在 TeamCity 上运行 NUnit 测试时抛出 BadImageFormatException [英] BadImageFormatException thrown when running NUnit tests on TeamCity

问题描述

我有一个使用 NUnit 2.6.3 和 .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，我得到以下异常:

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.

有什么想法可以帮助我配置这些单元测试吗?

Any idea to help me to configure these unit tests ?

推荐答案

基于 stacktrace 和 NUnit 发行说明 我的印象是问题出在 不是针对 v4.0 平台的 NUnit 2.6.3.

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.

这更有可能是 NUnit 测试运行程序的位数问题，在您的工作中是 x64:

It more likely seems to be an issue with bitness of the NUnit test runner, which in your job is x64:

NUnit runner 运行时是 v4.0.30319，x64

NUnit runner runtime is v4.0.30319, x64

如果您的 MSIL 编译的测试程序集试图加载某些 x86 库或类似的库，则可以抛出 BadImageFormatException.

The BadImageFormatException can be then thrown if your MSIL compiled test assembly is trying to load some x86 library or similarly.

只需将 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)即可解决该问题.

Simply changing the configuration of your TeamCity job to use 32bit NUnit runner (.NET runtime v4.0, x86) should fix the issue.
