c# - 无法使 nunit 测试异常起作用。使用 .net 2.0

Question

无论出于何种原因，我似乎无法获得正确的语法。 您如何进行以下测试。我只有一个简单的方法 TestThrowexception 并希望它通过 我在这里做错了什么？

           [TestFixture]
            public class ExceptionsTests
            {       
                [Test]
                public void When_calling_my_method_it_should_throw_an_exception()
                {
                //THIS DOES NOT WORK
                    Person person=new Person();

                    PersonException ex = Assert.Throws<PersonException>(delegate { person.ThrowPersonException(); },
                                                             Has.Property("Message").EqualTo("Test person Exception throw"));

                }
            }

            public class Person
            {
                public void ThrowException()
                {
                    throw new Exception("Test Exception thrown");
                }
                public void ThrowPersonException()
                {
                    throw new CustomerException("Test person Exception thrown");
                }


                public void ThrowArgumentException(string myParam)
                {
                    throw new ArgumentException("Argument Exception", myParam);
                }
            }
            [Serializable]
            public class PersonException : Exception
            {

                public PersonException()
                {
                }

                public PersonException(string message)
                    : base(message)
                {
                }

                public PersonException(string message, Exception inner)
                    : base(message, inner)
                {
                }

                protected PersonException(
                    SerializationInfo info,
                    StreamingContext context)
                    : base(info, context)
                {
                }
            }
        }

除了您抛出的异常类型的问题外，我会这样做。我认为它更具可读性。

[Test]
public void When_calling_my_method_it_should_throw_an_exception()
{
    Person person=new Person();
    PersonException ex = Assert.Throws<PersonException>(delegate { person.ThrowPersonException(); });
    Assert.That(ex.Message,Is.EqualTo("Test person Exception thrown");
}
