如何使用Vstest.console.exe和Moq避免SerializationException警告

2019年8月4日 280次阅读

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.

尽管如此,在运行550个UnitTests的vstest.console.exe测试运行期间,所有这些都成功了,我的控制台被垃圾邮件带来了很多例外情况：

Warning: System.Runtime.Serialization.SerializationException: Unable to find assembly 'Moq, Version=4.2.1402.2112, Culture=neutral, PublicKeyToken=69f491c39445e920'.

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),它需要在应用程序域之间传输一些对象,这里出现这些异常.

我的问题是：
为什么组装不能找到？ Moq.dll就在我的单元测试组件旁边.在测试运行期间,我该怎么做才能防止这些数百个异常消息？

更新：

我被要求一起运行融合记录器,它给了我这个信息：

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Assemblies.
我无法将Moq.dll复制到任何这些路径,因为我在同一个测试运行中运行多个测试项目,使用不同版本的某些程序集,我只能在这里提供一个特定版本.

最佳答案 我在构建机器上收到了类似的警告.原因是在单元测试执行期间抛出MockExceptions(即使在我的情况下,所有测试都成功,因为异步 – 等待怪异).

识别这些异常的技巧是“调试”单元测试而不是“运行”(右键单击并选择项目级别的调试选定测试).修复这些MockExceptions摆脱了我的构建警告.希望这可以帮助.
