Just to add another perspective. There is a (pretty sad but real) business case for unit tests (don't need be good just need to exist :( ). In some b2b/enterprise fields it is an excellent sales pitch to be able to say we have X% test-coverage or 500 unit tests OMG. The people that make the buy decisions want to sleep well no matter if it is based on sound reasoning or not. Test coverage is almost a "feature" (in the bad enterprise IT sense). Sounds less risky to buy the product with more test coverage. Less risk I can understand it's like buying insurance...which is great since insurance turns risk into a budgetable item...yes please sell me this awesome software with that high test coverage. /cynic
