2. Choose & # 8220; Maven Project & # 8221; and continue to the following step.
3. Select the & # 8220; Quickstart & # 8221; archetype, provide a project name, and click & # 8220; Finish & # 8221;.

POM Configuration:

Add the following dependency to your projection & # 8217; s POM.xml file:

& lt; dependence & gt; & lt; dependency & gt; & lt; groupId & gt; com.microsoft.playwright & lt; /groupId & gt; & lt; artifactId & gt; playwright & lt; /artifactId & gt; & lt; version & gt; 1.10.0 & lt; /version & gt; & lt; /dependency & gt; & lt; /dependencies & gt;

Save the XML file.

Playwright Java Example Code:

import com.microsoft.playwright.Playwright; public stratum Play {public static void master (String [] args) {try (Playwright playwright = Playwright.create ()) {Browser browser = playwright.chromium () .launch (); Page page = browser.newPage (); page.navigate (`` http: //www.browserstack.com/user/login ''); System.out.println (page.title ());}}}

• The code create a Chromium browser instance and a new page within that illustration.
• You navigate to the delimitate site using thepage.navigate () method.
• Finally, we print the page rubric to corroborate that Playwright is installed and functioning as expected.

Writing Test Cases in Java

• Playwright has specializedassertionstailored for the dynamic web, mechanically rehear checks until the weather are met.
• It also compriseauto-wait functionality, waiting for component to become actionable before executing activity.
• Additionally, Playwright provides & # 8220; assertThat & # 8221; overloads for conveniently writing averment.

Here & # 8217; s an example test showcasing the usage of web-first affirmation, locator, and selectors

package org.example; import java.util.regex.Pattern; import com.microsoft.playwright. *; import com.microsoft.playwright.options.AriaRole; import unchanging com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; public stratum App {public static void main (String [] args) {try (Playwright playwright = Playwright.create ()) {Browser browser = playwright.chromium () .launch (); Page page = browser.newPage (); page.navigate (`` https: //www.browserstack.com/guide/writing-cypress-tests ''); assertThat (page) .hasTitle (Pattern.compile (`` Playwright '')); // create a locator Locator getStarted = page.getByRole (AriaRole.LINK, new Page.GetByRoleOptions () .setName (`` Get Started ''));

When expend Playwright, you can use & # 8220; assertThat & # 8221; overloads with a built-in wait mechanics. This entail the assertion will patiently wait until the expected stipulation is fulfilled before proceedings.

It ensures that you can rely on Playwright to handle your tests & # 8217; timing and synchroneity aspects effortlessly.

import java.util.regex.Pattern; import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; assertThat (page) .hasTitle (Pattern.compile (`` Playwright ''));

To enhance your testing capabilities, Playwright offer the flexibility to create custom locators using the Page.locator () method. Access to a wide range of locators, such as role, text, tryout ID, and more.

import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; assertThat (page.locator (`` text=Installation '')) .isVisible ();

Set up Playwright and Java

To set up Playwright with Java, you need to install Java and then continue with setting up Playwright.

Here are the step to instal Java and set up Playwright in Java:

Pro tip: Tools like SUSA can handle this autonomously — upload your app and get results without writing a single test script.

Creating your first Playwright-Java Test

Now that Playwright is set up with Java, you can start writing your first automated trial. The destination here is to see Playwright in action by open a browser, navigating to a web page, and performing introductory checks.

Below is a simple step-by-step example to help you get started:

• Initialize Playwright: Start by make a Playwright instance in a try-with-resources block to ensure proper resource management.
• Launch a Browser: Use the chromium () .launch () method to depart a Chromium browser instance. You can later shift to Firefox or WebKit if want.
• Open a New Page: Create a new page within the browser instance apply browser.newPage (). This page is where all interactions will hap.
• Navigate to a URL: Use the page.navigate (& # 8220; URL & # 8221;) method to go to the website you desire to test.
• Perform Assertions: Use Playwright ’ s assertThat () methods to control page elements, titles, or profile. Playwright automatically waits for weather to be met, reducing the need for manual postponement.
• Interact with Elements: Create locator habituate page.getByRole (), page.locator (), or other locater strategies, and perform actions like click, fill, or hover.
• Close Resources: The try-with-resources structure ensures the browser and Playwright case closely automatically after the test discharge.

