Current Project:

I decided that I wanted my tests to automatically run every time I changed a test file. I could do this using the watch flag inside my package.json file:

"scripts": {
  "test": "NODE_ENV=test mocha --compilers js:babel-core/register -w"

However, each time I changed a file, I was receiving the following error:

1)  Uncaught error outside test suite:
    Uncaught Error: listen EADDRINUSE :::8080

A little bit of reading later led me to understand that I was starting my app twice, once from under the tests and another in my actual app.

To fix this error, I simply needed to do the following in my server.js file:

if(!module.parent) {

So now I can write my tests and have them update as I make changes. Saves me having to npm test each time I add/update tests.
