how to use sinon inside server.promise?

[khaledkbadr]

Hello,
I'm trying to stub Meteor.user in server.promise to return random user using sinon. The problem is sinon becomes undefined when I use it inside server.promise even when I add it as parameter. Is there anyway to use it inside server.promise

const sinon = require('sinon');
return server.promise(function (resolve, reject, sinon) {
        sinon.stub(Meteor, 'user').returns({username: 'testuser'});
        Meteor.call('Report.add', data, function(err, result) {
          if(err) {
            reject(err);
          } else {
            resolve(result);
          }
        },[sinon]);
      }).then(function (err) {
        expect(err).to.be.an('null');
      });

It gives me this error Error: Cannot call method 'stub' of undefined
Thanks

@khaledkbadr The only way to achieve that is to make sinon available globally to your entire meteor application. You can use a wrapping debugOnly package to make sure you don't mess up with your production build. Also, when Meteor 1.3 is out you should be able to use "modules" instead of creating a wrapping package. Please note that gagarin is not yet compatible with Meteor 1.3.

Another thing is that Gagarin in it's essence is an integration testing framework. This means in particular that is not really designed to do unit testing, so in particular stubbing is not something that you will have right out of the box. The problem you observed above comes from the fact that arguments to server.promise must be send over DDP to your meteor application working in the background, so you can only use something that is serializable.
