Important changes in Selenium 3.0

* Minimum java version is now 8+
* The original RC APIs are only available via the leg-rc package.
* To run exported IDE tests, ensure that the leg-rc package is on the classpath.
* Support for Firefox is via Mozilla’s geckodriver.
* Support for Edge is provided by MS:
* Official support for IE requires version 9 or above
* New html-table runner backed by WebDriver.
* Unused command line arguments are now no longer parsed.

Now let us see the example to launch firefox browser with Selenium 3 using gecko driver.

package com.test;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Test;

public class ExampleThree {

String driverPath = “<path to gecko driver executable>”;
public WebDriver driver;

@Test
public void launchBrowser() {
System.out.println(“launching firefox browser”);
System.setProperty(“webdriver.gecko.driver”, driverPath+”geckodriver.exe”);
driver = new FirefoxDriver();
}

@Test
public void openApplication() {
driver.navigate().to(“http://www.google.com&#8221;);
}

@Test
public void closeDriver() {
if(driver!=null) {
driver.close();
}
}
}

To run tests on remote machines, WebDriver has to use the instance of the RemoteWebDriver and DesiredCapabilities in order to specify browser name, version and platform to execute tests.

Generally to run tests on our local machine, we will just specify as WebDriver driver = new FirefoxDriver(); to run on Firefox browser.

To execute tests on remote machine, we need to use remotewebdriver, below is the sample code to execute your tests on remote machine with Firefox gecko driver

System.setProperty(“webdriver.gecko.driver”, driverPath+”geckodriver.exe”);
DesiredCapabilities capabilities=DesiredCapabilities.firefox();
capabilities.setCapability(“marionette”, true);
WebDriver driver = new FirefoxDriver(capabilities);
The above code is verified with selenium-server-standalone-3.0.0-beta2 and Firefox 48 version. Please let me know if you have any issues.

In your Maven project, just add / update the following selenium dependency to your pom.xml:

<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.0.0-beta2</version>
</dependency>
The most common issue people are facing with latest versions of Firefox is org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms.

Users who are facing the above problem, Please use Marionette (geckodriver).

Please do comment your issue / observation with the versions (Selenium, Firefox and Geckodriver) that you have used.
