Question

I am trying to build a mouse for Firefox Webdriver in Ruby: no success so far.

@driver = Selenium::WebDriver.for :firefox, :profile => profile
@mouse = Selenium::WebDriver::Mouse.new(@driver)
@mouse.click(@driver.find_element :css => 'li:nth-child(1)')

Traceback of the mistake

test_add_course(ItemAutocompleteTest): 
NoMethodError: undefined method

Thank you for any suggestions!

You’ll notice the Mouse class is marked as private in the docs – it’s not part of the public API. To use the advanced user interactions, you want to look at the ActionBuilder instead, basically:

driver.action.key_down(:shift).
              click(element).
              double_click(second_element).
              key_up(:shift).
              drag_and_drop(element, third_element).
              perform

I’ll add a section about this to the wiki page.
