Programmatic Mocha script for CodeShip.io - Starts an express app, and runs any .js tests in the tests folder. This allows a node.js Swagger.js rest API to be testable on travis-ci and codeship.io.

/*

  Programmatic Mocha code - This is used by a codeship
  test to both start an expressjs app, setup routes and 
  run a suite of mocha tests.
  
  Hint: Place this in the root of the project. Call from 
  test package.js or setup with > node mocha.js
