Class: RSpec::Rails::Matchers::HaveHttpStatus::GenericStatus Private

Do not use. This class is for internal use only.

Overview

Provides an implementation for ‘have_http_status` matching against ActionDispatch::TestResponse http status category queries.

Not intended to be instantiated directly.

Examples:

expect(response).to have_http_status(:success)
expect(response).to have_http_status(:error)
expect(response).to have_http_status(:missing)
expect(response).to have_http_status(:redirect)

Class Method Summary

.matcher_name, .new,
.underscore

Borrowed from ActiveSupport.

Instance Attribute Summary

::RSpec::Rails::Matchers::BaseMatcher - Inherited

#actual,
#diffable?

::RSpec::Rails::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.

Instance Method Summary

::RSpec::Rails::Matchers::HaveHttpStatus - Included

#invalid_response_type_message,
#as_test_response

Conversion function to coerce the provided object into an ‘ActionDispatch::TestResponse`.

::RSpec::Rails::Matchers::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.
#assert_ivars, #present_ivars

::RSpec::Rails::Matchers::BaseMatcher::DefaultFailureMessages - Included

#failure_message

Provides a good generic failure message.
#failure_message_when_negated

Provides a good generic negative failure message.

::RSpec::Rails::Matchers::BaseMatcher::HashFormatting - Included

#improve_hash_formatting

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

::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.
