Learning stuff about nodejs (or v8) while writing tests that ensure runtime behaviour, using process.cpuUsage and process.memoryUsage. Curious how brittle those tests become over time. Glad the app ALWAYS runs in the same docker container (dev and prod).

Why a #mocha #test times out, when I write it like this: it('...', _ => {}); but it does NOT time out, when I write: it('...', () => {});? Exactly, because the _ is the magic done, that one needs to call.