Here ’ s a minimum example combining these stairs:

significance com.microsoft.playwright. *; import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; public class FirstTest {public electrostatic void main (String [] args) {try (Playwright playwright = Playwright.create ()) {Browser browser = playwright.chromium () .launch (); Page page = browser.newPage (); page.navigate (`` https: //example.com ''); assertThat (page) .hasTitle (`` Example Domain ''); Locator moreInfo = page.locator (`` text=More information ''); moreInfo.click ();}}}

This basic test demonstrates opening a browser, navigate to a page, ascertain the rubric, and interacting with an element. Once comfortable with this workflow, you can lead it to more complex scenario, multiple pages, and full end-to-end exam.

Integrating Playwright Java with JUnit and TestNG

After create your first Playwright-Java trial, the next step is to incorporate it with democratic Java prove frameworks likeJUnit and TestNG. This integrating allows you to organize tests, run them systematically, and render detailed reports. It also enables seamless performance within CI/CD pipelines.

Below is how Playwright work with these frameworks:

1. JUnit Integration

JUnit provides a structured way to organize and run tests in Java. By integrating Playwright with JUnit, you can separate setup, tryout execution, and cleanup steps so tests are easier to read and maintain.

For example, @ BeforeAll or @ BeforeEach is utilise to start the browser or create pages before tests run. @ AfterEach or @ AfterAll is employ to fold pages and browsers after tests finish. Playwright ’ s assertThat () can so be used privileged test methods to check page titles, elements, or visibility.

Here ’ s how to do it:

importee com.microsoft.playwright. *; importation org.junit.jupiter.api. *; import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; public class JUnitPlaywrightTest {static Playwright playwright; static Browser browser; Page page; @ BeforeAll static vacancy setUp () {playwright = Playwright.create (); browser = playwright.chromium () .launch ();} @ BeforeEach void createPage () {page = browser.newPage ();} @ Test emptiness testExampleTitle () {page.navigate (`` https: //example.com ''); assertThat (page) .hasTitle (`` Example Domain '');} @ AfterEach void closePage () {page.close ();} @ AfterAll static void tearDown () {browser.close (); playwright.close ();}}

2. TestNG Integration

TestNG is similar to JUnit but offers more flexibility with configuration and grouping of tests. Integrating Playwright with TestNG allows you to initialize the browser once per family with @ BeforeClass and pick it up with @ AfterClass.

Case-by-case page can be opened and closed before and after each test method using @ BeforeMethod and @ AfterMethod. This ascertain tests run independently while notwithstanding reusing browser resources, maintain execution fast and consistent.

Here ’ s how to integrate it:

import com.microsoft.playwright. *; import org.testng.annotations. *; import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; public class TestNGPlaywrightTest {Playwright playwright; Browser browser; Page page; @ BeforeClass void setUp () {playwright = Playwright.create (); browser = playwright.chromium () .launch ();} @ BeforeMethod void createPage () {page = browser.newPage ();} @ Test void testExampleTitle () {page.navigate (`` https: //example.com ''); assertThat (page) .hasTitle (`` Example Domain '');} @ AfterMethod void closePage () {page.close ();} @ AfterClass void tearDown () {browser.close (); playwright.close ();}}

Advanced Test Automation Techniques with Playwright and Java

Using Java & # 8217; s object-oriented nature, you can write modular and reclaimable examination book, while Playwright enables you to simulate complex user interactions effortlessly. Together, they enable you to build scalable and maintainable test mechanisation frameworks.

• By effectively care multiple environments with Playwright, you can save valuable time and effort, focusing more on present high-quality software.

3. Parallel Test Execution

When it comes to, Playwright play a crucial role in executing multiple tests simultaneously across different browsers, saving you worthful time and effort. By tackle the parallel test capableness of Playwright, you can run cross-browser tests effortlessly and ensure comprehensive.

4. Handling Auto-Waiting and Mocking APIs for Advanced Automation

Playwright automatically waits for elements to become actionable, which reduces test flakiness when consider with dynamic content. Combined with API mocking, you can simulate server responses, test edge cause, and isolate frontend behavior from backend dependencies. These capabilities aid make extremely reliable tests that handle asynchronous events and complex workflows.

