c# - NUnit 单元测试有 "ExpectedException"但仍然因异常而失败

Question

我有一个单元测试失败，因为 System.ArgumentException 被抛出，尽管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。

Answer 1

你试过断言语法吗？

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