class RSpec::Core::Configuration

Stores runtime configuration information.

Configuration options are loaded from `~/.rspec`, `.rspec`, `.rspec-local`, command line switches, and the `SPEC_OPTS` environment variable (listed in lowest to highest precedence; for example, an option in `~/.rspec` can be overridden by an option in `.rspec-local`).

@example Standard settings

RSpec.configure do |c|
  c.drb          = true
  c.drb_port     = 1234
  c.default_path = 'behavior'
end

@example Hooks

RSpec.configure do |c|
  c.before(:suite)   { establish_connection }
  c.before(:example) { log_in_as :authorized }
  c.around(:example) { |ex| Database.transaction(&ex) }
end

Public Instance Methods

add_formatter(formatter_to_use, *paths) click to toggle source

@overload #add_formatter(formatter)

Adds a formatter to the formatters collection. `formatter` can be a string representing any of the built-in formatters (see `built_in_formatter`), or a custom formatter class.

### Note

For internal purposes, `add_formatter` also accepts the name of a class and paths to use for output streams, but you should consider that a private api that may change at any time without notice.

# File lib/rspec/core/configuration.rb, line 705
def add_formatter(formatter_to_use, *paths)
  paths << output_stream if paths.empty?
  formatter_loader.add formatter_to_use, *paths
end
Also aliased as: formatter=
add_setting(name, opts={}) click to toggle source

@overload ::add_setting(name) @overload ::add_setting(name, opts) @option opts [Symbol] :default

Set a default value for the generated getter and predicate methods:

    add_setting(:foo, :default => "default value")

@option opts [Symbol] :alias_with

Use `:alias_with` to alias the setter, getter, and predicate to
another name, or names:

    add_setting(:foo, :alias_with => :bar)
    add_setting(:foo, :alias_with => [:bar, :baz])

Adds a custom setting to the RSpec.configuration object.

RSpec.configuration.add_setting :foo

Used internally and by extension frameworks like rspec-rails, so they can add config settings that are domain specific. For example:

RSpec.configure do |c|
  c.add_setting :use_transactional_fixtures,
    :default => true,
    :alias_with => :use_transactional_examples
end

`add_setting` creates three methods on the configuration object, a setter, a getter, and a predicate:

RSpec.configuration.foo=(value)
RSpec.configuration.foo
RSpec.configuration.foo? # Returns true if foo returns anything but nil or false.
# File lib/rspec/core/configuration.rb, line 400
def add_setting(name, opts={})
  default = opts.delete(:default)
  (class << self; self; end).class_exec do
    add_setting(name, opts)
  end
  __send__("#{name}=", default) if default
end
after(*args, &block) click to toggle source

Defines a `after` hook. See {Hooks#after} for full docs.

This method differs from {Hooks#after} in only one way: it supports the `:suite` scope. Hooks with the `:suite` scope will be run once after the last example of the entire suite is executed.

@see append_after @see before @see prepend_before

Calls superclass method RSpec::Core::Hooks#after
# File lib/rspec/core/configuration.rb, line 1495
def after(*args, &block)
  handle_suite_hook(args, @after_suite_hooks, :unshift,
                    Hooks::AfterHook, block) || super(*args, &block)
end
Also aliased as: prepend_after
alias_example_group_to(new_name, *args) click to toggle source

Creates a method that defines an example group with the provided metadata. Can be used to define example group/metadata shortcuts.

@example

RSpec.configure do |config|
  config.alias_example_group_to :describe_model, :type => :model
end

shared_context_for "model tests", :type => :model do
  # define common model test helper methods, `let` declarations, etc
end

# This lets you do this:

RSpec.describe_model User do
end

# ... which is the equivalent of

RSpec.describe User, :type => :model do
end

@note The defined aliased will also be added to the top level

(e.g. `main` and from within modules) if
`expose_dsl_globally` is set to true.

@see alias_example_to @see expose_dsl_globally=

# File lib/rspec/core/configuration.rb, line 870
def alias_example_group_to(new_name, *args)
  extra_options = Metadata.build_hash_from(args)
  RSpec::Core::ExampleGroup.define_example_group_method(new_name, extra_options)
end
alias_example_to(name, *args) click to toggle source

Creates a method that delegates to `example` including the submitted `args`. Used internally to add variants of `example` like `pending`: @param name [String] example name alias @param args [Array<Symbol>, Hash] metadata for the generated example

@note The specific example alias below (`pending`) is already

defined for you.

