Take the Chrome version number, remove the last part, and append the result to URL " ".First, find out which version of Chrome you are using.Luckily, the ChromeDriver website provides a systematic way of downloading the correct version of the ChromeDriver given a specific version of Google Chrome. How to download the correct version of Chrome # Even worse, the failure of these tests may be connected to email, SMS, and/or phone alerting systems. But doing this manually every time Chrome updates will quickly become unmanageable.Įspecially when you run UI tests on multiple servers, on a periodic basis, or inside a continuous integration and deployment pipeline.
The fix is pretty simple, go back to the ChromeDriver website and download the most recent version. When the ChromeDriver is incompatible with the installed version of Google Chrome, you will run into the error above. Google Chrome is very good about updating very frequently, often leaving the ChromeDriver out of date.

In this analogy, the consumers are your UI testing code instructing the webdriver, the taxi driver is the webdriver, and the web browser is the vehicle.ĬhromeDriver is the webdriver implementation for Google Chrome. The taxi driver knows how to drive the vehicle towards the instructed location. The consumers don't know how to drive themselves, and instead provide the desired location to the driver. The UI testing technology will communicate with a " webdriver" which will, in turn, drive around the browser.Īn analogy: Consumers without a driver's license use a taxi to go to a specific location.
You can run automated UI browser tests using technologies like Selenium.
