Instance Method Detail

def description : String #

Short text about the matcher's purpose. This explains what condition satisfies the matcher. The description is used when the one-liner syntax is used.


[View source]
def match(actual : Expression(T)) : MatchData forall T #

Actually performs the test against the expression.


[View source]
def negated_match(actual : Expression(T)) : MatchData forall T #

Performs the test against the expression, but inverted. A successful match with #match should normally fail for this method, and vice-versa.
