A few days ago, I spent a couple of hours trying to get a Jest+Enzyme test to open in chrome inspector, (apparently there's a bug which causes debugger statements in Jest tests to be ignored), because I hit an edge case bug in a method in the Enzyme library. If I had been able to step through it in the debugger, it would have taken me minutes to figure it out, instead I spent a couple of hours going through the codebase and figuring out where to put the log statements.
