Web Automation Testing Tips – iFrame handling

The article is going to explain how to click a button located within iFrame, and how to get the window title of new launch window.

As we know that if a web element is located within iframe, selenium will encounter exception “element not found” while trying to click the button. Therefore, we must locate the iframe first before locating the button to click.

Testing Scenario

1. Go to http://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_win_open

2. click “Try It”

3. Print the Window Title of original Window and New Window


Locate the iFrame first

To locate the iframe, here is the sample code where “iframeResult” is ID of the iframe. We can inspect the iframe ID by Firefox FireBug. Then, once we locate the iframe, we may switch to the target frame by using the “switch_to.frame”

frame_btn = self.driver.find_element_by_id(“iframeResult”) self.driver.switch_to.frame(frame_btn)


Click the Button

Once the iframe is located, we may click the TryIT button. In this example, we locate the button by XPath “/html/body/button”.

We may inspect the Xpath by using FireFox addon FireBug and FirePath. Since the HTML button element doesn’t define any name or class. Therefore, Xpath is the optimal approach to locate the “Try it” button.Locate_button_Xpath

#locate the “Try it” button by Xpath TryItButton = self.driver.find_element_by_xpath(“/html/body/button”)# click the “Try it” Button TryItButton.click()

 Switch to New Window

Once the “Try it” is clicked, it will launch a new window with window title “W3schools Online Web Tutorials”.

How do we switch to the new launched window and get the window title?

We must get the window handle first. then, use “switch_to.window”.

In this case, handle[0] is the original window where we click the TryIt button.

handle[1] is the newly launched Window with title “W3schools Online Web Tutorials”

handle = self.driver.window_handlesself.driver.switch_to.window(handle[1])print ” new window title =” + self.driver.title

        #1 Assign to current Window Handle and print
        handle = self.driver.window_handles

        #2 self.driver.switch_to_window(handle)
        print "Initial Window title =" +  self.driver.title

        #3 Locate the Class name of the frame where we can click the button
        frame_btn = self.driver.find_element_by_id("iframeResult")

        #4 Switch to the target frame where the click button "Try it" is

        #5 locate the "Try it" button by Xpath
        TryItButton = self.driver.find_element_by_xpath("/html/body/button")
        # click the "Try it" Button

        handle = self.driver.window_handles
        print "After clicking TryIT, new window title =" +  self.driver.title

        #Close the New window

    def tearDown(self):
