Protractor

Protractor helper is based on Protractor library and used for testing AngularJS applications.

Selenium Installation

  1. Download Selenium Server
  2. For Chrome browser install ChromeDriver, for Firefox browser install GeckoDriver.
  3. Launch the server: java -jar selenium-server-standalone-3.xx.xxx.jar. To locate Chromedriver binary use -Dwebdriver.chrome.driver=./chromedriver option. For Geckodriver use -Dwebdriver.gecko.driver=.

PhantomJS Installation

PhantomJS is a headless alternative to Selenium Server that implements the WebDriver protocol. It allows you to run Selenium tests on a server without a GUI installed.

  1. Download PhantomJS
  2. Run PhantomJS in WebDriver mode: phantomjs --webdriver=4444

Configuration

This helper should be configured in codecept.json

  • url - base url of website to be tested
  • browser - browser in which perform testing
  • driver - which protrator driver to use (local, direct, session, hosted, sauce, browserstack). By default set to 'hosted' which requires selenium server to be started.
  • restart (optional, default: true) - restart browser between tests.
  • smartWait: (optional) enables SmartWait; wait for additional milliseconds for element to appear. Enable for 5 secs: "smartWait": 5000
  • seleniumAddress - Selenium address to connect (default: http://localhost:4444/wd/hub)
  • rootElement - Root element of AngularJS application (default: body)
  • waitForTimeout: (optional) sets default wait time in ms for all wait* functions. 1000 by default.
  • scriptsTimeout: (optional) timeout in milliseconds for each script run on the browser, 10000 by default.
  • windowSize: (optional) default window size. Set to maximize or a dimension in the format 640x480.
  • manualStart (optional, default: false) - do not start browser before a test, start it manually inside a helper with this.helpers["WebDriverIO"]._startBrowser()
  • capabilities: {} - list of Desired Capabilities
  • proxy: set proxy settings

other options are the same as in Protractor config.

Example:

{
   "helpers": {
     "Protractor" : {
       "url": "http://localhost",
       "browser": "chrome",
       "smartWait": 5000,
       "restart": false
     }
   }
