Hard to say without details, because there are many ways to respond to a **** test and maybe you are over-reacting or responding the wrong way. But assuming you aren't, then it sounds like she is really dominant and is trying to have a power struggle with you or she doubts you so keeps testing. Or she could just be a brat, plain and simple. Assuming you are handling it correctly, then it doesn't paint a good picture of her. I'm learning that with girls like this, you have to adopt an attitude of "get with the program or get lost" and you must truly be willing to walk away and never look back. It's like they crave dominance, yet they want to dominate you. If you let them dominate you, they are happy but have no sexual interest in you so they move on or friend zone you. On the other hand, if you dominate them, they get really frustrated yet turned on. Definitely not relationship material but good practice, and good for a short intense fling.
Next time have more of a dismissive vibe. There's an element of fear in power and charisma. People have to almost be afraid of you to take you seriously. Every girl that has ever been attracted to me was afraid of me on some level.
