在BadImageFormatException上运行NUnit测试时引发的TeamCity

Question

我有一个使用NUnit 2.6.3使用.Net 4.5的单元测试项目。但是在teamcity构建步骤配置中，我只有运行时4.0可用(即使我的解决方案的其他组件是针对4.5编译的)，并且当我运行我的单元测试时，我得到了以下异常：

    [Step 8/9] System.ArgumentException: Specified NUnit error running tests in '[SANITIZED].UnitTest.dll' assembly

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.

能帮我配置这些单元测试吗？

Answer 1

基于堆栈跟踪和NUnit发行说明，我的印象是问题不是针对v4.0平台的NUnit 2.6.3。

这似乎更可能是NUnit测试运行程序的bitness的一个问题，在您的工作中，这个问题是x64：

NUnit runner运行时为v4.0.30319，x64

如果MSIL编译的测试程序集试图加载某些x86库或类似的内容，则可以抛出x86。

只要将TeamCity作业的配置更改为使用32位NUnit运行程序(.NET运行时v4.0，x86)，就可以解决这个问题。