@note Use with caution. This extends the language used in your

specs, but does not add any additional documentation. We use this
in RSpec to define methods like `focus` and `xit`, but we also add
docs for those methods.

@example

RSpec.configure do |config|
  config.alias_example_to :pending, :pending => true
end

# This lets you do this:

describe Thing do
  pending "does something" do
    thing = Thing.new
  end
end

# ... which is the equivalent of

describe Thing do
  it "does something", :pending => true do
    thing = Thing.new
  end
end
# File lib/rspec/core/configuration.rb, line 838
def alias_example_to(name, *args)
  extra_options = Metadata.build_hash_from(args)
  RSpec::Core::ExampleGroup.define_example_method(name, extra_options)
end
alias_it_behaves_like_to(new_name, report_label='') click to toggle source

Define an alias for it_should_behave_like that allows different language (like “it_has_behavior” or “it_behaves_like”) to be employed when including shared examples.

@example

RSpec.configure do |config|
  config.alias_it_behaves_like_to(:it_has_behavior, 'has behavior:')
end

# allows the user to include a shared example group like:

describe Entity do
  it_has_behavior 'sortability' do
    let(:sortable) { Entity.new }
  end
end

# which is reported in the output as:
# Entity
#   has behavior: sortability
#     ...sortability examples here

@note Use with caution. This extends the language used in your

specs, but does not add any additional documentation. We use this
in RSpec to define `it_should_behave_like` (for backward
compatibility), but we also add docs for that method.
# File lib/rspec/core/configuration.rb, line 901
def alias_it_behaves_like_to(new_name, report_label='')
  RSpec::Core::ExampleGroup.define_nested_shared_group_method(new_name, report_label)
end
alias_it_should_behave_like_to(new_name, report_label='')
append_after(*args, &block) click to toggle source

Adds `block` to the end of the list of `after` blocks in the same scope (`:example`, `:context`, or `:suite`), in contrast to {#after}, which adds the hook to the start of the list.

See {Hooks#after} for full `after` hook docs.

This method differs from {Hooks#append_after} in only one way: it supports the `:suite` scope. Hooks with the `:suite` scope will be run once after the last example of the entire suite is executed.

@see append_after @see before @see prepend_before

Calls superclass method RSpec::Core::Hooks#append_after
# File lib/rspec/core/configuration.rb, line 1514
def append_after(*args, &block)
  handle_suite_hook(args, @after_suite_hooks, :push,
                    Hooks::AfterHook, block) || super(*args, &block)
end
append_before(*args, &block)

@private

# File lib/rspec/core/configuration.rb, line 1447
def apply_derived_metadata_to(metadata)
  @derived_metadata_blocks.items_for(metadata).each do |block|
    block.call(metadata)
  end
end
backtrace_exclusion_patterns() click to toggle source

Regexps used to exclude lines from backtraces.

Excludes lines from ruby (and jruby) source, installed gems, anything in any “bin” directory, and any of the RSpec libs (outside gem installs) by default.

You can modify the list via the getter, or replace it with the setter.

To override this behaviour and display a full backtrace, use `–backtrace` on the command line, in a `.rspec` file, or in the `rspec_options` attribute of RSpec's rake task.

# File lib/rspec/core/configuration.rb, line 436
def backtrace_exclusion_patterns
  @backtrace_formatter.exclusion_patterns
end
backtrace_exclusion_patterns=(patterns) click to toggle source

Set regular expressions used to exclude lines in backtrace. @param patterns [Regexp] set the backtrace exlusion pattern

# File lib/rspec/core/configuration.rb, line 442
def backtrace_exclusion_patterns=(patterns)
  @backtrace_formatter.exclusion_patterns = patterns
end
backtrace_inclusion_patterns() click to toggle source

Regexps used to include lines in backtraces.

Defaults to [Regexp.new Dir.getwd].

Lines that match an exclusion and an inclusion pattern will be included.

You can modify the list via the getter, or replace it with the setter.

