    -> controller

var GambleController = {

  index: function(req, res) {
      res.send('Hello World!');
  }


};
module.exports = GambleController;

However , how can i write a test to test index function that output Hello world? Any one can give a example? Thanks

Answer 1

You could use superagent, there are some example usages, here's one

describe('/signout', function() {
  var agent = superagent.agent();
  it('should start with signin', loginUser(agent));
  it('should sign the user out', function(done) {
    agent.get('http://localhost:3000/signout').end(function(err, res) {
      res.should.have.status(200);
      res.redirects.should.eql(['http://localhost:3000/']);
      res.text.should.include('Who are you?');
      return done();
    });
  });
  // ...

It should be pretty simple to stub out the result object:

describe('when we get the game controller', function () {
   it ('should return hello world', function (done) {
      GameController.index(null, {
         send: function (message) {
            assert.equal(message, 'Hello World!');
            done();
         };
      });
   });
});
