Overview

Common API used for an automated testing in Meteor.

Exports

• Common testing API from @majus/testing Node package tossed through: sinon, chai, etc.

• Refactored StubCollections API: with support for models from jagi:astronomy Meteor package

Installation

meteor add majus:testing

StubCollections API

Inspired by hwillson:stub-collections Meteor package:

Easily stub out Meteor collections with in-memory local collections. The idea here is to allow the use of things like Factories for unit tests and styleguides without having to restrict ourselves to making components "pure". So a component (ie. a template) can still call Widgets.findOne(widgetId), it's just that we will have stubbed out Widgets to point to a local collection that we can completely control in our test.

• StubCollections.stub(collection1, collection2, ...) – stub a specific list of collections
• StubCollections.restore() – undo stubbing (call at the end of tests, on routing away, etc.)

Usage examples

import { expect, sinon, StubCollections } from 'meteor/majus:testing';
import { MyModel, MyCollection, myFunction } from './source';

describe('My tests', () => {

  beforeEach(() => {
    StubCollections.stub(MyCollection, MyModel.getCollection());
  });

  afterEach(() => {
    StubCollections.restore();
    sinon.restore();
  });

  test('myFunction returns current user id', () => {
    const itemId = MyCollection.insert({});
    sinon.stub(Meteor, 'userId').returns('xxx');
    const result = myFunction(itemId);
    expect(result).to.be.equal('xxx');
  });
  
});
