# Flags

`ShouldHaveFlag` allows you to assert whether an object is an enum and has a flag specified.

Conversely `ShouldNotHaveFlag` allows you to assert the opposite; that an object is an enum but does not have a flag specified.

## ShouldHaveFlag

```cs
var actual = TestEnum.FlagTwo;
var value = TestEnum.FlagOne;
actual.ShouldHaveFlag(value);
```
