Исключение BadImageFormatException при запуске тестов NUnit на TeamCity

Question

У меня есть проект модульного тестирования с использованием NUnit 2.6.3 с использованием .Net 4.5. Но в конфигурации шага TeamCity сборки у меня только во время выполнения 4.0 доступны (даже если другие компоненты моего раствора компилировать против 4,5), и когда я бег моего модульного тестирования я получаю следующее исключение:

[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.

Любую идею, чтобы помочь мне настроить эти модульные тесты?

Answer 1

На основе stacktrace и NUnit release notes мое впечатление, что проблема заключается в том, что проблема не с платформой NUnit 2.6.3 для платформы v4.0.

Это скорее, как представляется, проблема с разрядностью тест бегун NUnit, который в своей работе является 64:

NUnit бегун выполнения является v4.0.30319, x64

BadImageFormatException может быть затем выброшена, если ваша сборка MSIL скомпилированных тестов пытается загрузить некоторую библиотеку x86 или аналогично.

Простое изменение конфигурации задания TeamCity для использования 32-разрядного бегуна NUnit (.NET runtime v4.0, x86) должно устранить проблему.