# File lib/rspec/core/configuration.rb, line 454
def backtrace_inclusion_patterns
  @backtrace_formatter.inclusion_patterns
end
backtrace_inclusion_patterns=(patterns) click to toggle source

# File lib/rspec/core/configuration.rb, line 460
def backtrace_inclusion_patterns=(patterns)
  @backtrace_formatter.inclusion_patterns = patterns
end
before(*args, &block) click to toggle source

Defines a `before` hook. See {Hooks#before} for full docs.

This method differs from {Hooks#before} in only one way: it supports the `:suite` scope. Hooks with the `:suite` scope will be run once before the first example of the entire suite is executed.

@see prepend_before @see after @see append_after

Calls superclass method RSpec::Core::Hooks#before

    @color = false
  else
    @color = true
  end
end
color_enabled?(output=output_stream) click to toggle source

Check if color is enabled for a particular output. @param output [IO] an output stream to use, defaults to the current

%x`output_stream`

@return [Boolean]

# File lib/rspec/core/configuration.rb, line 656
def color_enabled?(output=output_stream)

# File lib/rspec/core/configuration.rb, line 713
def default_formatter
  formatter_loader.default_formatter
end
default_formatter=(value) click to toggle source

Sets a fallback formatter to use if none other has been set.

@example

end
# File lib/rspec/core/configuration.rb, line 724
def default_formatter=(value)
  formatter_loader.default_formatter = value
end
define_derived_metadata(*filters, &block) click to toggle source

Defines a callback that can assign derived metadata values.

@param filters [Array<Symbol>, Hash] metadata filters that determine

which example or group metadata hashes the callback will be triggered
for. If none are given, the callback will be run against the metadata
hashes of all groups and examples.

@yieldparam metadata [Hash] original metadata hash from an example or

group. Mutate this in your block as needed.

@example

RSpec.configure do |config|
  # Tag all groups and examples in the spec/unit directory with
  # :type => :unit
  config.define_derived_metadata(:file_path => %r{/spec/unit/}) do |metadata|
    metadata[:type] = :unit
  end
end
# File lib/rspec/core/configuration.rb, line 1441
def define_derived_metadata(*filters, &block)
  meta = Metadata.build_hash_from(filters, :warn_about_example_group_filtering)
  @derived_metadata_blocks.append(block, meta)
end
deprecation_stream=(value) click to toggle source

Determines where deprecation warnings are printed. @param value [IO, String] IO to write to or filename to write to

# File lib/rspec/core/configuration.rb, line 145
def deprecation_stream=(value)
  if @reporter && !value.equal?(@deprecation_stream)
    warn "RSpec's reporter has already been initialized with "              "#{deprecation_stream.inspect} as the deprecation stream, so your change to "             "`deprecation_stream` will be ignored.

  else
    @deprecation_stream = value
  end
end
disable_monkey_patching!() click to toggle source

Enables zero monkey patching mode for RSpec. It removes monkey patching of the top-level DSL methods (`describe`, `shared_examples_for`, etc) onto `main` and `Module`, instead requiring you to prefix these methods with `RSpec.`. It enables expect-only syntax for rspec-mocks and rspec-expectations. It simply disables monkey patching on whatever pieces of RSpec the user is using.

@note It configures rspec-mocks and rspec-expectations only

if the user is using those (either explicitly or implicitly
by not setting `mock_with` or `expect_with` to anything else).

@note If the user uses this options with `mock_with :mocha`

(or similiar) they will still have monkey patching active
in their test environment from mocha.

@example

# It disables all monkey patching.
RSpec.configure do |config|
  config.disable_monkey_patching!
end

# Is an equivalent to
RSpec.configure do |config|
  config.expose_dsl_globally = false

  config.mock_with :rspec do |mocks|
    mocks.syntax = :expect
    mocks.patch_marshal_to_support_partial_doubles = false
  end

  config.mock_with :rspec do |expectations|

  conditionally_disable_mocks_monkey_patching
  conditionally_disable_expectations_monkey_patching
end
exclude_pattern=(value) click to toggle source

Set pattern to match files to exclude. @attr value [String] the filename pattern to exclude spec files by

# File lib/rspec/core/configuration.rb, line 213
def exclude_pattern=(value)
  update_pattern_attr :exclude_pattern, value
end
exclusion_filter() click to toggle source

Returns the `exclusion_filter`. If none has been set, returns an empty hash.

