Selenium WebDriver with Ruby: Examples and General Reference

Last updated:

select an option from a dropdownlist / select input

In order to select the option that reads "some text" from the dropdownlist whose id is my-dropdown:

DRIVER = Selenium::WebDriver.for :firefox
option = => "#my-dropdown"))
option.select_by(:text, "some text")

wait for a page to load

Wait for a page to load. If it takes more than the time passed as argument (the timeout) for the page to become available, an error is raised.

DRIVER = Selenium::WebDriver.for :firefox
wait = => 3)
wait.until { DRIVER.current_url=='http://some_url'}

click ok / accept on an alert dialog

DRIVER = Selenium::WebDriver.for :firefox

find out whether an element is present on the page

use function find_elements rather than find_element because if an element isn't found the first function raises an error:

DRIVER = Selenium::WebDriver.for :firefox
if DRIVER.find_elements(:css,"your selector").empty?
    # nothing here
    # element found

run javascript

DRIVER = Selenium::WebDriver.for :firefox
result = DRIVER.execute_script('return "foo"')
# result now holds "foo"
result2 = DRIVER.execute_script('$("#my_text_input").val());
# result2 now holds whatever text was in your text input

find an element within another element

In other words, run a scoped query in an Element (you want to find all <p> elements within your #my-div div):

DRIVER = Selenium::WebDriver.for :firefox
outer_div = DRIVER.find_element(:css,"#my-div")
p_elements = outer_div.find_elements(:css,"p")
# you can run find_element / find_elements on a single Element!
