A bit of a hack to get multiple reporters working with mocha

npm install mocha-multi --save-dev
mocha --reporter mocha-multi

Set an environment variable called multi to specify the desired reporters. Reporters are listed as whitespace separated type=destination pairs.

multi='dot=- xunit=file.xml doc=docs.html' mocha -R mocha-multi

The special value of - (hyphen) for destination uses normal stdout/stderr.

A big hack that keeps changing the value of process.stdout and process.stderr whenever a reporter is doing its thing.

Yeah, Sorry!

This is very hacky, specifically:

• The process and console objects get their internal state messed with
• process.exit is hacked to wait for streams to finish writing
• Only works if reporters queue writes synchronously in event handlers

• Now that mochajs/mocha#1059 is released the process.exit hack could be tidier

• If mochajs/mocha#1061 is accepted upstream, I only need to hijack stdout, and can leave stderr alone

• Having each reporter run in a child process would make it eaiser to capture their streams, but might lead to other issues

• Update hack now that mochajs/mocha#1059 is merged
• Add tests for coverage reports
• Add tests which produce multiple reports at once
• Add test for help text
• Add test that uses --no-exit
• Add test that doesn't use _mocha (maybe not?)
