System.InvalidOperationException: session not created: This version of ChromeDriver only supports Chrome version 74 ChromeDriver and Selenium work together very well, but given enough time you will run into the following error: Unhandled exception. The UI testing technology will communicate with a ' webdriver' which will, in turn, drive around the browser.ĬhromeDriver is the webdriver implementation for Google Chrome. EDIT: Headless Chrome is shipping in Chrome 59 so the need to use the full Canary path will eventually go away.You can run automated UI browser tests using technologies like Selenium. You can check your Chrome version in the menu under Help > About Google Chrome. This walkthrough shows you how to get headless Chrome up and running on OSX and explains in detail how to use the code examples provided by the Chrome team. Headless mode in Chrome is a new way to interact with websites without having to actually have a window up on the screen. This might seem like a trivial improvement but it is actually a huge step forward for scraping data from the web.

Currently there are number of stable but informal solutions to scraping such as PhantomJS or NightmareJS (which is written in Electron). Neither or these tools is going away (edit: the PhantomJS sole maintainer has resigned) and they’re still great solutions to scraping.

If you have existing systems that are working using these tools, you can keep using them. With that said, some users have run into trouble working with PhantomJS and Nightmare. Both have caveats when running on a shell-only system (one without an actual screen or window manager).
