Enum comparison does not work as expected

[BenGeba]

Description

According to the documentation, with the standard method Should().Be(), the Enum comparison should work the same as the .NET Implementation Enum.Equals() method.

However, with the following code this does not work for me.

public enum MyEnumResult
{
    Successfully,
    Failed
}

public enum MySecondEnumResult
{
    Successfully,
    AnotherValue,
    Failed
}

[Test]
public void MyTest()
{
    MyEnumResult result = _sut.Get(_id);

    //This works as expected
    result.Should().Be(MyEnumResult.Successfully);
    //This works also, but should not
    result.Should().Be(MySecondEnumResult.Successfully);
}

Although the two enums are not of the same type, the test does not fail. Apparently only the underlying value is tested, but not the type.

Versions

• Fluent Assertions version is 5.10.3
• .NET framework 4.7.2

Thanks for highlighting this inconsistency of Be for enums.
If you use HaveFlag instead, this should work as expected.

In the upcoming v6 this should be more visible due to #1375.
We also have discussions about reworking this further, see #1204.
Another case of inconsistency is #1208
