This may sound weird, but I've written code professionally for 25+ years and I have never written a unit test, I'm not even sure what a "unit test" is or would look like in the context of what I write.
My job is to first consider a dozen ways a new feature might be used; then consider how it could be misused; then write a backend portion and UI for it, testing it for usability and potential for error along the way, using everything I've already thought could go wrong; then monitor it once it's deployed to see if anything actually does go wrong. After actually testing it through everything I can think of by hand, function by function, line by line as I write it, it seems totally stupid to write code to test my own code.
Not to sound like a shit, but that's what end users are for ;)