# File lib/rspec/core/configuration.rb, line 1016
def exclusion_filter
  filter_manager.exclusions
end
exclusion_filter=(filter) click to toggle source

Clears and reassigns the `exclusion_filter`. Set to `nil` if you don't want any exclusion filter at all.

### Warning

This overrides any exclusion filters/tags set on the command line or in configuration files.

# File lib/rspec/core/configuration.rb, line 1009
def exclusion_filter=(filter)
  meta = Metadata.build_hash_from([filter], :warn_about_example_group_filtering)
  filter_manager.exclude_only meta
end
expect_with(*frameworks) { |first.configuration| ... } click to toggle source

Sets the expectation framework module(s) to be included in each example group.

`frameworks` can be `:rspec`, `:test_unit`, `:minitest`, a custom module, or any combination thereof:

config.expect_with :rspec
config.expect_with :test_unit
config.expect_with :minitest
config.expect_with :rspec, :minitest
config.expect_with OtherExpectationFramework

RSpec will translate `:rspec`, `:minitest`, and `:test_unit` into the appropriate modules.

## Configuration

If the module responds to `configuration`, `expect_with` will yield the `configuration` object if given a block:

config.expect_with OtherExpectationFramework do |custom_config|
  custom_config.custom_setting = true
end
# File lib/rspec/core/configuration.rb, line 596
def expect_with(*frameworks)
  modules = frameworks.map do |framework|
    case framework
    when Module

  end

  if block_given?
    raise "expect_with only accepts a block with a single argument. "                  "Call expect_with #{modules.length} times, "                  "once with each argument, instead." if modules.length > 1
    raise "#{modules.first} must respond to `configuration` so that "                  "expect_with can yield it." unless modules.first.respond_to?(:configuration)
    yield modules.first.configuration
  end

  @expectation_frameworks.push(*modules)
end
expectation_framework=(framework) click to toggle source

Delegates to #expect_with(framework).

# File lib/rspec/core/configuration.rb, line 569
def expectation_framework=(framework)
  expect_with(framework)
end
expectation_frameworks() click to toggle source

Returns the configured expectation framework adapter module(s)

    end
  end
  @expectation_frameworks
end
expose_current_running_example_as(method_name) click to toggle source

Exposes the current running example via the named helper method. RSpec 2.x exposed this via `example`, but in RSpec 3.0, the example is instead exposed via an arg yielded to `it`, `before`, `let`, etc. However, some extension gems (such as Capybara) depend on the RSpec 2.x's `example` method, so this config option can be used to maintain compatibility.

@param method_name [Symbol] the name of the helper method

@example

RSpec.configure do |rspec|
  rspec.expose_current_running_example_as :example
end

describe MyClass do
  before do
    # `example` can be used here because of the above config.
    do_something if example.metadata[:type] == "foo"
  end
end
# File lib/rspec/core/configuration.rb, line 1352
def expose_current_running_example_as(method_name)

end
expose_dsl_globally=(value) click to toggle source

Use this to expose the core RSpec DSL via `Module` and the `main` object. It will be set automatically but you can override it to remove the DSL. Default: true

extend(mod, *filters) click to toggle source

Tells RSpec to extend example groups with `mod`. Methods defined in `mod` are exposed to example groups (not examples). Use `filters` to constrain the groups to extend.

Similar to `include`, but behavior is added to example groups, which are classes, rather than the examples, which are instances of those classes.

@example

module UiHelpers
  def run_in_browser
    # ...
  end
end

RSpec.configure do |config|
  config.extend(UiHelpers, :type => :request)
end

describe "edit profile", :type => :request do
  run_in_browser

  it "does stuff in the client" do
    # ...

filter_gems_from_backtrace(*gem_names) click to toggle source

Adds {#backtrace_exclusion_patterns} that will filter lines from the named gems from backtraces.

