Selenium 3.3.1, Gecko Driver 0.15.0, Firefox 42

[Gregma]

Can the above work?  I need to do testing both on the most recent firefox build and older builds back to build 42.  All with Selenium 3.3.x.

No, it won't work. Only Firefox 48 and on are supported: https://github.com/mozilla/geckodriver/blob/master/README.md

Then how are those companies that still need to support older firefox builds supposed to test on those older builds?  Have two completely separate Selenium code bases?

Thanks!

No, the right thing to do there is to set the capability named `marionette` to `false` for running against older versions of firefox. The language bindings should do the right thing and bypass the use of geckodriver at all, using instead the legacy Firefox driver that works with versions 47 and below of the driver. It's a simple configuration change when you start your session. The details of how that capability gets set may differ depending on what language you use, but the principle is the same.

I actually tried that, however, got this exception when instantiating the webdriver.

java.lang.ClassCastException: org.openqa.selenium.remote.service.DriverCommandExecutor cannot be cast to org.openqa.selenium.firefox.FirefoxDriver$LazyCommandExecutor

Here is the code:

String firefoxLocation = System.getenv("ProgramFiles") + "\\Mozilla Firefox_42\\firefox.exe";

String geckoLocation = "..\\framework-test\\gecko\\geckodriver_15.exe";

try

{

//Lets determine what browser we will be using, then load the appropriate driver

switch (browser.toLowerCase())

{

case "firefox" :

{

System.setProperty("webdriver.gecko.driver", geckoLocation);

System.setProperty("webdriver.firefox.bin", firefoxLocation);

System.setProperty("webdriver.reap_profile", "false");

//Set the capabilities

DesiredCapabilities dc = DesiredCapabilities.firefox();

dc.setCapability("marionette", false);

dc.setCapability("acceptSslCerts", true);

dc.setCapability("acceptInsecureCerts", true);

//Set the profile

FirefoxProfile profile = new FirefoxProfile();

profile.setAcceptUntrustedCertificates(true);

profile.setAssumeUntrustedCertificateIssuer(true);

//Disable Firefox Auto-Updating

profile.setPreference("app.update.auto", false);

profile.setPreference("app.update.enabled", false);

dc.setCapability(FirefoxDriver.PROFILE, profile);

driver = new FirefoxDriver(dc);

Log.info("*****Opened Firefox");

break;

}

case "chrome" :

{

System.setProperty("webdriver.chrome.driver", "libs//chromedriver.exe");

driver = new ChromeDriver();

break;

}

}

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

driver.manage().window().maximize();

}

catch (Exception e)

{

Log.info("Class Utils | Method OpenBrowser | Exception desc : " + e.getMessage());

Log.error("Class Utils | Method OpenBrowser | Exception desc : " + e.getMessage());

}

return driver;

Thanks!
