Webdrivers

Gem Version Build status AppVeyor status

Run Selenium tests more easily with automatic installation and updates for all supported webdrivers.

Description

webdrivers downloads drivers and directs Selenium to use them. Currently supports:

Usage

In your Gemfile:

gem 'webdrivers', '~> 3.0'

In your project:

require 'webdrivers'

The drivers will now be automatically downloaded or updated when you launch a browser through Selenium.

Specific Drivers

If you want webdrivers to only manage specific drivers you can specify as follows:

require 'webdrivers/chromedriver'
require 'webdrivers/iedriver'

Download Location

The default download location is ~/.webdrivers directory, and this is configurable:

 Webdrivers.install_dir = '/webdrivers/install/dir'

Version Pinning

If you would like to use a specific (older or beta) version, you can specify it for each driver. Otherwise, the latest (stable) driver will be downloaded and passed to Selenium.

# Chrome
Webdrivers::Chromedriver.required_version = '2.46'

# Firefox
Webdrivers::Geckodriver.required_version  = '0.23.0'

# Microsoft Internet Explorer
Webdrivers::IEdriver.required_version     = '3.14.0'

# Microsoft Edge
Webdrivers::MSWebdriver.required_version  = '17134'

You can explicitly trigger the update in your code, but this will happen automatically when the driver is initialized:

Webdrivers::Chromedriver.update

Caching Drivers

You can set Webdrivers to only look for updates if the previous check was longer ago than a specified number of seconds.

Webdrivers.cache_time = 86_400

The default in 3.9 is zero, and the default for 4.x will be 24 hours (86,400 seconds)

Proxy

If there is a proxy between you and the Internet then you will need to configure the gem to use the proxy. You can do this by calling the configure method.

Webdrivers.configure do |config|
  config.proxy_addr = 'myproxy_address.com'
  config.proxy_port = '8080'
  config.proxy_user = 'username'
  config.proxy_pass = 'password'
end

SSL_connect errors

If you are getting an error like this (especially common on Windows):

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

Add the following to your Gemfile:

gem "net_http_ssl_fix"

Add the following to your code:

require 'net_http_ssl_fix'

Other solutions are documented on the RubyGems website.

Logging

The logging level can be configured for debugging purpose:

Webdrivers.logger.level = :DEBUG

Browser Specific Notes

Chrome/Chromium

The version of chromedriver will depend on the version of Chrome you are using it with:

  • For versions >= 70, the downloaded version of chromedriver will match the installed version of Google Chrome. More information here.
  • For versions <= 69, chromedriver version 2.46 will be downloaded.
  • For beta versions, you'll have to set the desired beta version of chromedriver using Webdrivers::Chromedriver.required_version.

The gem, by default, looks for the Google Chrome version. You can override this by providing a path to the Chromium binary:

Selenium::WebDriver::Chrome.path = '/chromium/install/path/to/binary'

This is also required if Google Chrome is not installed in its default location.

Microsoft Edge

Microsoft Edge support has been removed for now, as it is currently unreliable.

To use Microsoft Edge, please visit the Downloads and Installation page
