How To Zoom In And Zoom Out Browser In Selenium WebDriver

How To Zoom In And Zoom Out In Selenium

We all know Selenium automates browsers. When we are running selenium scripts, sometimes we may face a situation where we need to perform zoom in and zoom out. In Selenium, this can be easily achieved. In this article, I will show you two methods on how to Zoom In and Zoom Out in Selenium WebDriver.

Manually, we have to press CTRL+ADD to do Zoom In and we have to press CTRL+SUBTRACT to do zoom out. I have tested both the below methods i.e., how to zoom in and zoom out on firefox.

Method 1: Using Robot Class

package stm;
import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Test;
public class zoomInZoomOut {
	@Test
	public void googleSearchTest() throws AWTException, InterruptedException{
	
		System.setProperty("webdriver.gecko.driver", System.getProperty("user.dir")+"\\src\\test\\java\\drivers\\geckodriver.exe");
		WebDriver driver = new FirefoxDriver();
		driver.get("https://www.softwaretestingmaterial.com");
		driver.manage().window().maximize();
		Thread.sleep(5000);
		System.out.println("zooming");
		
		Robot robot = new Robot();
		System.out.println("About to zoom in");
		for (int i = 0; i < 3; i++) {			
			robot.keyPress(KeyEvent.VK_CONTROL);
			robot.keyPress(KeyEvent.VK_ADD);
			robot.keyRelease(KeyEvent.VK_ADD);
			robot.keyRelease(KeyEvent.VK_CONTROL);
		}
		Thread.sleep(5000);
		System.out.println("About to zoom out");
		for (int i = 0; i < 4; i++) {
			robot.keyPress(KeyEvent.VK_CONTROL);
			robot.keyPress(KeyEvent.VK_SUBTRACT);
			robot.keyRelease(KeyEvent.VK_SUBTRACT);
			robot.keyRelease(KeyEvent.VK_CONTROL);
		}
	}
}

We can perform page zoom action using sendKeys method.

Method 2: Using SendKeys Method

package stm;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Test;
public class zoomInZoomOut {
	@Test
	public void googleSearchTest() throws InterruptedException{
		System.setProperty("webdriver.gecko.driver", System.getProperty("user.dir")+"\\src\\test\\java\\drivers\\geckodriver.exe");
		WebDriver driver = new FirefoxDriver();
		driver.get("https://www.softwaretestingmaterial.com");
		driver.manage().window().maximize();
		Thread.sleep(5000);
		System.out.println("zooming");
		// To zoom in 3 times
		for(int i=0; i<3; i++){ 
			driver.findElement(By.tagName("html")).sendKeys(Keys.chord(Keys.CONTROL,Keys.ADD));
		}
		// To zoom out 3 times
		for(int i=0; i<3; i++){
			driver.findElement(By.tagName("html")).sendKeys(Keys.chord(Keys.CONTROL,Keys.SUBTRACT));
		}
		//To set the browser to default zoom level ie., 100%
		driver.findElement(By.tagName("html")).sendKeys(Keys.chord(Keys.CONTROL, "0"));
	}
}
