I have to make a big decision about my future as a developer...
(Long rant)

I am currently in an apprenticeship as a dev.
The thing is i was forced to do testautomatization.

I was there for half a year and had a good time.
But now my trainer (the guy who assigned me all the work and showed me all the stuff I learned) has been fired.

And now it sucks... they don't teach me new things anymore and don't give me time to catch up with the new technologies.
(This was different in the past!)

I was forced to do manual testing for the past few week.
Therefor i am working with a friend and his trainer.

One day i was talking to my friend about how things have changed in the testing-team.

His trainer was listening (we did not know) and sayed: If you want i can ask my boss if it is possible that i can teach you as well.

Now the point is i woud love to work with him. I love the work they do!! (Java; don't hate me)

But it will make the testing guys mad and I dont know how HR will react.

I am pretty sure it will reduce my chances of getting a job (at this company) if I change the team...

Should I talk to HR or not? What do you think?

Thanks for reading and sorry for my english bugs.
