Selenium::Webdriver

Selenium Webdriver bindings for the Crystal programming language.

WARNING: this shard initialy implemented the now obsolete JsonWireProtocol, but should be compatible with the W3C Webdriver spec.

Known working combinations are Selenium 2.48.2 and Firefox 34 (JSONWireProtocol), as well as Selenium 3.5.3, Firefox 55 and the now required Geckodriver 0.18.0 (W3C Webdriver).

See https://github.com/matthewmcgarvey/selenium.cr for an up-to-date library (as of June 2020) that implements the W3C Webdriver spec directly.

Usage

Only the Remote driver is available, so you need to download the release Selenium Standalone Server then start it (adjust the version):

$ java -jar selenium-server-standalone-2.48.2.jar

You may now start a session, which will launch a browser, and start interacting with it:

require "selenium/webdriver"

capabilities = {
  browserName: "firefox",
  platform: "ANY"
}
driver = Selenium::Webdriver.new
session = Selenium::Session.new(driver, capabilities)

session.url = "http://crystal-lang.org/api"
pp session.url # => "http://crystal-lang.org/api"

input = session.find_element(:css, "input[type=search]")
input.send_keys("Client")
sleep 1

search_list = session.find_element(:class_name, "search-list")
types = search_list.find_elements(:css, "li.search-result--type")
pp count = types.size # => 6

session.stop
