What I also love is the built-in „compilation mode“. I‘ve bound „C-c l“ to „compile“ and „C-c r“ to „recompile“. We have different tests in different directories so I‘ve sprinkled a couple of “.dir-locals.el” in all the relevant places populating all the right default “compilation commands” for me. So when I want to run or create a new test I hit “C-c l” once, select the right default and then recompile after every iteration using “C-c r”. This boosts my turn over so much as any errors are also captured in separate buffer. The tests may even run remotely transparently by leveraging “ssh”.

So you don’t even need a complex configuration for easing many of your daily routines.
