Feature Request: enumValue.Should().BeDefined()

[aureole82]

Can you add an extension for this:

// Act.
var dayOfWeek = (DayOfWeek)999;

// Assert.
dayOfWeek.Should().BeOneOf(Enum.GetValues<DayOfWeek>());
Enum.IsDefined(dayOfWeek).Should().BeTrue();
// suggested: dayOfWeek.Should().BeDefined();

---

I use FluentAssertions Version="6.5.1".

I can confirm that this is not present and agree that it would be a nice addition to EnumAssertions.

Here's a more formal proposal of the APIs to add.

EnumAssertions<TEnum, TAssertions>.BeDefined(string because = "", params object[] becauseArgs);
EnumAssertions<TEnum, TAssertions>.NotBeDefined(string because = "", params object[] becauseArgs);

If you don't mind.. I would take this..
