Thank's in advance!
@masylum it's a little gross, but here's how I've integrated bunker / coverage into my testing library, platoon: https://github.com/chrisdickinson/platoon/blob/master/lib/cover.js#L43.
I had to add a "buildContext" to bunker to separate the context building from actually running the code -- bunker uses vm.runInNewContext which screws up instanceof checks.
interesting! I'm checking now the brand new node-intestine :) https://github.com/substack/node-intestine
