Java Pre gecko

  • Firefox test with java pre Gecko version
public class FirefoxNoGeckoTest {
	public static void main(String[] args) {
		WebDriver driver = new FirefoxDriver();
		driver.get("http://www.google.com");
	}
}

Java After gecko

  • Firefox test with java pre Gecko version
public class FirefoxGeckoTest {
	public static void main(String[] args) {		System.setProperty("webdriver.gecko.driver","C:\\PathToGecko\\geckodriver.exe");
		WebDriver driver = new FirefoxDriver();
		driver.get("http://www.google.com");
	}
}

Portable Firefox 46 with Marionette Driver

  • Portable Firefox test
System.setProperty("webdriver.gecko.driver", "C:\\PathToGecko\\geckodriver.exe");

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);

FirefoxBinary binary = new FirefoxBinary(new File(firefoxPortablePath));

WebDriver driver = new FirefoxDriver(binary, createFirefoxProfile(), capabilities);
  • Firefox testing code in case of problem
System.setProperty("webdriver.gecko.driver", "C:\\your_directory\\geckodriver.exe");
System.out.println("Setup gecko driver");
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
System.out.println("Prepare capabilities");
capabilities.setCapability("marionette", true);
System.out.println("Start new driver");
WebDriver driver = new FirefoxDriver(capabilities);
System.out.println("Open test page");

Checks

Platforms Supported by Selenium

Due to the high number of version and platforms you need to be sure that what you are using is compatible with Selenium. And be careful because the things are changing very fast in the world of automation testing.

Platforms Supported by Selenium

Check latest Selenium version

  1. Open browser

  2. Visit:

2.1 You needed for Firefox and Chrome
Selenium Java

2.2 Firefox only
Selenium Firefox Driver

2.3 Chrome only
Selenium Chrome Driver

Browser compatibility

You need to check the browser compatibility before opting to test with Selenium:

SeleniumHQ browser compability

This might help to save your precious time. You have to search for something like:

3.4.0

  • Geckodriver 0.16 is strongly recommended
  • LiFT package is now available as a separate maven dependency.
  • Deprecated numerous constructors on RemoteWebDriver that are no longer useful.

Check if Firefox version ( 32-bit or 64-bit)

There are several versions of GeckoDriver depending on OS and 32-bit or 64-bit version. Based on your requirements you can download the corresponding GeckoDriver. Next you can check whether your Firefox is 32-bit or 64-bit.

  1. Open Firefox browser and click on the menu (hamburger icon from the right corner)

  2. Click on Help icon (question mark)

  3. Click on About Firefox. About Mozilla Firefox popup would be displayed

  4. Check if Mozilla Firefox is 32-bit or 64-bit

More info : Find what version of Firefox you are using

Check if Firefox is portable

  1. Windows Start menu

  2. Control Panel

  3. Programs and features

  4. Search Firefox in the program list

Known Selenium Errors

Error 1. Webdriver Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms

Usually the reason for this error is that the version of Selenium Server is not compatible with Firefox and does not know how to work with the newer version of Firefox.

Solutions

  • Update to newer version of the Selenium Server that supports the newer version of Firefox.
  • check browser compability( the section - checks / Browser compatibility )
  • Downgrade Firefox ( sometimes this is the best option with the least efforts). Here is the list of older versions of firefox: Firefox versions
  • Explicitly block the automated update for Firefox (this will prevent future problems of this kind)

Error 2. Exception in thread “main” Java.lang.IllegalStateException

If you use old version of Firefox 46 and latest version of Selenium (Selenium 3.7.1) then you may face the above mentioned error.

Solution

  • downgrade selenium driver
  • update Firefox version

Error 3. Connect to localhost:28379 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused

Reasons could be:

  • blocked access or unreacheable of the geckodriver.exe.
  • old stuff in Mozilla cache
  • hanging process with old configuration

Solution

  • verify gecko driver location
  • use accessible location for gecko driver ( avoid temp, network drives etc)
  • clean browser cache
  • restart machine in order to clean old processes
