Overview

Note:

Example blocks are evaluated in the context of an instance of an ‘ExampleGroup`, not in the context of an instance of `Example`.

Wrapper for an instance of a subclass of ExampleGroup. An instance of ‘RSpec::Core::Example` is returned by example definition methods such as it and is yielded to the it, before, after, around, let and subject blocks.

This allows us to provide rich metadata about each individual example without adding tons of methods directly to the ExampleGroup that users may inadvertently redefine.

Useful for configuring logging and/or taking some action based on the state of an example’s metadata.

Examples:


RSpec.configure do |config|
  config.before do |example|
    log example.description
  end

  config.after do |example|
    log example.description
  end

  config.around do |example|
    log example.description
    example.run
  end
end

shared_examples "auditable" do
  it "does something" do
    log "#{example.full_description}: #{auditable.inspect}"
    auditable.should do_something
  end
end

Constructor Details

#initialize(example_group_class, description, user_metadata, example_block = nil) ⇒ Example

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Creates a new instance of Example.

Parameters:

  • example_group_class (Class) —

    the subclass of ExampleGroup in which this Example is declared

  • description (String) —

    the String passed to the ‘it` method (or alias)

  • user_metadata (Hash) —

    additional args passed to ‘it` to be used as metadata

  • example_block (Proc) (defaults to: nil) —

    the block of code that represents the example

  # Register the example with the group before creating the metadata hash.
  # This is necessary since creating the metadata hash triggers
  # `when_first_matching_example_defined` callbacks, in which users can
  # load RSpec support code which defines hooks. For that to work, the
  # examples and example groups must be registered at the time the
  # support code is called or be defined afterwards.
  # Begin defined beforehand but registered afterwards causes hooks to
  # not be applied where they should.
