  # of the suite during a bisection. Your choices are:
  #
  #   - `:shell`: Performs a spec run by shelling out, booting RSpec and your
  #     application environment each time. This runner is the most widely
  #     compatible runner, but is not as fast. On platforms that do not
  #     support forking, this is the default.
  #   - `:fork`: Pre-boots RSpec and your application environment in a parent
  #     process, and then forks a child process for each spec run. This runner
  #     tends to be significantly faster than the `:shell` runner but cannot
  #     be used in some situations. On platforms that support forking, this
  #     is the default. If you use this runner, you should ensure that all
  #     of your one-time setup logic goes in a `before(:suite)` hook instead
  #     of getting run at the top-level of a file loaded by `--require`.

  # Seed for random ordering (default: generated randomly each run).
  #
  # When you run specs with `--order random`, RSpec generates a random seed
  # for the randomization and prints it to the `output_stream` (assuming
  # you're using RSpec's built-in formatters). If you discover an ordering
  # dependency (i.e. examples fail intermittently depending on order), set
  # this (on Configuration or on the command line with `--seed`) to run
  # using the same seed while you debug the issue.
  #
  # We recommend, actually, that you use the command line approach so you
  # don't accidentally leave the seed encoded.
  #
  # source://rspec-core//lib/rspec/core/configuration.rb#1647
  def seed(*args, &block); end

  # Sets the seed value and sets the default global ordering to random.

  # Configures how RSpec treats metadata passed as part of a shared example
  # group definition. For example, given this shared example group definition:
  #
  #     RSpec.shared_context "uses DB", :db => true do
  #       around(:example) do |ex|
  #         MyORM.transaction(:rollback => true, &ex)
  #       end
  #     end
  #
  # ...there are two ways RSpec can treat the `:db => true` metadata, each
  # of which has a corresponding config option:
  #
  # 1. `:trigger_inclusion`: this shared context will be implicitly included
  #    in any groups (or examples) that have `:db => true` metadata.
  # 2. `:apply_to_host_groups`: the metadata will be inherited by the metadata
  #    hash of all host groups and examples.
  #
  # `:trigger_inclusion` is the legacy behavior from before RSpec 3.5 but should
  # be considered deprecated. Instead, you can explicitly include a group with
  # `include_context`:
  #
  #     RSpec.describe "My model" do
  #       include_context "uses DB"
  #     end
  #
  # ...or you can configure RSpec to include the context based on matching metadata
  # using an API that mirrors configured module inclusion:
  #
  #     RSpec.configure do |rspec|
  #       rspec.include_context "uses DB", :db => true
  #     end
  #
  # `:apply_to_host_groups` is a new feature of RSpec 3.5 and will be the only
  # supported behavior in RSpec 4.

# The object returned by `it "does something"` is an instance of Example,
# which serves as a wrapper for an instance of the ExampleGroup in which it
# is declared.
#
# Example group bodies (e.g. `describe` or `context` blocks) are evaluated
# in the context of a new subclass of ExampleGroup. Individual examples are
# evaluated in the context of an instance of the specific ExampleGroup
# subclass to which they belong.

# Besides the class methods defined here, there are other interesting macros
# defined in {Hooks}, {MemoizedHelpers::ClassMethods} and
# {SharedExampleGroup}. There are additional instance methods available to
# your examples defined in {MemoizedHelpers} and {Pending}.

