# Checks if `.to`, `not_to` or `to_not` are used.
#
# The RSpec::Expectations::ExpectationTarget must use `to`, `not_to` or
# `to_not` to run. Therefore, this cop checks if other methods are used.
#
# @example
# # bad
# expect(something).kind_of? Foo
# is_expected == 42
# expect{something}.eq? BarError
#
# # good
# expect(something).to be_a Foo
# is_expected.to eq 42
# expect{something}.to raise_error BarError
