# 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 or the new _(value) wrapper. 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
        _(1 + 1).must_equal 2      # good
        value(1 + 1).must_equal 2  # good, also #expect
      end
    end
