Bite inhibition is essential. Of course, you also want her to learn that biting you, especially under these circumstances, is unacceptable. When she does this, you can yelp like a dog would, fold your hands across your chest to take them away from her, and get up and leave. Ignore her. She should get the message quickly that biting you or growling at you will result in you leaving and not paying attention to her. If she tries to physically engage when you walk away, then leave the room and go where she can't follow (make sure she is safe wherever you leave her unattended).
At that age, they test their boundaries.
