      # This cop enforces custom RSpec dialects.
      #
      # A dialect can be based on the following RSpec methods:
      #
      # - describe, context, feature, example_group
      # - xdescribe, xcontext, xfeature
      # - fdescribe, fcontext, ffeature
      # - shared_examples, shared_examples_for, shared_context
      # - it, specify, example, scenario, its
      # - fit, fspecify, fexample, fscenario, focus
      # - xit, xspecify, xexample, xscenario, skip
      # - pending
      # - prepend_before, before, append_before,
      # - around
      # - prepend_after, after, append_after
      # - let, let!
      # - subject, subject!
      # - expect, is_expected, expect_any_instance_of
      #
      # By default all of the RSpec methods and aliases are allowed. By setting
      # a config like:
      #
      #   RSpec/Dialect:
      #     PreferredMethods:
      #       context: describe
      #
      # You can expect the following behavior:
      #
      # @example
      #   # bad
      #   context 'display name presence' do
      #     # ...
      #   end
      #
      #   # good
      #   describe 'display name presence' do
      #     # ...
      #   end
