title: test express API requires local server
body: <p>I've read i can run mocha test in an Express application (nodeJS) with super test and therefore it is not required to run the app in a different terminal session.
  Whatever i try it always ends with a connection error.</p>
  
  <p>To configure our continuous integration it is evident the integration and unit test (mocha, supertest, should) should be able to run without the node server is also running</p>
  
  <p>The written tests are to validate our app's internal api end points
  Who can explain how to run the tests without running the express server of the app so they can be integrated with for example strider </p>
