My manager in my old company (company A) left halfway through the time I was there and no-one really bothered to check up on my work after that. During the interview I mentioned things I got up to and so on.
Now the issue I have is that after my manager left I started doing some automated testing because I wanted to improve as a developer (the company did manual testing) and my manager never really got to see me do this. After he left, the other more experienced developers never bothered to checked my work. I've given my manager and another developer as references (company A closed down by the way). So basically no-one saw do this part of the job which I mentioned in my interview. I left because I started my Masters and I honestly don't know if anyone bothered to check my code after that.
Should I be worried if they ask my references about this part of my job? I'm not entirely sure what HR asks, but for software developer positions could it be more specific to what I done on the job?
