I don't understand how there is actually tests here? There just seems to be configurations, but nothing saying that configuration 1 should be parsed as X.

Are you referring to the unit tests that I wrote? I parse an ios configuration and use the functions that are written: find_all_children and find_children_w_parents. These two functions are the units under test. Then I compare the output of these functions with the expected output. If the test passes, I consider the unit, i.e. the functions mentioned, tested. I also consider that this is the expected behavior. Are you expecting something different for the unit tests?
