cypress-angularjs-unit-test BETA

Unit test Angularjs code using Cypress.io test runner

NPM

Build status semantic-release standard renovate-app badge

Motivation

You can use Cypress.io to end-to-end test any application, but what if you want to test your Angular.js values, services, controllers and components individually? This adaptor allows you to do this very quickly. See each test run as a mini app inside a real browser, go back in time using DOM snapshot, etc - all the good things available in E2E tests are working in unit tests.

Install

Requires Node version 6 or above.

npm install --save cypress-angularjs-unit-test cypress

Requires angular peer dependency

Use

import {mount} from 'cypress-angularjs-unit-test'
// or const mount = require('cypress-angularjs-unit-test').mount
import angular from 'angular'
// prepare app
it('works', () => {
  const template = '... HTML template ... '
  const modules = ['module1', 'module2', '...']
  mount(template, modules)
})

Basic example

See cypress/integration/basic-spec.js

import {mount} from 'cypress-angularjs-unit-test'
import angular from 'angular'

angular.module('demo', [])
  .controller('WelcomeController', function($scope) {
    $scope.greeting = 'Welcome!';
    $scope.version = angular.version.full
  });

beforeEach(() => {
  // let's mount our "demo" module and its controller
  // in a "mini app" before each test
  const template = `
    <div ng-controller="WelcomeController">
      {{greeting}}
      ng {{version}}
    </div>
  `
  mount(template, ['demo'])
})

it('shows hello', () => {
  // "WelcomeController" should have replaced template
  // expression {{greeting}} with actual text
  cy.contains('div', 'Welcome!').should('be.visible')
})

Examples

Notes

  • npm run cy opens Cypress end-to-end test runner in GUI mode
  • npm test runs Cypress in headless mode
  • mount uses angular.bootstrap to mount code inside the test iframe.

Cypress can do everything you can do from DevTools console when dealing with Angular.js application.
