How to Open a Google Chrome with extension in Selenium?

Question

I have been searching for this for a while. I need to open Google Chrome with extension in selenium. The extension should be added from the Web Store and not using .crx file.

I have gone through many websites. Like this website that shows the two ways of doing it. By using the second way I'm able to launch the chrome by hard coding the path but I need to do it the first way so I can make it dynamic.

Below is the code which I have tried, using --user-data-dir property of chrome but it is not opening the browser with extension.

PS: I know that this can be done using .crx file but I need to add the extension from Chrome Store only.

Thanks in advance.

ChromeOptions opt1 = new ChromeOptions();
System.setProperty("webdriver.chrome.driver", "./Win/Drivers/chromedriver.exe");
opt1.addArguments("--user-data-dir = C:\\Sanity\\Chrome");
driver = new ChromeDriver(opt1);
driver.get("https://www.google.com");

Answer 1

Using pre-configured profile

opt.add_argument('user-data-dir=folder')

where folder is the location of the chrome profile you're interested in (without any spaces before / after '=' sign preceding it - and check the location of the profile e.g. C:\Sanity\Chrome\User Data\Profile1)

Using 'hard coding'

opt1.add_argument('--load-extension={folder path with manifest here}')

(again, no spaces)

opt.add_extension('{crx path here}')

Mechanical way

What confues me is that you've emphasied 'from the webstore' a couple of times. The only way I know how to download directly from webstore (i.e. after launching chrome/webdriver) is with following type of code (which makes use of Pyautogui extensively, and is less 'savvy' then your ordinary way of doing it)..

PS - I honestly think that if you just fixed your spelling/syntax with the code you're currently using, you'll be fine - some feedback in this regard would be useful btw....
