Is she testing me with the silent treatment?

I've been taking to a mutual friend for about a month. Things were going well until I forgot to invite her out last Friday with some people. I could tell by her reaction the next morning she wasn't happy about it. I tried inviting her out on Saturday but she never responded and I haven't heard from her since. Is this just a test to see if I'm gonna apologize or try begging? Typically, if a girl doesn't respond to a text, then I will not text them back (which I haven't). But I am just curious. She's actually been known to start up drama and is pretty high maintenance of that matters. We both like each other, but I'm not into any games...
