Instance methods
description
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.
match(actual : Expression(T)) : MatchData forall T
Actually performs the test against the expression.
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.
