Travis CI Build Keeps Failing
<p>I have a project that I am trying to incorporate Travis CI into for testing.</p>

<p>For the life of me, Travis CI keeps 'failing' when I do a Pull Request and/or push to my repos on GitHub. </p>

<p>Here is my <code>.travis.yml</code> file:</p>

<pre><code>language: node_js
node_js:
  - "node"
before_script:
  -npm install -g webpack
  -npm install -g mocha
  -npm install -g chai
  -npm start
  - export DISPLAY=:99.0
  - sh -e /etc/init.d/xvfb start
</code></pre>

<p>Here is the message from Travis CI about the error:</p>

<pre><code>Using worker: worker-linux-docker-f87d2e7f.prod.travis-ci.org:travis-linux-7
