Most of the typoos and obvious errors are caught by IDE thanks to intelligent code completion systems and linters. If you're writing in a compiled language - compile step might catch some of the more obvious errors too. I manually test my current branch manually while developing and do sanity checks when it's merged somewhere. I do write tests for some cases, but rarely, only to save time when I have to test against a wide range of input parameters.
