protractor-ci

Protractor CI

Warning

This project is alpha status. Use at your own risk.

Goals

• Run E2E tests against all target browsers.
• Run E2E tests on Travis CI.
• Mock requests to external APIs (semi-automatically).

Installation

npm install protractor-ci --save-dev

Workflow

1. Run E2E tests against locally against live dev API This step records all external API requests for later playback.

2. Verify test playback Uses the recorded mock requests from step 1.

3. Run E2E tests against Sauce Labs Uses the recorded mock requests from step 1.

4. Run E2E tests on Travis CI on deployment Uses the recorded mock requests from step 1.

Run Local E2E Tests

Define the task:

var pXor = require('protractor-ci');

gulp.task('test:e2e:record', function(cb) {
  var opts = {
    nodeApp:   'test/app.js',
    nodeHost:  'localhost',
    nodePort:  7777,
    record:    true,
    mockFile:  'mocks/nock-mocks.json',
    specs: [
      'test/e2e/*.coffee'
    ]
  };

  pXor.e2e.testE2E(opts).then(function() { cb(); });
});

Run the task:

gulp test:e2e:record

Playback E2E Tests

Define the task:

var pXor = require('protractor-ci');

gulp.task('test:e2e:playback', function(cb) {
  var opts = {
    nodeApp:   'test/app.js',
    nodeHost:  'localhost',
    nodePort:  7777,
    playback:  true,
    mockFile:  'mocks/nock-mocks.json',
    specs: [
      'test/e2e/*.coffee'
    ]
  };

  pXor.e2e.testE2E(opts).then(function() { cb(); });
});

Run the task:

gulp test:e2e:playback

Playback E2E Tests using SauceLabs

var pXor = require('protractor-ci');

// define task to start sauce connect
gulp.task('start-sauce-connect', function(cb) {
  pXor.e2e.startSauceConnect().then(function() { cb(); });
});

// define test runner
gulp.task('test:e2e:ci', function(cb) {
  var opts = {
    nodeApp:   'test/app.js',
    nodeHost:  'localhost',
    nodePort:  7777,
    playback:  true,
    mockFile:  'mocks/nock-mocks.json',
    specs: [
      'test/e2e/*.coffee'
    ],
    browsers: [{
      browserName:         'chrome',
      build:               process.env.TRAVIS_BUILD_NUMBER,
      'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER
    }, {
      browserName:         'firefox',
      build:               process.env.TRAVIS_BUILD_NUMBER,
      'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER
    }, {
      browserName:         'safari',
      build:               process.env.TRAVIS_BUILD_NUMBER,
      'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER
    }, {
      browserName:         'internet explorer',
      version:             11,
      build:               process.env.TRAVIS_BUILD_NUMBER,
      'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER
    }, {
      browserName:         'internet explorer',
      version:             10,
      build:               process.env.TRAVIS_BUILD_NUMBER,
      'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER
    }, {
      browserName:         'internet explorer',
      version:             9,
      build:               process.env.TRAVIS_BUILD_NUMBER,
      'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER
    }, {
      browserName:         'internet explorer',
      version:             8,
      build:               process.env.TRAVIS_BUILD_NUMBER,
      'tunnel-identifier': process.env.TRAVIS_JOB_NUMBER
    }]
  };

  pXor.e2e.testE2E(opts).then(function() { cb() });
});

Now open two terminal windows.

In the first terminal:

gulp start-sauce-connect

Leave the terminal open. The task will let you know when it's ready to start the tests.

In the second terminal:

gulp test:e2e:ci

Travis CI Setup

First follow these instructions.

Next, make sure the before_install and addons blocks exist in your .travis.yml file:

language: node_js
node_js:
- 'x.xx'

env:
  global:
  - secure: xxx
  - secure: yyy
  - NODE_ENV=travis

addons:
  sauce_connect: true

cache:
  directories:
    - node_modules

before_install:
- npm install
- node_modules/.bin/bower install --config.directory=path/to/test/server

The goal is to ensure that the dev server has everything it needs to be run by Travis. More steps may be required depending on your application.

Then, in your package.json file:

{
  // ...
  "scripts": {
    "test": "gulp test:e2e:ci"
  },
  // ...
}