Here ’ s an example that mocks an API response, waits for factor, and validates dynamic content:

import com.microsoft.playwright. *; import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; public class AdvancedTest {public inactive void main (String [] args) {try (Playwright playwright = Playwright.create ()) {Browser browser = playwright.chromium () .launch (); BrowserContext context = browser.newContext (); Page page = context.newPage (); // Mock API response for a specific endpoint page.route (`` https: //api.example.com/data '', route - & gt; {route.fulfill (new Route.FulfillOptions () .setStatus (200) .setContentType (`` application/json '') .setBody (`` {\ '' items\ '': [\ '' A\ '', \ '' B\ '', \ '' C\ '']} ''));}); // Navigate to page and auto-wait ensures constituent are ready page.navigate (`` https: //example.com/dashboard ''); // Auto-wait for constituent to be visible Locator table = page.locator (`` # data-table ''); assertThat (table) .isVisible (); // Perform actions but when elements are ready Locator refreshButton = page.locator (`` button # refresh ''); refreshButton.click (); // Validate that mock data appears in table assertThat (page.locator (`` text=A '')) .isVisible ();}}}

5. Parallelization, Test Isolation, and Running in Headless Mode

Advanced automation requires faster execution and reliable test separation. Playwright supports lam multiple trial simultaneously in isolated browser contexts. Running tests in headless mode reduces resource usage while still maintaining entire browser capabilities, make it idealistic for CI/CD pipelines and large-scale test suites.

Here ’ s an example that escape tests in parallel with isolated contexts and headless browsers:

import com.microsoft.playwright. *; import static com.microsoft.playwright.assertions.PlaywrightAssertions.assertThat; public form ParallelTestExample {public static nothingness main (String [] args) {try (Playwright playwright = Playwright.create ()) {// Launch headless browser for parallel tests Browser browser = playwright.chromium () .launch (new BrowserType.LaunchOptions () .setHeadless (true)); // Create two main circumstance to isolate trial BrowserContext context1 = browser.newContext (); BrowserContext context2 = browser.newContext (); Page page1 = context1.newPage (); Page page2 = context2.newPage (); // Parallel test simulation page1.navigate (`` https: //example.com/login ''); page2.navigate (`` https: //example.com/dashboard ''); assertThat (page1.locator (`` input # username '')) .isVisible (); assertThat (page2.locator (`` # dashboard-content '')) .isVisible (); // Close contexts separately to ensure isolation context1.close (); context2.close (); browser.close ();}}}

Using Playwright for API Testing

While Playwright is primarily known for UI automation, it too proffer powerful capabilities for API testing. You can send HTTP requests instantly, validate responses, and still integrate these cheque into end-to-end workflows. This makes it possible to test backend services, verify endpoints, and unite UI and API validations in a single framework.

Here ’ s an example that mail a GET request, validates the response, and educe data:

import com.microsoft.playwright. *; public stratum ApiTestExample {public static vacancy master (String [] args) {try (Playwright playwright = Playwright.create ()) {APIRequestContext apiRequest = playwright.request () .newContext (); // Send GET request to an API termination APIResponse response = apiRequest.get (`` https: //api.example.com/users/1 ''); // Validate response status if (response.status () == 200) {System.out.println (`` Status is 200 OK '');} // Parse JSON response String body = response.text (); System.out.println (`` Response Body: `` + body); // Extract specific battlefield (exemplar using JSON parse) var json = response.json (); System.out.println (`` User Name: `` + json.get (`` name ''));}}}

Key Points:

• Playwright ’ s APIRequestContext allows sending GET, POST, PUT, DELETE, and other HTTP requests.
• You can corroborate status codes, head, and response bodies immediately within your tests.
• API screen can be combined with UI examination to create full end-to-end workflows, such as formalise that datum submitted via UI appears aright via API.
• Mocking API responses is also potential to simulate backend demeanour without relying on live service.

This approach allow you mingle UI and API automation in Playwright, reducing context switching and enabling faster, more comprehensive examination.

Reporting and Debugging in Playwright Java
