WebDriverIO

WebDriverIO helper which wraps webdriverio library to manipulate browser using Selenium WebDriver or PhantomJS.

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

Example:

{
   "helpers": {
     "WebDriverIO" : {
       "browser": "chrome",
       "restart": false,
       "windowSize": "maximize",
       "timeouts": {
         "script": 60000,
         "page load": 10000,
         "implicit" : 5000
       }
     }
   }
}

Additional configuration params can be used from webdriverio website.

Connect through proxy

CodeceptJS also provides flexible options when you want to execute tests to Selenium servers through proxy. You will need to update the helpers.WebDriverIO.desiredCapabilities.proxy key.

{
    "helpers": {
        "WebDriverIO": {
            "desiredCapabilities": {
                "proxy": {
                    "proxyType": "manual|pac",
                    "proxyAutoconfigUrl": "URL TO PAC FILE",
                    "httpProxy": "PROXY SERVER",
                    "sslProxy": "PROXY SERVER",
                    "ftpProxy": "PROXY SERVER",
                    "socksProxy": "PROXY SERVER",
                    "socksUsername": "USERNAME",
                    "socksPassword": "PASSWORD",
                    "noProxy": "BYPASS ADDRESSES"
                }
            }
        }
    }
}

For example,

{
    "helpers": {
        "WebDriverIO": {
            "desiredCapabilities": {
                "proxy": {
                    "proxyType": "manual",
                    "httpProxy": "http://corporate.proxy:8080",
                    "socksUsername": "codeceptjs",
                    "socksPassword": "secret",
                    "noProxy": "127.0.0.1,localhost"
                }
            }
        }
    }
}

Please refer to Selenium - Proxy Object for more information.

Cloud Providers

WebDriverIO makes it possible to execute tests against services like Sauce Labs BrowserStack TestingBot Check out their documentation on available parameters

Connecting to BrowserStack and Sauce Labs is simple. All you need to do is set the user and key parameters. WebDriverIO automatically know which service provider to connect to.

{
    "helpers":{
        "WebDriverIO": {
            "url": "YOUR_DESIERED_HOST",
            "user": "YOUR_BROWSERSTACK_USER",
            "key": "YOUR_BROWSERSTACK_KEY",
            "desiredCapabilities": {
                "browserName": "chrome",

                // only set this if you're using BrowserStackLocal to test a local domain
                // "browserstack.local": true,

                // set this option to tell browserstack to provide addition debugging info
                // "browserstack.debug": true,
            }
        }
    }
}

Multiremote Capabilities

This is a work in progress but you can control two browsers at a time right out of the box. Individual control is something that is planned for a later version.

Here is the webdriverio docs on the subject

{
    "helpers": {
        "WebDriverIO": {
            "multiremote": {
                "MyChrome": {
                    "desiredCapabilities": {
                        "browserName": "chrome"
                     }
                },
                "MyFirefox": {
                   "desiredCapabilities": {
                       "browserName": "firefox"
                   }
                }
            }
        }
    }
}
