我有一个带有相应单元测试项目的 .NET 3.5 项目。

首先,自从 VS 2013 更新以来,我无法再使用 MSTest 运行测试项目。我了解到vstest.console.exe是执行测试的新首选方式。

vstest.console.exe尽管如此,在执行 550 个单元测试的测试运行期间,它们都成功了,我的控制台收到了大量以下异常的垃圾邮件:

我不知道我做错了什么。我只能猜测,因为执行了测试in Isolation模式(可能是.NET Framework 3.5的原因),它需要在应用程序域之间传输一些对象,而这里会出现这些异常。

我的问题是:为什么找不到程序集?Moq.dll 就在我的单元测试程序集旁边。在测试运行期间,我可以做些什么来防止这数百条异常消息?

更新:

我被要求同时运行融合记录器,它给了我以下信息:

LOG: This bind starts in default load context.

现在,我在问为什么它不使用我的测试项目提供的程序集。我无法将 复制Moq.dll到这些路径中的任何一个,因为我在同一测试运行中运行多个测试项目,这些测试项目使用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。

我在构建机器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(即使在我的情况下,所有测试都成功,因为 async-await 怪异)。

识别这些异常的技巧是“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选定的测试)。修复这些 MockExceptions 为我摆脱了构建警告。希望这可以帮助。

好的,我发现了问题。

在 Moq NuGet 包中,lib\net35\ 文件夹中的 Moq.dll 似乎是针对 .NET 4 构建的 dll,并且在 .NET 3.5 环境中运行测试时无法加载。
