mocha-aura

Test your Salesforce Lightning components with mocha

Why?

Salesforce Aura components controller and helper files does not export anything and can not be directly required by nodejs. mocha-aura modifies standard nodejs loader for Salesforce Aura components and exports containing object.

Code coverage with istanbul

mocha-aura can act as istanbul --post-require-hook and patch istanbul hookRequire hook. This allows to export Salesforce Aura controller and helper files before instrumenting it and have code coverage metrics.

Installation

Clone this repo or download using yarn or npm

npm install mocha-aura --save

Hooks

mocha-aura hooks nodejs require and istanbul hookRequire to properly load Salesforce js assets. By default it uses standard Salesforce naming convention, where all Aura files located in src/aura folder. For different project structure you may supply your custom regex using AURA_HOOK_REGEX environment variable.

Usage

Run test

mocha --require mocha-aura 'specs/**/*.js' Run all specs from specs folder

Run code coverage

istanbul cover -x 'specs/**/*.js' --root '../src/aura' --include-all-sources --post-require-hook mocha-aura ./node_modules/mocha-runner/bin/runner.js -- 'specs/**/*.js' html text-summary

Here is the simple script section of package.json

  "scripts": {
    "test": "mocha  --require mocha-aura 'specs/**/*.js'",
    "watch": "chokidar --initial './specs/**' '../src/aura/**/*.js' -c 'npm run test'",
    "coverage": "istanbul cover -x 'specs/**/*.js' --root '../src/aura' --include-all-sources --post-require-hook mocha-aura ./node_modules/mocha-runner/bin/runner.js -- 'specs/**/*.js' html text-summary"
  },

To start simple test you have to pass --require mocha-aura to mocha. To run istanbul cover command you have to pass --post-require-hook mocha-aura parameter.

Specs for Lightning controller:

const ctl = require('../../../src/aura/EventDuration/EventDurationController');
 
describe('EventDuration', function() {
  describe('EventDurationController', function() {
    it('doInit should call buildTimezoneObj', function() {
      const helper = {
        buildTimezoneObj: sinon.spy()
      }
      const controller = {}
      ctl.doInit(controller, null, helper);
      expect(helper.buildTimezoneObj).to.have.been.calledWith(controller);
    });
  });
});
