Functions

isLeftOf(Object? expected) → Matcher

Returns a matcher that matches if the actual object is of type Left and the underlying value is equal (for ==) to the expected value.

isRightOf(Object? expected) → Matcher

Returns a matcher that matches if the actual object is of type Right and the underlying value is equal (for ==) to the expected value.

isSomeOf(Object expected) → Matcher

Matcher that matches with a Some instance whose underlying value is equal to expected. Equality is tested with ==
