struct Spectator::Matchers::HaveMatcher(ExpectedType)

Overview

Matcher that tests whether a value, such as a String or Array, matches one or more values. For a String, the includes? method is used. Otherwise, it expects an Enumerable and iterates over each item until === is true.

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 #

Entrypoint for the matcher, forwards to the correct method for string or enumerable.


[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.
