Overview

Provides the implementation for RSpec::Matchers#be_between. Not intended to be instantiated directly.

Constant Summary

BaseMatcher - Inherited

UNDEFINED

Class Method Summary

BaseMatcher - Inherited

.matcher_name, .new,
.underscore

Borrowed from ActiveSupport.

Instance Attribute Summary

BaseMatcher - Inherited

#actual,
#diffable?

::RSpec::Matchers are not diffable by default.
#expected, #expects_call_stack_jump?, #matcher_name, #matcher_name=, #rescued_exception,
#supports_block_expectations?

Most matchers are value matchers (i.e. meant to work with ‘expect(value)`) rather than block matchers (i.e. meant to work with `expect { }`), so this defaults to false.
#supports_value_expectations?

BaseMatcher::StringEncodingFormatting - Included

#string_encoding_differs?

:nocov:

Instance Method Summary

BaseMatcher - Inherited

#actual_formatted,
#description

Generates a description using ::RSpec::Matchers::EnglishPhrasing.
#expected_formatted,
#match_unless_raises

Used to wrap a block of code that will indicate failure by raising one of the named exceptions.
#matches?

Indicates if the match is successful.

BaseMatcher::DefaultFailureMessages - Included

#failure_message

Provides a good generic failure message.
#failure_message_when_negated

Provides a good generic negative failure message.

BaseMatcher::StringEncodingFormatting - Included

#format_encoding

Formats a String’s encoding as a human readable string :nocov:

BaseMatcher::HashFormatting - Included

#improve_hash_formatting

‘{ :a => 5, :b => 2 }.inspect` produces:

::RSpec::Matchers::Composable - Included

#&

Alias for 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 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.
