How to initialize server for testing

On test/users-api.js start the server by including the following:

var debug = require('debug')('Node-API-Testing');
var app = require('../app');

app.set('port', PORT);
app.set('testing', true);

var server = app.listen(app.get('port'), function() {
  debug('Express server listening on port ' + server.address().port);
});

Shippable integration - CI

• Link your account with shippable by following Step 3: Enable CI/CD for repos.

• After the account is linked, when you push changes to the repo shippable will run your tests and code coverage.

• You can see the results under Tests.

• Note that code coverage will not work for this case. This happens because the app is being tested from the outside using superagent. istanbul sees the app as a black box.
