Exception 如何使用Vstest.console.exe和Moq避免序列化异常警告

我有一个.NET3.5项目和相应的单元测试项目

首先，由于VS 2013的更新，我无法再使用MSTest运行测试项目。我了解到

vstest.console.exe

是执行测试的新的首选方式

尽管如此，在使用

vstest.console.exe

执行550个单元测试的测试运行期间，所有这些测试都成功，我的控制台收到垃圾邮件，其中有许多异常：

我不知道我做错了什么。 我只能猜测，因为测试是在隔离模式下执行的（可能是因为.NET Framework 3.5），所以它需要在应用程序域之间传输一些对象，而这里出现了这些异常

我的问题是: 为什么找不到组件？Moq.dll就在我的单元测试程序集旁边。在测试运行期间，如何防止出现这数百条异常消息

更新：

我被要求同时运行fusion logger，它给了我以下信息：

现在，我问它为什么不使用我的测试项目提供的程序集。

---

我无法将

Moq.dll

复制到这些路径中的任何一个，因为我在同一个测试运行中运行了多个测试项目，这些测试项目使用了某些程序集的不同版本，并且我只能在此处提供一个特定版本。

我在生成计算机上收到了类似的警告。原因原来是在单元测试执行期间抛出了MockExceptions（即使在我的例子中，所有测试都成功了，因为异步等待的奇怪性）

---

识别这些异常的诀窍是“调试”单元测试，而不是“运行”（右键单击并选择“在项目级别调试所选测试”）。修复这些MockException为我消除了构建警告。希望这有帮助。

好的，我发现了问题

---

似乎在Moq NuGet包中，lib\net35\文件夹中的Moq.dll是针对.NET 4构建的dll，当测试在.NET 3.5环境中运行时，无法加载该dll。

问题是此测试项目不再与MSTest一起运行，也不再在VS中运行。执行测试的唯一方法是使用

vstest.console.exe

，因此我无法调试测试，因为测试运行程序将在VS中立即退出，而不运行任何测试。我也遇到了同样的问题。如上所述调试测试表明存在与应用MockBehavior.Strict相关的问题，但没有设置Dispose方法（当然是一次性对象）。让我烦恼的是，在这种情况下，测试本应失败，但似乎成功了。因此，这些警告似乎不应被忽视。