# ## Built-in Formatters
#
# * progress (default) - Prints dots for passing examples, `F` for failures, `*`
#                        for pending.
# * documentation - Prints the docstrings passed to `describe` and `it` methods
#                   (and their aliases).
# * html
# * json - Useful for archiving data for subsequent analysis.
#
# The progress formatter is the default, but you can choose any one or more of
# the other formatters by passing with the `--format` (or `-f` for short)
# command-line option, e.g.
#
#     rspec --format documentation
#
# You can also send the output of multiple formatters to different streams, e.g.
#
#     rspec --format documentation --format html --out results.html
#
# This example sends the output of the documentation formatter to `$stdout`, and
# the output of the html formatter to results.html.
#
# ## Custom Formatters
#
# You can tell RSpec to use a custom formatter by passing its path and name to
# the `rspec` command. For example, if you define MyCustomFormatter in
# path/to/my_custom_formatter.rb, you would type this command:
#
#     rspec --require path/to/my_custom_formatter.rb --format MyCustomFormatter
#
# The reporter calls every formatter with this protocol:
#
# * To start
#   * `start(StartNotification)`
# * Once per example group
#   * `example_group_started(GroupNotification)`
# * Once per example
#   * `example_started(ExampleNotification)`
# * One of these per example, depending on outcome
#   * `example_passed(ExampleNotification)`
#   * `example_failed(FailedExampleNotification)`
#   * `example_pending(ExampleNotification)`
# * Optionally at any time
#   * `message(MessageNotification)`
# * At the end of the suite
#   * `stop(ExamplesNotification)`
#   * `start_dump(NullNotification)`
#   * `dump_pending(ExamplesNotification)`
#   * `dump_failures(ExamplesNotification)`
#   * `dump_summary(SummaryNotification)`
#   * `seed(SeedNotification)`
#   * `close(NullNotification)`
#
# Only the notifications to which you subscribe your formatter will be called
# on your formatter. To subscribe your formatter use:
# `RSpec::Core::Formatters#register` e.g.
#
# `RSpec::Core::Formatters.register FormatterClassName, :example_passed, :example_failed`
#
# We recommend you implement the methods yourself; for simplicity we provide the
# default formatter output via our notification objects but if you prefer you
# can subclass `RSpec::Core::Formatters::BaseTextFormatter` and override the
# methods you wish to enhance.

# Provides `before`, `after` and `around` hooks as a means of
# supporting common setup and teardown. This module is extended

# or `context` block and included in {Configuration}, making them
# available off of the configuration object to define global setup
# or teardown logic.
#
# source://rspec-core//lib/rspec/core/hooks.rb#9
module RSpec::Core::Hooks
  # Declare a block of code to be run after each example (using `:example`)
  # or once after all examples n the context (using `:context`). See
  # {#before} for more information about ordering.
  #
  # ### Exceptions
  #
  # `after` hooks are guaranteed to run even when there are exceptions in
  # `before` hooks or examples. When an exception is raised in an after
  # block, the exception is captured for later reporting, and subsequent
  # `after` blocks are run.
  #
  # ### Order
  #
  # `after` hooks are stored in three scopes, which are run in order:
  # `:example`, `:context`, and `:suite`. They can also be declared in
  # several different places: `RSpec.configure`, a parent group, the current
  # group. They are run in the following order:
  #
  #     after(:example) # Declared in the current group.
  #     after(:example) # Declared in a parent group.
  #     after(:example) # Declared in RSpec.configure.
  #     after(:context) # Declared in the current group.
  #     after(:context) # Declared in a parent group.
  #     after(:context) # Declared in RSpec.configure.
  #     after(:suite)   # Declared in RSpec.configure.
  #
  # This is the reverse of the order in which `before` hooks are run.
  # Similarly, if more than one `after` is declared within any example
  # group, they are run in reverse order of that in which they are declared.
  # Also `around` hooks will run after any `after` example hooks are
  # invoked but before any `after` context hooks.
  #
  # @api public
  # @note The `:example` and `:context` scopes are also available as
  #   `:each` and `:all`, respectively. Use whichever you prefer.
  # @note The `:suite` scope is only supported for hooks registered on
  #   `RSpec.configuration` since they exist independently of any
  #   example or example group.

