How to Automate a Login Page by Playwright Java

 

Before writing the script, ensure you have:

• Java installed (JDK 11 or above)
• Maven or Gradle project setup
• Playwright for Java dependency added

Add maven dependency in pom.xml:

<dependencies>
    <dependency>
        <groupId>com.microsoft.playwright</groupId>
        <artifactId>playwright</artifactId>
        <version>1.44.0</version>
    </dependency>
</dependencies>

Java Code to Automate Login

import com.microsoft.playwright.*;

public class OrangeHRMLoginTest {
    public static void main(String[] args) {
        // Step 1: Launch Playwright
        try (Playwright playwright = Playwright.create()) {

            // Step 2: Launch a browser (Chromium)
            Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false));

            // Step 3: Create a new browser context
            BrowserContext context = browser.newContext();

            // Step 4: Open a new page
            Page page = context.newPage();

            // Step 5: Navigate to the login page
            page.navigate("https://opensource-demo.orangehrmlive.com/web/index.php/auth/login");

            // Step 6: Wait for username input field to be visible
            page.waitForSelector("input[name='username']");

            // Step 7: Fill in the login credentials
            page.fill("input[name='username']", "Admin");
            page.fill("input[name='password']", "admin123");

            // Step 8: Click the login button
            page.click("button[type='submit']");

            // Step 9: Print login success message
            System.out.println("Login successful!");

            // Optional: Close browser after verification
            browser.close();
        }
    }
}

Code Explanation:

Line/Block	Explanation
Playwright.create()	Starts Playwright engine
chromium().launch(...)	Launches Chromium browser (can be firefox() or webkit() too)
browser.newContext()	Creates a new isolated browser context (like incognito)
context.newPage()	Opens a new browser tab/page
page.navigate(url)	Opens the specified URL
page.fill(selector, value)	Enters value into input field (selector is a CSS locator)
page.click(selector)	Clicks the element (e.g., login button)
browser.close()	Closes the browser at the end

Required Credentials

For this demo:

• Username: Admin

• Password: admin123

Points to Consider:

• This script assumes that the page loads fast enough, but for real-world tests, you should use explicit waits where needed.

• You can run this from a main method or integrate it into a test framework like JUnit/TestNG for proper test cases.
