Scripting - Watir/Selenium - Miscellaneous

Set path to chromedriver
Usually the location of chromedriver.exe is added to environmental variable PATH, but sometimes if a different version of chromedriver is needed, it can be specified as following:
(Watir)

chromedriver_path = File.join(File.absolute_path('.', File.dirname(__FILE__)),"chromedriver.exe") 
browser = Watir::Browser.new :chrome, driver_path: chromedriver_path
# Or with some options like following
browser = Watir::Browser.new :chrome, driver_path: chromedriver_path, :switches => %w[--disable-extensions]

Switch to Another Window Opened from Primary One
When a new window is opened from the primary one, the following can be used to switch to the new one:
browser1.window(:index => 1).some_method() 
Or
browser1.window(:title => title_secondary_window).use do
  browser1.some_method()
end

Use execute_script

Some tasks can be performed via

  browser.execute_script(javascript_text, *arguments)
