Selenium Cookbook

This cookbook installs and configures Selenium and WebDriver components (http://www.seleniumhq.org/).

This cookbook comes with the following Resource/Providers:

• selenium_hub - Installs and configures selenium-grid hubs.
• selenium_node - Installs and configures selenium-grid nodes with support for ChromeDriver, FirefoxDriver, HtmlUnitDriver, and InternetExplorerDriver.
• selenium_phantomjs - Installs and configures PhantomJS as a selenium-grid node or as a standalone server via GhostDriver.

Roadmap

• Add support for Appium

Requirements

• Chef 11.14 or higher (sensitive resource introduced)

Platforms

• CentOS, RedHat
• Mac OS X
• Ubuntu
• Windows

Cookbooks

These cookbooks are referenced with suggests, so be sure to depend on cookbooks that apply:

• windows
• nssm - Required for Windows services only (e.g. Hub, PhantomJS, and HtmlUnit running in background)

Usage

See selenium_test cookbook for working cross platform examples. Note that provided examples in this cookbook have passwords unencrypted for simplicity.

selenium_hub

Installs and configures selenium-grid hubs.

Requirements

• Java must be installed outside of this cookbook.

Example

Install selenium-grid hub

selenium_hub 'selenium_hub' do
  action :install
end

Attributes

This is a partial list of attributes available. See hub resource for the complete listing of attributes.

• name - Name attribute. The name of the service.
• host - Hostname. Defaults to null.
• port - Port. Defaults to 4444.

selenium_node

Installs and configures selenium-grid nodes with support for ChromeDriver, FirefoxDriver, HtmlUnitDriver, and InternetExplorerDriver.

Requirements

• Java must be installed outside of this cookbook.
• Browsers (e.g., chrome, firefox, etc...) must be installed outside of this cookbook.
• Linux nodes without a physical monitor require a headless display (e.g., xvfb, x11vnc, etc...) and must be installed and configured outside this cookbook.
• Mac OS X/Windows nodes (with the exception of HtmlUnitDriver) must run as a GUI service and that requires a username and password for automatic login. Note that Windows password is stored unencrypted under windows registry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and Mac OS X password is stored encrypted under /etc/kcpassword but it can be easily decrypted.

Example

Install selenium-grid node with Chrome, Firefox, HtmlUnit and Internet Explorer capability

selenium_node 'selenium_node' do
  username 'Administrator' if platform?('windows')
  password 'password' if platform?('windows')
  capabilities [
    {
      browserName: 'chrome',
      maxInstances: 5,
      seleniumProtocol: 'WebDriver'
    },
    {
      browserName: 'firefox',
      maxInstances: 5,
      seleniumProtocol: 'WebDriver'
    },
    {
      browserName: 'htmlunit',
      maxInstances: 1,
      platform: 'ANY',
      seleniumProtocol: 'WebDriver'
    },
    {
      browserName: 'internet explorer',
      maxInstances: 1,
      seleniumProtocol: 'WebDriver'
    }
  ]
  action :install
end

Attributes

This is a partial list of attributes available. See node resource for the complete listing of attributes.

• name - Name attribute. The name of the service or Windows foreground startup script.
• host - Hostname. Defaults to null.
• port - Port. Defaults to 5555.
• hubHost - Selenium-grid hub hostname. Defaults to ip.
• hubPort - Selenium-grid hub port. Defaults to 4444.
• capabilities - The following drivers are supported and installed based on capabilities:
  • ChromeDriver - Installed if capabilities contains browser name chrome
  • FirefoxDriver - Pre-installed with Selenium server
  • HtmlUnitDriver - Pre-installed with Selenium server
  • InternetExplorerDriver - 32-bit or 64-bit installed if capabilities contains browser name internet explorer
• Mac OS X/Windows only - Set both username and password to run as a GUI service or leave nil to run service in background:
  • username - Defaults to nil.
  • password - Defaults to nil. Note that Windows password is stored unencrypted under windows registry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and Mac OS X password is stored encrypted under /etc/kcpassword but it can be easily decrypted.
  • domain - Optional. Defaults to nil.

selenium_phantomjs

Installs and configures PhantomJS as a selenium-grid node or as a standalone server via GhostDriver (Mac OS X is not supported).

Requirements

• PhantomJS must be installed outside of this cookbook.
• Windows nodes have the option to run as a GUI service and that requires a username and password to automatically login. Note that Windows password is stored unencrypted under windows registry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.

Examples

Install PhantomJS as a selenium-grid node

selenium_phantomjs 'selenium_phantomjs' do
  action :install
end

Install PhantomJS as a standalone server by setting webdriverSeleniumGridHub to false

selenium_phantomjs 'selenium_phantomjs_nogrid' do
  webdriverSeleniumGridHub false
  action :install
end

Attributes

This is a partial list of attributes available. See phantomjs resource for the complete listing of attributes.

• name - Name attribute. The name of the service or Windows foreground startup script.
• webdriver - Webdriver ip:port. Defaults to #{node['ipaddress']}:8910.
• webdriverSeleniumGridHub - Webdriver selenium-grid hub url. Set to false to install PhantomJS as a standalone service. Defaults to http://#{node['ipaddress']}:4444.
• Windows only - Set both username and password to run as a GUI service or leave nil to run service in background:

ChefSpec Matchers

The Selenium cookbook includes custom ChefSpec matchers you can use to test your own cookbooks.

Example Matcher Usage

expect(chef_run).to install_selenium_hub('resource_name').with(
  port: '4444'
)

Selenium Cookbook Matchers

• install_selenium_hub(resource_name)
• install_selenium_node(resource_name)
• install_selenium_phantomjs(resource_name)
