# This cop checks whether `expect_offense` and correction expectation methods
# (i.e. `expect_correction` and `expect_no_corrections`) are separated by empty line.
#
# @example
# # bad
# it 'registers and corrects an offense' do
# expect_offense(<<~RUBY)
# bad_method
# ^^^^^^^^^^ Use `good_method`.
# RUBY
# expect_correction(<<~RUBY)
# good_method
# RUBY
# end
#
# # good
# it 'registers and corrects an offense' do
# expect_offense(<<~RUBY)
# bad_method
# ^^^^^^^^^^ Use `good_method`.
# RUBY
#
# expect_correction(<<~RUBY)
# good_method
# RUBY
