This is my current view as well, I just add tests to it. Junior: doesn't know how to create tests for their code Mid: Creates the tests but leaves some important parts untested or tests have bad practices. Experienced: Creates the right tests but might overdo. Senior: Tests only the stuff that matters and knows when it's not worth it.