  # Declare a block of code to be run before each example (using `:example`)
  # or once before any example (using `:context`). These are usually
  # declared directly in the {ExampleGroup} to which they apply, but they
  # can also be shared across multiple groups.
  #
  # You can also use `before(:suite)` to run a block of code before any
  # example groups are run. This should be declared in {RSpec.configure}.
  #
  # Instance variables declared in `before(:example)` or `before(:context)`
  # are accessible within each example.
  #
  # ### Order
  #
  # `before` hooks are stored in three scopes, which are run in order:
  # `:suite`, `:context`, and `:example`. They can also be declared in
  # several different places: `RSpec.configure`, a parent group, the current
  # group. They are run in the following order:
  #
  #     before(:suite)    # Declared in RSpec.configure.
  #     before(:context)  # Declared in RSpec.configure.
  #     before(:context)  # Declared in a parent group.
  #     before(:context)  # Declared in the current group.
  #     before(:example)  # Declared in RSpec.configure.
  #     before(:example)  # Declared in a parent group.
  #     before(:example)  # Declared in the current group.
  #
  # If more than one `before` is declared within any one example group, they
  # are run in the order in which they are declared. Any `around` hooks will
  # execute after `before` context hooks but before any `before` example
  # hook regardless of where they are declared.
  #
  # ### Conditions
  #
  # When you add a conditions hash to `before(:example)` or
  # `before(:context)`, RSpec will only apply that hook to groups or
  # examples that match the conditions. e.g.
  #
  #     RSpec.configure do |config|
  #       config.before(:example, :authorized => true) do
  #         log_in_as :authorized_user
  #       end
  #     end
  #
  #     RSpec.describe Something, :authorized => true do
  #       # The before hook will run in before each example in this group.
  #     end
  #
  #     RSpec.describe SomethingElse do
  #       it "does something", :authorized => true do
  #         # The before hook will run before this example.
  #       end
  #
  #       it "does something else" do
  #         # The hook will not run before this example.
  #       end
  #     end
  #
  # Note that filtered config `:context` hooks can still 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.
  #
  # ### Warning: `before(:suite, :with => :conditions)`
  #
  # The conditions hash is used to match against specific examples. Since
  # `before(:suite)` is not run in relation to any specific example or
  # group, conditions passed along with `:suite` are effectively ignored.
  #
  # ### Exceptions
  #
  # When an exception is raised in a `before` block, RSpec skips any
  # subsequent `before` blocks and the example, but runs all of the
  # `after(:example)` and `after(:context)` hooks.
  #
  # ### Warning: implicit before blocks
  #
  # `before` hooks can also be declared in shared contexts which get
  # included implicitly either by you or by extension libraries. Since
  # RSpec runs these in the order in which they are declared within each
  # scope, load order matters, and can lead to confusing results when one
  # before block depends on state that is prepared in another before block
  # that gets run later.
  #
  # ### Warning: `before(:context)`
  #
  # It is very tempting to use `before(:context)` to speed things up, but we
  # recommend that you avoid this as there are a number of gotchas, as well
  # as things that simply don't work.
  #
  # #### Context
  #
  # `before(:context)` is run in an example that is generated to provide
  # group context for the block.
  #
  # #### Instance variables
  #
  # Instance variables declared in `before(:context)` are shared across all
  # the examples in the group. This means that each example can change the
  # state of a shared object, resulting in an ordering dependency that can
  # make it difficult to reason about failures.
  #
  # #### Unsupported RSpec constructs
  #
  # RSpec has several constructs that reset state between each example
  # automatically. These are not intended for use from within
  # `before(:context)`:
  #
  #   * `let` declarations
  #   * `subject` declarations
  #   * Any mocking, stubbing or test double declaration
  #
  # ### other frameworks
  #
  # Mock object frameworks and database transaction managers (like
  # ActiveRecord) are typically designed around the idea of setting up
  # before an example, running that one example, and then tearing down. This
  # means that mocks and stubs can (sometimes) be declared in
  # `before(:context)`, but get torn down before the first real example is
  # ever run.
  #
  # You _can_ create database-backed model objects in a `before(:context)`
  # in rspec-rails, but it will not be wrapped in a transaction for you, so
  # you are on your own to clean up in an `after(:context)` block.
  #
  # @api public
  # @example before(:example) declared in an {ExampleGroup}
  #   RSpec.describe Thing do
  #   before(:example) do
  #   @thing = Thing.new
  #   end
  #
  #   it "does something" do
  #   # Here you can access @thing.
  #   end
  #   end
  # @example before(:context) declared in an {ExampleGroup}
  #   RSpec.describe Parser do
  #   before(:context) do
  #   File.open(file_to_parse, 'w') do |f|
  #   f.write <<-CONTENT
  #   stuff in the file
  #   CONTENT
  #   end
  #   end
  #
  #   it "parses the file" do
  #   Parser.parse(file_to_parse)
  #   end
  #
  #   after(:context) do
  #   File.delete(file_to_parse)
  #   end
  #   end
  # @note The `:example` and `:context` scopes are also available as
  #   `:each` and `:all`, respectively. Use whichever you prefer.
  # @note The `:suite` scope is only supported for hooks registered on

