How do I test a publication that uses `this.userId` ?

[NaderIkladious]

Hello,

I have this problem that I want to test a publication that only return content for current logged in user (this.userId)

how do i test it without mocking it? is there a way to set this.userId for publication in test ?

Thanks in advance,
Nader Ikladious.

@NaderIkladious It depends on what method you're using. Can you please send me the corresponding test snippet?

Here is the publication I want to test

Meteor.publish('posts', function() {
  return Posts.find({userId: this.userId});
});

And here is the test code

it('Should return all post for current user"', function () {
    return client.promise(function(resolve, reject) {
      Meteor.subscribe('posts', 'jmQdsySz88dEzQDSA', function() {
        resolve(Posts.find().fetch().length)
      });
  }).then(function (result) {
    expect(result).to.be.equal(50);
  });

This test won't work as the publication only publish posts for current user and it would be null while executing it in test.

Thanks.

@NaderIkladious Sorry for not responding sooner.

I think that what may help you in this particular use-case is the login helper:

https://github.com/anticoders/gagarin/blob/master/lib/browser/helpers.js#L156-L160

so you would need to do something like this:

before(function () {
  return client.login('username', 'password');
});

Also, if you're only planning to test subscriptions and methods, then there's actually no need to spin up a browser instance. You can use a "raw" ddp client instead, look here to find some examples:

I hope it helps a little.
