    Description

      We're using Selenium for automation with QtWebEngine 5.15. Ran into an issue where our application starts normally, but the Chromedriver crashes with an "Unrecognized Chrome Version" error.

       

      I've attached a simple QT App and Selenium java program to repro the issue. I've also attached the java file to show the Selenium code used.

      To repro:

      • Unzip and build the SimpleQtHtmlPage application, then run it
      • Unzip the Java jar, put it in the same folder as the chromdriver.exe and run
      java -jar <path to jar>

       Expected: Chromedriver can connect successfully to the WebEngine

      Actual:  Chromedriver is not able to connect, with the following error:

      Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: cannot connect to chrome at localhost:9222
      from unknown error: unrecognized Chrome version: SimpleQtHtmlPage/
      

      The workaround we've found is to set the QApplication ApplicationName to "Chrome" and ApplicationVersion to "80.0.3987.163". This is a regression as it was not necessary in previous versions of using these softwares together, we have successfully used Selenium for automation with QT 5.10 

       

      ContentBrowserClient::GetProduct was added for compatibility with Chromium 73, in this change]

      Chromium sets the browser version by calling GetProduct, which returns ApplicationName/ApplicationVersion. The chromium code is here

       

      In our actual application, we cannot change our ApplicationName and ApplicationVersion, so we've added code to ContentBrowserClient::GetProduct to return "Chrome/CHROMIUM_VERSION" if an environment variable is set, which means that it's being run using automation.

       Is there a way to set the Browser name/version, without changing QApplication::ApplicationName and QApplication::ApplicationVersion?
