Explanation of this test?

[benkoshy]

Please refer to the test noted here:

pagy/test/pagy/i18n_locales_test.rb

Line 30 in b226ae7

_(rules).must_include rule, message

Here is a reproduction:

  it 'includes a comment with the pluralization rule and the i18n.rb reference' do
      _(rules).must_include rule, message
      # what does the message variable do?
      # I had added the following random letters and the tests pass perfectly?
      _(rules).must_include rule, "asdf asdf " # passes
    end

It seems like it should not pass?

IIRC the message is an optional/custom param that gets printed when the test fails. Changing it doesn't affect the outcome of the test, only its caption/description.

In this case it provides custom feedback pointing to the file that failed.
