Shes either liking what your doing and wanna see if you are congruent or just tricking her,want to see what she can get away with or just blanty disrespecting you....if she continues to do you either not passing her tests or shes just poking more to dig something to see how would you react not to her but with people in general  etc... Either way everyone will be tested but if she sees you as "the man" she will be scared to test you because she dont wanna lose you... With family etc. When they see weakness they will go on attack to provoke you with tests its a way to get you out of that weakness but it mostly never works...
