I feel your frustration. For the first half my career I didn't do unit testing and NO place I worked ever asked for it. I started to push for it in my current job several years ago and had a challenge getting management to understand that even though our work estimates were larger initially we would ultimately deliver a better product faster because there would be so many fewer bugs. Every professional programmer should be writing unit tests (and preferably practicing TDD) IMHO.

Thanks,
