Playwright enables reliable end-to-end testing for modern web apps
Playwright is a robust web automation tool that supports multiple browsers (Chromium, Firefox, and WebKit) and runs on diverse platforms (Windows, macOS, and Linux) using a single API. This flexibility allows developers to write consistent and reliable scripts for testing and automation without worrying about browser-specific implementations or platform constraints. By utilising Playwright, developers can streamline their workflows, ensuring their web applications work seamlessly across different environments, ultimately improving efficiency and reducing the time needed for cross-browser testing.
Cross-browser : Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox.
WebKit : is one of the browser engines supported by Playwright, alongside Chromium and Firefox. It is the engine that powers Apple’s Safari browser. In Playwright, WebKit provides the ability to automate and test web applications in a browser environment that closely mimics Safari, ensuring compatibility and consistency for web applications on macOS and iOS platforms.
Cross-platform : Test on Windows, Linux, and macOS, locally or on CI, headless or headed.
Cross-language : Use the Playwright API in TypeScript, JavaScript, Python, .NET, Java.
Test Mobile Web : Native mobile emulation of Google Chrome for Android and Mobile Safari. The same rendering engine works on your Desktop and in the Cloud.
Before we proceed make sure your java is configured in your laptop without which Playwright will not work. If you are new to java and nut yet sure how to do it do checkout below Blog
First download the eclipse from here
Step 1: Go to google and type eclipse free download as shown below
Step 2: Click on 1st link after which click on the download button
Step 3: Again click on the download button
Step 4: As shown below download has finally started
Step 5: Install the downloaded eclipse
Step 6: FInally welcome page will come kindly close it as shown below
Step 7: Now click on File on left stop corner
Step 8: Click on New->Project
Step 9: Click on Maven Project and click Next button
Step 10: Click on the next button
Step 11:Click on the filter and type “maven-archetype-quickstart” version 1.4
Step 12:
Step 13:
Step 14: Click on the POM.XML
Step 15: Copy the below xml file and paste it inside the POM.xml[Save it]

Step 16:
Step 17:
Step 18: Make sure your JRR is above 1.8 else you will get compile time error as shown below
Step 19: In order to do that do right click on JRE System Library and click on properties
Step 20: Click on Execution Environment and select JRE version 17.
Step 21: Now Copy the below code and paste in your class
package PlayWright_Package.PlayWright_Project;
import com.microsoft.playwright.Browser;
import com.microsoft.playwright.BrowserType;
import com.microsoft.playwright.BrowserType.LaunchOptions;
import com.microsoft.playwright.Page;
import com.microsoft.playwright.Playwright;
public class Java_Playwright_1stprogram {
public static void main(String[] args)
{
Playwright playwright = Playwright.create();
BrowserType firefox = playwright.firefox();
Browser browser = firefox.launch( new LaunchOptions().setHeadless(false));
Page page = browser.newPage();
page.navigate("https://grotechminds.com/registration/");
System.out.println(page.title());
}
}
The meaning of each line is written below:
Playwright playwright = Playwright.create();
//This initializes the Playwright instance, which is necessary to use the library.
BrowserType firefox = playwright.firefox();
Browser browser = firefox.launch( new LaunchOptions().setHeadless(false));
//This launches a new instance of Firefox browser.
//The setHeadless(false) option specifies that the browser should be launched
//in a headful mode, meaning you will be able to see the browser window.
Page page = browser.newPage();
//This creates a new browser page (or tab).
page.navigate("https://grotechminds.com/registration/");
//This instructs the browser to navigate to the specified URL.
System.out.println(page.title());
//This prints the title of the page to the console.
Conclusion:
The provided Java snippet demonstrates how to use the Playwright library to automate a browser task. It shows the steps to create a Playwright instance, launch a Firefox browser, navigate to a specified URL, and print the page title to the console. By following this approach, developers can automate various web tasks and interactions efficiently.
To execute the code successfully, ensure that the Playwright dependencies are correctly added to your project,and necessary browsers are installed, and your development environment is properly configured. This setup enables the effective use of Playwright for web automation tasks in Java applications.
