问题
I have a unit test project using NUnit 2.6.3 using .Net 4.5. But in the teamcity build step configuration I only have runtime 4.0 available (even if other components of my solution are compile against 4.5) and when I run my unit test I get the following exception :
[Step 8/9] System.ArgumentException: Specified NUnit error running tests in '[SANITIZED].UnitTest.dll' assembly
Loading assembly is compiled for v4.0.30319, MSIL
NUnit runner runtime is v4.0.30319, x64
System.ArgumentException: A BadImageFormatException has been thrown while parsing the signature. This is likely due to lack of a generic context. Ensure genericTypeArguments and genericMethodArguments are provided and contain enough context. ---> System.BadImageFormatException: Could not load file or assembly '[SANITIZED]' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Any idea to help me to configure these unit tests ?
回答1:
Based on the stacktrace and NUnit release notes my impression is that the problem is not with NUnit 2.6.3 targeting v4.0 platform.
It more likely seems to be an issue with bitness of the NUnit test runner, which in your job is x64:
NUnit runner runtime is v4.0.30319, x64
The BadImageFormatException can be then thrown if your MSIL compiled test assembly is trying to load some x86 library or similarly.
Simply changing the configuration of your TeamCity job to use 32bit NUnit runner (.NET runtime v4.0, x86) should fix the issue.
