Instance Method Summary

::RSpec::Matchers::MatcherDelegator - Inherited

::RSpec::Matchers::Composable - Included

#&
#===

Delegates to #matches?.

#and

Creates a compound and expectation.

#description_of

Returns the description of the given object in a way that is aware of composed matchers.

#or

Creates a compound or expectation.

#values_match?

This provides a generic way to fuzzy-match an expected value against an actual value.

#|
#should_enumerate?

We should enumerate arrays as long as they are not recursive.

#surface_descriptions_in

Transforms the given data structure (typically a hash or array) into a new data structure that, when #inspect is called on it, will provide descriptions of any contained matchers rather than the normal #inspect output.

#unreadable_io?,
#with_matchers_cloned

Historically, a single matcher instance was only checked against a single value.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method in the class RSpec::Matchers::MatcherDelegator

Class Method Details

.interface_matches?(matcher) ⇒ Boolean

Note: #failure_message is part of the ::RSpec 3 protocol (paired with #failure_message_when_negated), so we don’t check for #failure_message here.
