::RSpec::Matchers::Composable - Included

#&

Alias for Matchers::Composable#and.
#===

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.
#|

Alias for Matchers::Composable#or.
#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
