Question

我有很多实例和属性，我想使用XUnit进行验证。

myInstance.SomeProperty1.Should().HaveCount(2);
myInstance.SomeProperty2.Should().HaveCount(2);
[...]
myInstance.SomePropertyN.Should().HaveCount(2);

当此断言失败时，它们会抛出以下异常

Xunit.Sdk.XunitException
Expected collection to contain 2 item(s), but found 0.
   at FluentAssertions.Execution.XUnit2TestFramework.Throw(String message)
   at FluentAssertions.Execution.AssertionScope.FailWith(String message, Object[] args)
   at FluentAssertions.Collections.SelfReferencingCollectionAssertions`2.HaveCount(Int32 expected, String because, Object[] becauseArgs)
   at [...]

   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
   at Xunit.Sdk.ExceptionAggregator.<RunAsync>d__9.MoveNext()

到目前为止，一切都很好。但是，如何使异常更有意义？我想查看断言失败的属性的名称。

问题是，这是相当大的对象，测试的分解通常要花费一些时间。知道测试失败的属性可以加快我的测试过程。预先感谢！

如何使XunitExceptions更有意义？
