NUnit 单元测试有“ExpectedException”但仍然因异常而失败

我有一个单元测试失败，因为抛出了 System.ArgumentException，即使我期待它并且它是故意的行为 - 我错过了什么？

[Test]
[ExpectedException(typeof(ArgumentException), ExpectedMessage = "Seconds from midnight cannot be more than 86400 in 010100712386401000000012")]
public void TestParsingCustomReferenceWithInValidSecondsFromMidnight()
{
    // I am expecting this method to throw an ArgumentException:
    CustomReference.Parse("010100712386401000000012");
}

我也尝试过不设置 ExpectedMessage - 没有区别。

I have a unit test that is failing because a System.ArgumentException is being thrown, even though I am expecting it and it's deliberate behaviour - what have I missed?

[Test]
[ExpectedException(typeof(ArgumentException), ExpectedMessage = "Seconds from midnight cannot be more than 86400 in 010100712386401000000012")]
public void TestParsingCustomReferenceWithInValidSecondsFromMidnight()
{
    // I am expecting this method to throw an ArgumentException:
    CustomReference.Parse("010100712386401000000012");
}

I've also tried without the ExpectedMessage being set - no difference.

您尝试过断言语法吗？

Assert.Throws<ArgumentException>(
    () => CustomReference.Parse("010100712386401000000012"),
    "Seconds from midnight cannot be more than 86400 in 010100712386401000000012"
);

Have you tried the assertion syntax?

Assert.Throws<ArgumentException>(
    () => CustomReference.Parse("010100712386401000000012"),
    "Seconds from midnight cannot be more than 86400 in 010100712386401000000012"
);

预期的消息是否正确？这与 CustomReference.Parse(string) 抛出的消息完全相同吗？例如，它不是 NUnit 控制台中显示的内容。

我不知道这行不通的另一个原因。您使用什么版本的 NUnit？

如果你这样做会发生什么？

[TestFixture]
public class CustomReferenceTests
{
    [Test]
    [ExpectedException(typeof(ArgumentException))]
    public void TestParsingCustomReferenceWithInValidSecondsFromMidnight()
    {
        // I am expecting this method to throw an ArgumentException:
        CustomReference.Parse("010100712386401000000012");
    }

    [Test]
    [ExpectedException(typeof(ArgumentException), ExpectedMessage = "Seconds from midnight cannot be more than 86400 in 010100712386401000000012")]
    public void TestParsingCustomReferenceWithInValidSecondsFromMidnightWithExpectedMessage()
    {
        // I am expecting this method to throw an ArgumentException:
        CustomReference.Parse("010100712386401000000012");
    }
}

public class CustomReference
{
    public static void Parse(string s)
    {
        throw new ArgumentException("Seconds from midnight cannot be more than 86400 in 010100712386401000000012");
    }
}

What happens if you do this?

[TestFixture]
public class CustomReferenceTests
{
    [Test]
    [ExpectedException(typeof(ArgumentException))]
    public void TestParsingCustomReferenceWithInValidSecondsFromMidnight()
    {
        // I am expecting this method to throw an ArgumentException:
        CustomReference.Parse("010100712386401000000012");
    }

    [Test]
    [ExpectedException(typeof(ArgumentException), ExpectedMessage = "Seconds from midnight cannot be more than 86400 in 010100712386401000000012")]
    public void TestParsingCustomReferenceWithInValidSecondsFromMidnightWithExpectedMessage()
    {
        // I am expecting this method to throw an ArgumentException:
        CustomReference.Parse("010100712386401000000012");
    }
}

public class CustomReference
{
    public static void Parse(string s)
    {
        throw new ArgumentException("Seconds from midnight cannot be more than 86400 in 010100712386401000000012");
    }
}
