This article would be helpful if you develop Chrome extension and you need automation testing to reduce cost of testing. We try to automate functional testing of Chrome extension with Selenium WebDriver. On the other hand it may look impossible to automate as Selenium works only with webUI and to manipulate Chrome extension should be used GUI testing tool similar to ldtp. You can use any GUI automation testing tool to test Chrome extension but if you need also test webUI solution would be complex. Let’s start.
By default Selenium can’t manipulate Chrome extension and we should open it in webUI. To open extension in webUI you can use such url:
