No, he's not angry. They expect to be 'tested'
Its different for every client. For example, let's say your therapist has figured out that you have issues with authority figures because as a child you were emotionally battered by controlling authority figures. So say that after things just humming along in therapy, you suddenly start showing up late to your appointments. He might wonder if you are subconsciously 'testing' him to see if he will react with the same emotional battery that you were taught to expect. Early in the relationship, therapists expect a lot of testing. If they 'pass,' it goes a long way toward forging a strong therapeutic bond of trust, and they know that.

So it's not a negative thing. And most of the time, the client is doing it subconsciously. They know that too. .
