即使存在ExpectedException属性，Nunit Test也会以异常失败

Question

我有这个简单的测试

 [Test]
 [ExpectedException(typeof(Exception))]
 public void Test2()
 {
     throw new Exception();
 }

因为我知道这个测试失败了因为我被指示看到这样的异常，但它失败并出现此错误

Test Name:  Test2
Test FullName:  Framework.Tests.Service.BaseServiceTest.Test2
Test Source:    c:\Framework.Tests\Service\BaseServiceTest.cs : line 75
Test Outcome:   Failed
Test Duration:  0:00:00.189

Result StackTrace:  at Framework.Tests.Service.BaseServiceTest.Test2() in c:\Framework.Tests\Service\BaseServiceTest.cs:line 76
Result Message: System.Exception : Exception of type 'System.Exception' was thrown.

我也尝试过其他类型的异常，结果是相同的
