How to test chrome extensions?

Question

Is there a good way to do this? I\'m writing an extension that interacts with a website as a content script and saves data using localstorage. Are there any tools, framework

Answer 1

I found that I can use Selenium web driver for starting fresh browser instance with preinstalled extension and pyautogui for clicks - because Selenium cannot drive "view" of the extension. After clicks you can make screenshots and compare them with 'expected' ones, expecting 95% of similarity (because on different browsers it is acceptable markup movements to a few pixels).
