确定代码运行作为单元测试的一部分 [英] Determine if code is running as part of a unit test

问题描述

我有一个单元测试（NUnit的）。许多层向下调用堆栈，如果它是通过单元测试运行的方法将失败。

I have a unit test (nUnit). Many layers down the call stack a method will fail if it is running via a unit test.

在理想情况下，你会使用类似嘲讽设置，这种方法是根据不同的对象。关于但这是第三方代码，我不能这样做，如果没有大量的工作。

Ideally you would use something like mocking to setup the object that this method is depending on but this is 3rd party code and I can't do that without a lot of work.

我不希望安装NUnit的具体方法 - 有太多的水平这里和做单元测试的一个好办法。

I don't want setup nUnit specific methods - there are too many levels here and its a poor way of doing unit test.

相反，我想要做的就是在调用栈

Instead what I would like to do is to add something like this deep down in the call stack

#IF DEBUG // Unit tests only included in debug build
if (IsRunningInUnitTest)
   {
   // Do some setup to avoid error
   }
#endif

因此，任何想法左右如何写IsRunningInUnitTest？

So any ideas about how to write IsRunningInUnitTest?

PS我深知，这不是伟大的设计，但我的认为的它比其它更好。

P.S. I am fully aware that this is not great design, but I think its better than the alternatives.

推荐答案

我已经这样做过 - 我只好抱着我的鼻子，而我做到了，但我做到了。实用主义次教条主义每次。当然，如果有是的可重构，以避免它一个很好的方法，这将是巨大的。

I've done this before - I had to hold my nose while I did it, but I did it. Pragmatism beats dogmatism every time. Of course, if there is a nice way you can refactor to avoid it, that would be great.

基本上，我有一个UnitTestDetector类检查NUnit的框架组件是否在当前的AppDomain加载。它只需做一次，然后缓存结果。难看，但简单而有效的。

Basically I had a "UnitTestDetector" class which checked whether the NUnit framework assembly was loaded in the current AppDomain. It only needed to do this once, then cache the result. Ugly, but simple and effective.
