Selenium WebDriver vs Browser version

[victorsa...@gmail.com]

Hi,

I am having a problem of finding browser version compatibility with selenium webDriver. For an example :

1. How do I know selenium webDriver 2.50.0 supports what version of Firefox or google chrome?

2. How do I know selenium standalone server 2.52.0 supports what version of chrome driver?

3. How do I know selenium standalone server 2.52.0 supports what version of c firefox browser and google chrome browser?

I couldn't find this information in the change log. Thanks for your help!

Hi,

Generally, the information on http://www.seleniumhq.org/about/platforms.jsp is correct. The ChromeDriver and MS WebDriver are standalone executables that support the same wire protocol as the standalone server. This means that if you update the chromedriver or MS webdriver executables, they'll support whichever version of those browsers they're designed for.

As an analogue, you can think of the wire protocol used by selenium as if it were HTTP. Provided both the client (your web browser for HTTP, or the language bindings for selenium) speak the same version of the wire protocol to the remote end (the web server for HTTP, or the selenium server driving  the browser itself for selenium) you'll be fine. 

For a long time, we had native components in the firefox driver which meant that we needed to release a new version of selenium when that was released. With geckodriver, this is no longer the case, so the concept of the protocol is even more correct now :)

Hope that helps,

Simon

Caveat : for the last three major versions of Firefox (48, 49, 50) it's essentially been impossible to test using Selenium, WebDriver having been deprecated and Marionette/Gecko not being feature complete WRT WebDriver.

Your options are basically i) not testing on Firefox, just test on Chrome and hope it works ii) Install Firefox 47.0.1 for testing and hope it still works in a current version.
