I don't do testing on personal projects, which are probably the fastest-pace projects I work on. At work, I don't do frontend testing since frontend failures aren't serious and the testing I've seen is completely un-ergonomic and valueless. Mind that I consider myself to be full-stack, but with a tilt towards the backend. At work, I do unit testing on the backend of basically every component. Unit testing leads to digestible and sensible code and tests. I've worked with some integration testing, but it doesn't seem worth the cost. I could be convinced otherwise if I worked with a "cleaner" integration test suite. The ones I've touched have been messy hacks.
