Show HN: Nyc – the coverage tool that works with every Node.js testing framework

My coworker Isaac and I have been hacking on this nifty little tool for a few weeks now.

The main problem that we had to overcome was that test frameworks like node-tap (https://github.com/isaacs/node-tap) spawn many subprocesses.

nyc overrides child_process.spawn, collects coverage reports for all child processes, and pulls a coverage report back together again.
