Feature: Edit a project

describe('when updating an existing resource /project/:id', function(){
  var project = {
    name: "new test name"
    , user: login.user  
    , token: login.token
    , repositories    : [ "12345", "9898" ]
  };

  it('should respond with 204', function(done){

    request(app)
    .put('/project/' + id)
    .send(project)
    .expect(204, done);
  });
});

Project.prototype.put = function...
