This is just a simple module allowing you to easily test (or just ignore) code that needs to
console.log or otherwise write to standard out and standard error.
npm install --save-dev mock-stdio
var mockIo = ;var expect = expect;;
Note that it is best to use the mock directly inside the test, rather than in
after functions, as it will not be possible for anything within the node process to log to
stderr, meaning you may lose messages that are printed by your test framework.
