The script in this tutorial in action! The CodeĪs you only need to reload extensions once, I recommend putting it in the before(:all) call. driver.get('chrome-extension://idgpnmonknjnojddfkpgkljpfnnfcklj/popup.html') Return to the Extension’s PageĪgain, referencing the prior tutorial ( Drive Chrome with Extensions using Selenium WebDriver), use the extension’s ID to return to the extension’s page. In the case of multiple extensions you will want to continue using shadow_root2 to locate each extension and their corresponding shadow root. In this scenario, I only had one extension to reload, so I stopped there. reload_button = shadow_root3.find_element(:tag_name, 'cr-icon-button') reload_button.click # click first reload button What if I have more than one extensions to reload? It is important to note that we get our inner shadow root from it’s direct shadow root parent (or driver if it is the outermost).įinally, within our focused shadow root, shadow_root3, we can click the reload button to reload our extension. # first shadow root, call from driver elem1 = driver.find_element(:tag_name, 'extensions-manager') shadow_root1 = driver.execute_script('return arguments.shadowRoot', elem1) # second shadow_root, call from shadow_root1 elem2 = shadow_root1.find_element(:tag_name, 'extensions-item-list') shadow_root2 = driver.execute_script('return arguments.shadowRoot', elem2) # third shadow_root, call from shadow_root2 elem3 = shadow_root2.find_element(:tag_name, 'extensions-item') shadow_root3 = driver.execute_script('return arguments.shadowRoot', elem3) Like the previous tutorial, we will execute JavaScript to isolate the shadow roots but this time do it three times over. Good spotting, but the reload button is not nested under it so we can ignore it for this tutorial.

Some keen readers may notice that there is another shadow root under the tag. In the above screenshot, the reload button is actually under three shadow roots! Chrome Extension Manager page with inspect element’s relevant shadow roots for the reload button highlighted.
