In this blog , we’ll find out how to run your Selenium Test Scripts on Firefox Browser.
Before proceeding with this section, allow us to first understand the fundamentals of Gecko Driver.

What is Gecko Driver?

The term Gecko refers to Gecko browser engine which was developed by Mozilla Foundation as a neighborhood of Mozilla browser.
Gecko Driver is a link between your tests in Selenium and therefore the Firefox browser. It acts as a proxy between W3C WebDriver-compatible clients (Eclipse, Netbeans, etc.) to interact with Gecko-based browser (Mozilla Firefox).
Marionette (the next generation of FirefoxDriver) is turned on by default from Selenium 3. Selenium uses W3C Webdriver protocol to send requests to GeckoDriver, which translates them into a protocol named Marionette. albeit you’re working with older versions of Firefox browser, Selenium 3 expects you to line path to the driving force executable by the webdriver.gecko.driver.
Note: Selenium 3 has upgraded itself to now launch Firefox driver using Marionette driver rather than the default initialisation supported earlier.
Let us consider a test suit during which we’ll attempt to automate the subsequent scenarios in Firefox browser.
• Launch Firefox browser.
• Open URL: www.tecklearn.com
• Click on the Custom Search text box
• Type the worth “Java”
• Click on the Search button.
We will create our second test suit within the same test suite (Demo_Test).
Step1. Right click on the “src” folder and make a replacement Class File from New > Class.
Give your Class name as “Second” and click on on “Finish” button.

Step2. Open URL: https://github.com/mozilla/geckodriver/releases in your browser and click on on the acceptable version for GeckoDriver download supported the OS you’re currently performing on . Here, we are downloading the 64bit version of GeckoDriver for windows.

The downloaded file would be in zipped format. Unpack the contents during a convenient directory.

Before writing the test script, allow us to first understand how we will initialize GeckoDriver in Selenium. There are 3 ways to initialize GeckoDriver:
1. Using Desired Capabilities
First, we’ve to line the system property for Gecko Driver.

1. System.setProperty("webdriver.gecko.driver","D:\\GeckoDriver\\geckodriver.exe" );

Below is that the code to line gecko driver using DesiredCapabilities class.

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

Here is that the complete code:

1. System.setProperty("webdriver.gecko.driver","D:\\GeckoDriver\\geckodriver.exe" );
2. DesiredCapabilities capabilities = DesiredCapabilities.firefox();
3. capabilities.setCapability("marionette",true);
4. WebDriver driver= new FirefoxDriver(capabilities);

2. Using marionette property:
Gecko Driver also can be initialized using marionette property.

1. System.setProperty("webdriver.firefox.marionette","D:\\GeckoDriver\\geckodriver.exe");

The code for Desired Capabilities isn’t required for this method.
3. Using Firefox Options:
Firefox 47 or later versions have marionette driver as a legacy system. Thus, marionette driver are often called using Firefox Options as shown below.

1. FirefoxOptions options = new FirefoxOptions();
2. options.setLegacy(true);

Step3. Now it’s time to code. we’ve embedded comments for every block of code to elucidate the steps clearly.

1. import org.openqa.selenium.By;
2. import org.openqa.selenium.WebDriver;
3. import org.openqa.selenium.firefox.FirefoxDriver;
4. import org.openqa.selenium.remote.DesiredCapabilities;
5.
6. public class Second {
7.
8. public static void main(String[] args) {
9.
10. // System Property for Gecko Driver
11. System.setProperty("webdriver.gecko.driver","D:\\GeckoDriver\\geckodriver.exe" );
12.
13. // Initialize Gecko Driver using Desired Capabilities Class
14. DesiredCapabilities capabilities = DesiredCapabilities.firefox();
15. capabilities.setCapability("marionette",true);
16. WebDriver driver= new FirefoxDriver(capabilities);
17.
18. // Launch Website
19. driver.navigate().to("http://www.tecklearn.com/");
20.
21. // Click on the Custom Search text box and send value
22. driver.findElement(By.id("gsc-i-id1")).sendKeys("Java");
23.
24. // Click on the Search button
25. driver.findElement(By.className("gsc-search-button gsc-search-buttonv2")).click();
26. }
27.
28. }

Step4. Right click on the Eclipse code and choose Run As > Java Application.

Step5. The output of above test script would be displayed in Firefox browser.
