In this blog, you’ll find out how to scroll down or up so as to display additional information present on the online page.
Let us consider a test suit during which we’ll automate the subsequent scenarios:
• Invoke Firefox browser
• Open URL: www.tecklearn.com
• Scroll down through the online page so as to point out the Java Technology section
We will create our test suit step by step so as to offer you an entire understanding of the way to scroll an internet page using “scrollBy” method of JavaScript.
Step1. Launch Eclipse IDE and open the prevailing test suite “Demo_Test” which we’ve created in earlier sessions of this tutorial.
Step2. Right click on the “src” folder and make a replacement Class File from New >Class.

Give your Class name as “Scroll_Test” and click on on “Finish” button.

Step3. Let’s get to the coding ground.
• To invoke Firefox browser, we’d like to download Gecko driver and set the system property for Gecko driver. we’ve already discussed this in earlier sessions of this tutorial. you’ll refer “Running test on Firefox Browser” to find out the way to download and set System property for Firefox driver.
Here is that the sample code to line system property for Gecko driver:

1. // System Property for Gecko Driver
2. stem.setProperty("webdriver.gecko.driver","D:\\GeckoDriver\\geckodriver.exe" );

• After that we’ve to initialize Gecko Driver using Desired Capabilities Class.
Here is that the sample code to initialize gecko driver using DesiredCapabilities class.

1. // Initialize Gecko Driver using Desired Capabilities Class
2. DesiredCapabilities capabilities = DesiredCapabilities.firefox();
3. capabilities.setCapability("marionette",true);
4. ebDriver driver= new FirefoxDriver(capabilities);

Combining both of the above code blocks, we’ll get the code snippet to launch Firefox browser.

1. // System Property for Gecko Driver
2. System.setProperty("webdriver.gecko.driver","D:\\GeckoDriver\\geckodriver.exe" );
3.
4. // Initialize Gecko Driver using Desired Capabilities Class
5. DesiredCapabilities capabilities = DesiredCapabilities.firefox();
6. capabilities.setCapability("marionette",true);
7. WebDriver driver= new FirefoxDriver(capabilities);

• After that we’d like to write down the code which can automate our second test scenario (navigate to the specified URL)
Here is that the sample code to navigate to the specified URL:

1. // Launch Website
2. navigate().to("www.tecklearn.com");
The complete code till now will look something like this:
1. import org.openqa.selenium.WebDriver;
2. import org.openqa.selenium.firefox.FirefoxDriver;
3. import org.openqa.selenium.remote.DesiredCapabilities;
4.
5. public class Scroll_Test {
6.
7. public static void main(String[] args) {
8.
9. // System Property for Gecko Driver
10. System.setProperty("webdriver.gecko.driver","D:\\GeckoDriver\\geckodriver.exe" );
11.
12. // Initialize Gecko Driver using Desired Capabilities Class
13. DesiredCapabilities capabilities = DesiredCapabilities.firefox();
14. capabilities.setCapability("marionette",true);
15. WebDriver driver= new FirefoxDriver(capabilities);
16.
17.
18. // Launch Website
19. driver.navigate().to("www.tecklearn.com");
20.
21. }
22.
23. }

Step4. To automate our third test scenario, we’d like to write down the code which can scroll down the webpage so as to point out the Java Technology section present on the Tecklearn website.
To scroll an internet page, we’ve to use the scrollBy method of JavaScript. For executing the JavaScript method we’ll use JavaScript executor. The scrollBy method takes two parameters one each for horizontal and vertical scroll in terms of pixels.

1. JavascriptExecutor js = (JavascriptExecutor)driver;
2. js.executeScript("scrollBy(0, 4500)");
Thus, our final test script will look something like this:
1. import org.openqa.selenium.JavascriptExecutor;
2. import org.openqa.selenium.WebDriver;
3. import org.openqa.selenium.firefox.FirefoxDriver;
4. import org.openqa.selenium.remote.DesiredCapabilities;
5.
6. public class Scroll_Test {
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.
19. // Launch Website
20. driver.navigate().to("www.tecklearn.com");
21.
22. //Scroll down the webpage by 4500 pixels
23. JavascriptExecutor js = (JavascriptExecutor)driver;
24. js.executeScript("scrollBy(0, 4500)");
25.
26. }
27. }

Upon execution, the above test script will launch the Firefox browser and automate all the test scenarios.
