– http://nightwatchjs.org/ „Nightwatch.js is an easy to use Node.js based
End- to-End (E2E) testing solution for browser based apps and websites. It uses the powerful Selenium WebDriver API to perform commands and assertions on DOM elements.“
Nightwatch & WebDriver
Features • Clean syntax • Build-in test runner • support
for CSS and Xpath Selectors • Grouping and filtering of Tests • Saucelab and Browserstack support • Extendable (Custom Commands) • CI support!
Installation $ npm install [-g] nightwatch … and Download Selenium-Server-Standalone!
Done.

Tests in detail
Arrange and assert module.exports = { 'Google Webtechcon' : function
(client) { client .url('http://www.google.com') .waitForElementVisible('body', 1000) .assert.title('Google') .assert.visible('input[type=text]') .end(); } }; arrange assert
Arrange, action and assert module.exports = { 'Google Webtechcon' :
function (client) { client .url('http://www.google.com') .waitForElementVisible('body', 1000) .assert.title('Google') .assert.visible('input[type=text]') .setValue('input[type=text]', 'webtechcon') .waitForElementVisible('button[name=btnG]', 1000) .click('button[name=btnG]') .pause(1000) .assert.containsText('#rso > div.g > div > div > h3 > a', 'WebTech Conference 2016') .end(); } arrange assert assert action
Hardcoded values?
Hardcoded values module.exports = { 'Google Webtechcon' : function (client)
{ client .url('http://www.google.com') .waitForElementVisible('body', 1000) .assert.title('Google') .assert.visible('input[type=text]') .end(); } };
Using globals module.exports = { 'Google Webtechcon' : function (client)
{ var globals = client.globals; client .url(globals.url) .waitForElementVisible('body', 1000) .assert.title(globals.static.pageTitle) .assert.visible(globals.selectors.searchField) .end(); } };
Define globals module.exports = { url: 'http://www.google.com', selectors: { 'searchField':
'input[type=text]' }, static: { 'pageTitle': 'Google' } } Save as data/google.js
Add to config (test-settings) module.exports = { . . .
"test_settings": { "default": { "launch_url": "http://localhost", "selenium_port": 4444, "selenium_host": "localhost", "silent": true, "screenshots": { "enabled": false, "path": "" }, "desiredCapabilities": { "browserName": "chrome", "marionette": true }, "globals": require('./data/google') }, . . .
None
Use Page Objects!
Using Page Objects module.exports = { 'url': 'http://www.google.com', 'elements': {
'searchField': 'input[type=text]' } }; Save as object/google.js
Add objects to config module.exports = { "src_folders": ["tests"], "output_folder":
"reports", "custom_commands_path": "", "custom_assertions_path": "", "page_objects_path": "./objects/", "globals_path": "", "selenium": {. . .}, "test_settings": {. . .} };
Add objects to config module.exports = { 'Google Webtechcon' :
function (client) { var googlePage = client.page.google(), globals = client.globals; googlePage.navigate() .waitForElementVisible('body', 1000) .assert.title(globals.static.pageTitle) .assert.visible('@searchField') .end(); } };
More PageObjects awesomeness module.exports = { 'url': 'http://www.some.url', 'elements': {
'passwordField': 'input[type=text]', 'usernameField': 'input[type=password]', 'submit': 'input[type=submit]' }, commands: [{ signInAsAdmin: function() { return this.setValue('@usernameField', 'admin') .setValue('@passwordField', 'password') .click('@submit'); } }] };
In your test module.exports = { 'Admin log in' :
function (browser) { var login = browser.page.admin.login(); login.navigate() .signInAsAdmin(); browser.end(); } };
Grouping tests $ nightwatch --group smoketests $ nightwatch --skipgroup smoketests
$ nightwatch --skipgroup login,whatever
Test groups | ├──tests/ | ├──smoketests/ | | ├──meaningfulTest1.js |
| ├──meaningfulTest2.js | | └── …… | └──login/ | ├──authAndLogin.js | └── ……
Tag your tests $ nightwatch --tag login $ nightwatch --tag
login --tag something_else $ nightwatch --skiptags login $ nightwatch --skiptags login,something_else
In your test module.exports = { '@tags': ['login', 'sanity'], 'Admin
log in' : function (browser) { var login = browser.page.admin.login(); login.navigate() .signInAsAdmin(); browser.end(); } };
Demo
Nightwatch is extendable! • Write custom commands • add custom
assertions • write custom reporter
Nightwatch is Javascript! • Using Filereaders • CSV, Excel etc.
• write helpers if needed!