@param gem_names [Array<String>] Names of the gems to filter

@example

RSpec.configure do |config|
  config.filter_gems_from_backtrace "rack", "rake"
end

@note The patterns this adds will match the named gems in their common

locations (e.g. system gems, vendored with bundler, installed as a
:git dependency with bundler, etc) but is not guaranteed to work for
all possible gem locations. For example, if you have the gem source
in a directory with a completely unrelated name, and use bundler's
:path option, this will not filter it.
# File lib/rspec/core/configuration.rb, line 480
def filter_gems_from_backtrace(*gem_names)
  gem_names.each do |name|
    @backtrace_formatter.filter_gem(name)
  end
end
filter_run(*args)
filter_run_excluding(*args) click to toggle source

Adds key/value pairs to the `exclusion_filter`. If `args` includes any symbols that are not part of the hash, each symbol is treated as a key in the hash with the value `true`.

### Note

Filters set using this method can be overridden from the command line or config files (e.g. `.rspec`).

@example

# Given this declaration.
describe "something", :foo => 'bar' do
  # ...
end

# Any of the following will exclude that group.
config.filter_run_excluding :foo => 'bar'
config.filter_run_excluding :foo => /^ba/
config.filter_run_excluding :foo => lambda {|v| v == 'bar'}
config.filter_run_excluding :foo => lambda {|v,m| m[:foo] == 'bar'}

# Given a proc with an arity of 1, the lambda is passed the value
# related to the key, e.g.
config.filter_run_excluding :foo => lambda {|v| v == 'bar'}

# Given a proc with an arity of 2, the lambda is passed the value
# related to the key, and the metadata itself e.g.

end
include(mod, *filters) click to toggle source

Tells RSpec to include `mod` in example groups. Methods defined in `mod` are exposed to examples (not example groups). Use `filters` to constrain the groups or examples in which to include the module.

@example

module AuthenticationHelpers
  def login_as(user)
    # ...
  end
end

module UserHelpers
  def users(username)
    # ...
  end
end

RSpec.configure do |config|
  config.include(UserHelpers) # included in all modules
  config.include(AuthenticationHelpers, :type => :request)
end

describe "edit profile", :type => :request do
  it "can be viewed by owning user" do
    login_as users(:jdoe)
    get "/profiles/jdoe"
    assert_select ".username", :text => 'jdoe'
  end
end

@note Filtered module inclusions can also be applied to

individual examples that have matching metadata. Just like
Ruby's object model is that every object has a singleton class
which has only a single instance, RSpec's model is that every
example has a singleton example group containing just the one
example.

@see extend @see prepend

# File lib/rspec/core/configuration.rb, line 1060

# File lib/rspec/core/configuration.rb, line 421
def mock_framework=(framework)
  mock_with framework
end
mock_with(framework) { |configuration| ... } click to toggle source

Sets the mock framework adapter module.

`framework` can be a Symbol or a Module.

Given any of `:rspec`, `:mocha`, `:flexmock`, or `:rr`, configures the named framework.

Given `:nothing`, configures no framework. Use this if you don't use any mocking framework to save a little bit of overhead.

Given a Module, includes that module in every example group. The module should adhere to RSpec's mock framework adapter API:

setup_mocks_for_rspec
  - called before each example

verify_mocks_for_rspec
  - called after each example if the example hasn't yet failed.
    Framework should raise an exception when expectations fail

teardown_mocks_for_rspec
  - called after verify_mocks_for_rspec (even if there are errors)

If the module responds to `configuration` and `mock_with` receives a block, it will yield the configuration object to the block e.g.

config.mock_with OtherMockFrameworkAdapter do |mod_config|
  mod_config.custom_setting = true
end
# File lib/rspec/core/configuration.rb, line 524
def mock_with(framework)

prepend(mod, *filters) click to toggle source

Tells RSpec to prepend example groups with `mod`. Methods defined in `mod` are exposed to examples (not example groups). Use `filters` to constrain the groups in which to prepend the module.

Similar to `include`, but module is included before the example group's class in the ancestor chain.

@example

module OverrideMod
  def override_me
    "overridden"

end

prepend_before(*args, &block) click to toggle source

Adds `block` to the start of the list of `before` blocks in the same scope (`:example`, `:context`, or `:suite`), in contrast to {#before}, which adds the hook to the end of the list.

See {Hooks#before} for full `before` hook docs.

This method differs from {Hooks#prepend_before} in only one way: it supports the `:suite` scope. Hooks with the `:suite` scope will be run once before the first example of the entire suite is executed.
