debugger or In-Proc -- the test runs fine.
In trying to get a better idea of the problem, I found Suzanne Cook's
blog. I tried examining the Fusion log, but all it shows are attempts
to load nunit.uikit, not the interop assembly that the exception
complains about.
Catching the exception and probing a little, I see the following:
Could not load type TACGRAPHDOCLib. TGDocumentClass from assembly
Interop.TACGRAP HDOCLib, Version=1.0.0.0 , Culture=neutral ,
PublicKeyToken= null.
at AIM.Jvmf.CJvmfK 05_17Message.Ge tXml()
at JvmfUnitTests.K 0517GetXml.NoMo difierDuplicate s() in
...\k0517getxml .cs:line 41
No InnerException.
HRESULT = 0x80131522
I searched for other people reporting problems related to that hresult,
but the hits were VB issues, and none of the advice they got seemed
applicable to my situation.
I tried messing with the reference from the NUnit project to the COM
component, i.e., directly as a COM reference, browsing to the production
project's copy of the interop assembly, and cutting it out. No joy.
The fact that I can run the test without exception through TD.NET must
be a clue -- or at least a Scooby snack. I'd appreciate any guidance
the group might offer, even if it's only for ways to find more verbose
debug information.
Thanks,
Greg
