在TeamCity上運行NUnit測試時拋出BadImageFormatException

Question

我使用.Net 4.5使用NUnit 2.6.3進行單元測試項目。 但是在teamcity構建步驟配置中我只有運行時4.0可用（即使我的解決方案的其他組件是針對4.5編譯的），當我運行單元測試時，我得到以下異常：

    [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.

有什么想法幫我配置這些單元測試嗎？

Answer 1

根據stacktrace和NUnit發行說明，我的印象是問題不在於NUnit 2.6.3定位v4.0平台。

它似乎更像是NUnit測試運行器的位數問題，在你的工作中是x64：

NUnit runner runtime是v4.0.30319，x64

如果您的MSIL編譯的測試程序集試圖加載某些x86庫或類似的，則可以拋出BadImageFormatException 。

只需更改TeamCity作業的配置以使用32位NUnit運行程序（.NET運行時v4.0，x86）即可解決此問題。
