Selenium Webdriver - Need to enable chrome extension while launching the browser

You may refer with this documentation on how to start the Chrome Browser with Extensions.

1.Use a Custom Chrome Profile

• Add the needed settings to the Selenium code:

Here:

public class TestClass { WebDriver driver; @Before public void setUp() { System.setProperty(“webdriver.chrome.driver”, “C:\\Selenium\\BrowserDrivers\\chromedriver.exe”); ChromeOptions options = new ChromeOptions(); options.addArguments(“user-data-dir=C:\\Selenium\\BrowserProfile”); options.addArguments(“–start-maximized”); driver = new ChromeDriver(options); } @After public void tearDown() { driver.quit(); } @Test public void testScript() { Thread.sleep(10000); } } 

2.Load a Chrome Extension

• Add the needed settings to the code:

Here:

public class TestClass { WebDriver driver; @Before public void setUp() { String pathToExtension = “C:\\Users\\home\\AppData\\Local\\Google\\Chrome\\User Data\\Default\\Extensions\\mbopgmdnpcbohhpnfglgohlbhfongabi\\2.3.1_0”; ChromeOptions options = new ChromeOptions(); options.addArguments(“–load-extension=” + pathToExtension); driver = new ChromeDriver(options); } @After public void tearDown() { driver.quit(); } @Test public void testScript() { Thread.sleep(10000); } }

Caveat

Would recommend doing this only when testing your own extensions - i.e. your responsibility to ensure you do not infringe upon usage rights / T&Cs - in accordance with the provider's legal terms / expectations etc.

As such, response below is somewhat 'generic' / in context of testing your own extension - however, there is brief consideration / exploration of the element you were interested in, purely for academic / theoretical interest

Summary

1. Pre-requisites: driver with extension installed
2. Open 'chrome-extension://UNIQUE_ID/popup/popup.html' (this may vary from extension to extension, see ref in part B below)
3. Inspect elements for testing as req.

Code / Desc

(skip to B-C for the bit you're after)

A) Basics (imports, driver, install extension)

from selenium import webdriver from selenium.webdriver.chrome.options import Options from os import path path_core = os.path.join(os.path.expanduser("~"), 'Projects', 'Testing') path_exec = os.path.join(path_core, "chromedriver.exe") path_ext = os.path.join(path_core, 'extension.CRX') 

Notes: path_core, path_exec, and path_ext are respective locations for: your code, chromedriver.exe file, and extension (crx for your extension)

o = Options() o.add_extension(path_ext) d = webdriver.Chrome(executable_path = path_exec, options = o) 

Webpage with extension should be installed.

B) Open popup as a webpage

d.get('chrome-extension://UNIQUE_ID/popup/popup.html') 

Ref/based upon: E. Shani - where UNIQUE_ID is specific to the extension, and popup/popup.html may vary from extension to extension too...

You can then test your extension by interacting with it in the same way you would an ordinary webpage (assuming this functionality 'features')

C) Interact

Inspecting elements is generally straightforward - as an e.g., I had a brief look at the element you were interested in and managed to find it with JQuery / console as follows:

document.querySelector('page-switch').shadowRoot.querySelector('main-index').shadowRoot.querySelector('c-switch') 

Appreciate this doesn't exactly answer your Q, but do hopes it serves as a useful guide when it comes to your own testing/extensions!