  #
  # They are not a synonym for `before`/`after`.
  #
  # @api public
  # @note the syntax of `around` is similar to that of `before` and `after`
  #   but the semantics are quite different. `before` and `after` hooks are
  #   run in the context of the examples with which they are associated,
  #   whereas `around` hooks are actually responsible for running the

  # Declare a block of code to be run after each example (using `:example`)
  # or once after all examples n the context (using `:context`). See
  # {#before} for more information about ordering.
  #
  # ### Exceptions
  #
  # `after` hooks are guaranteed to run even when there are exceptions in
  # `before` hooks or examples. When an exception is raised in an after
  # block, the exception is captured for later reporting, and subsequent
  # `after` blocks are run.
  #
  # ### Order
  #
  # `after` hooks are stored in three scopes, which are run in order:
  # `:example`, `:context`, and `:suite`. They can also be declared in
  # several different places: `RSpec.configure`, a parent group, the current
  # group. They are run in the following order:
  #
  #     after(:example) # Declared in the current group.
  #     after(:example) # Declared in a parent group.
  #     after(:example) # Declared in RSpec.configure.
  #     after(:context) # Declared in the current group.
  #     after(:context) # Declared in a parent group.
  #     after(:context) # Declared in RSpec.configure.
  #     after(:suite)   # Declared in RSpec.configure.
  #
  # This is the reverse of the order in which `before` hooks are run.
  # Similarly, if more than one `after` is declared within any example
  # group, they are run in reverse order of that in which they are declared.
  # Also `around` hooks will run after any `after` example hooks are
  # invoked but before any `after` context hooks.
  #
  # @api public
  # @note The `:example` and `:context` scopes are also available as
  #   `:each` and `:all`, respectively. Use whichever you prefer.
  # @note The `:suite` scope is only supported for hooks registered on

# This provides the primary API used by other parts of rspec-core. By hiding all

# a hook is added. This allows us to avoid many object allocations for the common
# case of a group having no hooks.
#
# This is only possible because this interface provides a "tell, don't ask"-style

# Together with the example group metadata hash default block,
# provides backwards compatibility for the old `:example_group`
# key. In RSpec 2.x, the computed keys of a group's metadata
# were exposed from a nested subhash keyed by `[:example_group]`, and
# then the parent group's metadata was exposed by sub-subhash
# keyed by `[:example_group][:example_group]`.
#
# In RSpec 3, we reorganized this to that the computed keys are
# exposed directly of the group metadata hash (no nesting), and
# `:parent_example_group` returns the parent group's metadata.
#
# Maintaining backwards compatibility was difficult: we wanted
# `:example_group` to return an object that:
#
#   * Exposes the top-level metadata keys that used to be nested
#     under `:example_group`.
#   * Supports mutation (rspec-rails, for example, assigns
#     `metadata[:example_group][:described_class]` when you use
#     anonymous controller specs) such that changes are written
#     back to the top-level metadata hash.

  #   RSpec.describe Thing do

  #   # Second invocation, returns the memoized value.
  #   thing.should be_something
  #   end
  #   end
  # @note `let` _can_ enhance readability when used sparingly (1,2, or
  #   maybe 3 declarations) in any given example group, but that can
  #   quickly degrade with overuse. YMMV.
  # @note `let` can be configured to be threadsafe or not.
  #   If it is threadsafe, it will take longer to access the value.
  #   If it is not threadsafe, it may behave in surprising ways in examples
  #   that spawn separate threads. Specify this on `RSpec.configure`
  # @note Because `let` is designed to create state that is reset between
  #   each example, and `before(:context)` is designed to setup state that

  # Given a `name`, defines a method with that name which returns the

  # implicitly in one-liners and explicitly using an intention revealing
  # name.
