struct Spectator::Matchers::StartWithMatcher(ExpectedType)

Overview

Matcher that tests whether a value, such as a String or Array, starts with a value. The starts_with? method is used if it's defined on the actual type. Otherwise, it is treated as an Enumerable and the first value is compared against.

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 : TestExpression(T)) : MatchData forall T #

Actually performs the test against the expression.


[View source]
def negated_match(actual : TestExpression(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.
