gem 'selenium-webdriver'

seleniumn webdriver is really simple. It has only simple operations like:

element = driver.find_element(:id, "q")
element = driver.find_element(:class, 'highlight-java')
element = driver.find_element(:tag_name, 'div')
element = driver.find_element(:name, 'search')

# <a href="http://www.google.com/search?q=cheese">cheese</a>
element = driver.find_element(:link, 'cheese')

# <a href="http://www.google.com/search?q=cheese">search for cheese</a>
element = driver.find_element(:partial_link_text, 'cheese')

element = driver.find_element(:xpath, '//a[@href='/logout']')

# example html
# <div id="food">
#   <span class="dairy">milk</span>
#   <span class="dairy aged">cheese</span>
# </div>

element = driver.find_element(:css, #food span.dairy)

#multiple
element = driver.find_elements(:css, "stuff").each do |el|
  #..
end

operations on Element ar also limited

element = driver.find_element(:id, "q")
element.click
element.attribute('value')
element.text
element.find_elements(:css, "stuff").each do |inner_el|
  inner_el.click if inner_el.text.match(/whatever/)
end

You cannot change element values (eg add style code to highlight)

Examples

# spec/spec_helper.rb
RSpec.configure do |config|
  config.before(:all) do
    options = Selenium::WebDriver::Firefox::Options.new()
        #args: [
        # -headless,
        # -start-maximized,
        #]

    @driver = Selenium::WebDriver.for :firefox, options: options

    target_size = Selenium::WebDriver::Dimension.new(1024, 768)
    @driver.manage.window.size = target_size
    @driver.manage.timeouts.implicit_wait = 5
    @driver.manage.timeouts.page_load = 15
  end

  config.after(:all) do
      @driver.quit
  end
end

    element = @driver.find_element(:class, "error")
    elementText = element.text
    expect(elementText).to include ("Your username is invalid!")
  end
