I am a QA of 10 developers and we have a new developer who has been troubling me for 5 months.
Every bug I assign to him I always get complaints from him. Then when he sees one bug he would tell fellow developer that I never tested the app. There is one issue that was raised a few months ago and was logged as a bug but it remained open for further investigation. The environment was changed and it resolved the issue - but the issue is still open for the same reason. He again said this was never tested.
This bothers me so much as I had been very diligent with my tests and this guy has always been spoonfed and shows no accountability or no interest in resolving a bug. He dodges the issue and blames it on the QA.
How can I approach this situation in a professional way?
I have already talked with my boss about this but since he is under probationary and well, legal terms, he tries to give this person a chance. He gets the chance but he still tears the QA down.
