Both test_move and test_orphan needed internal knowledge which comes with the addition of the "in" attribute. This was in the plan for the test-revamp from the beginning as it really opens up the ability to write more unit-style-tests using internal knowledge of how littlefs works. More unit-style-tests should help _fix_ bugs by limiting the scope of the test and where the bug could be hiding. The "in" attribute effectively runs tests _inside_ the .c file specified, giving the test access to all static members without needed to change their visibility.
