WebDriverIO
WebDriverIO
WebDriverIO helper which wraps webdriverio library to manipulate browser using Selenium WebDriver or PhantomJS.
Selenium Installation
- Download Selenium Server
- For Chrome browser install ChromeDriver, for Firefox browser install GeckoDriver.
- 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.
- Download PhantomJS
- 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 -
restart
(optional, default: true) - restart browser between tests. -
keepCookies
(optional, default: false) - keep cookies between tests whenrestart
set to false. -
windowSize
: (optional) default window size. Set tomaximize
or a dimension in the format640x480
. -
waitForTimeout
: (option) sets default wait time in ms for allwait*
functions. 1000 by default; -
desiredCapabilities
: Selenium's desired capabilities -
manualStart
(optional, default: false) - do not start browser before a test, start it manually inside a helper withthis.helpers["WebDriverIO"]._startBrowser()
-
timeouts
: WebDriverIO timeouts defined as hash.
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" } } } } } }
