module Minitest::Expectations - minitest-5.0.7 Documentation

# module Minitest::Expectations

It’s where you hide your “assertions”.

Please note, because of the way that expectations are implemented, all expectations (eg #must_equal) are dependent upon a thread local variable `:current_spec`. If your specs rely on mixing threads into the specs themselves, you’re better off using assertions. For example:

    it "should still work in threads" do
      my_threaded_thingy do
        (1+1).must_equal 2  # bad
        assert_equal 2, 1+1 # good
      end
    end
