Hi

are there any examples of unit testing createContainer code for react?

are you asking about UI testing the component which gets the meteor stream as a prop? or do you mean testing a container to see if the published stream is being received?

I was referring to testing the component - for example -

github.com

meteor/todos/blob/react/imports/ui/containers/ListPageContainer.jsx

import { Meteor } from 'meteor/meteor';
import { withTracker } from 'meteor/react-meteor-data';
import { Lists } from '../../api/lists/lists.js';
import ListPage from '../pages/ListPage.jsx';

const ListPageContainer = withTracker(({ params: { id } }) => {
  const todosHandle = Meteor.subscribe('todos.inList', { listId: id });
  const loading = !todosHandle.ready();
  const list = Lists.findOne(id);
  const listExists = !loading && !!list;
  return {
    loading,
    list,
    listExists,
    todos: listExists ? list.todos().fetch() : [],
  };
})(ListPage);

export default ListPageContainer;

In this case this is a simple container. Our containers are bit more complex and was wondering how to unit test them.

I am also wondering the same thing. How do you test your containers? I am using jest, enzyme, and chai for the simpler things. But I would also like to test the things in withTracker and the state I created in my Container class. Have you figured anything out?
