Overview

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
