Maximize Browser Window – Selenium Java

Maximize Browser Window

To maximize browser window programmatically using Selenium in Java, use WebDriver.manage().window().maximize() function.

WebDriver.manage().window().maximize() maximizes the current window if it is not already maximized.

The following is a simple code snippet to initialize a web driver and maximize the window.

WebDriver driver = new ChromeDriver();
driver.manage().window().maximize();

Example

In the following program, we write Java code to initialize a web driver, maximize the window, and open a URL.

Java Program

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class MyAppTest {
    public static void main(String[] args) {
        System.setProperty("webdriver.chrome.driver", "/usr/local/bin/chromedriver");  
    	WebDriver driver = new ChromeDriver();
        driver.get("https://www.google.com/ncr");
    	driver.manage().window().maximize();
        driver.quit();
    }
}
