Playwright Java – Advanced Test Automation

Overview

This public intake copy packages

plugins/antigravity-awesome-skills-claude/skills/playwright-java

https://github.com/sickn33/antigravity-awesome-skills

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses

metadata.json

ORIGIN.md

Playwright Java – Advanced Test Automation

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: How It Works, Common Pitfalls, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• Use when scaffolding a new Playwright Java project from scratch
• Use when writing Page Object classes or JUnit 5 test classes
• Use when the user asks about cross-browser testing, parallel execution, or Allure reports
• Use when fixing flaky tests or replacing Thread.sleep() with proper waits
• Use when setting up Playwright in CI/CD pipelines (GitHub Actions, Jenkins, Docker)
• Use when combining API calls and UI assertions in a single test (hybrid testing)

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

1. Confirm the user goal, the scope of the imported workflow, and whether this skill is still the right router for the task.
2. Read the overview and provenance files before loading any copied upstream support files.
3. Load only the references, examples, prompts, or scripts that materially change the outcome for the current request.
4. Execute the upstream workflow while keeping provenance and source boundaries explicit in the working notes.
5. Validate the result against the upstream expectations and the evidence you can point to in the copied files.
6. Escalate or hand off to a related skill when the work moves out of this imported workflow's center of gravity.
7. Before merge or closure, record what was used, what changed, and what the reviewer still needs to verify.

Imported Workflow Notes

Imported: Overview

This skill produces production-quality, enterprise-grade Playwright Java test code. It enforces the Page Object Model (POM), strict locator strategies, thread-safe parallel execution, and full Allure reporting integration. Targets Java 17+ and Playwright 1.44+.

Step 2: Scaffold the Project Structure

Always use this layout when creating a new project:

├── test/
│   ├── java/com/company/tests/
│   │   ├── base/
│   │   │   ├── BaseTest.java        ← templates/BaseTest.java

pom.xml

Step 3: Set Up Thread-Safe BaseTest

public class BaseTest {
    protected static ThreadLocal<Playwright>     playwrightTL = new ThreadLocal<>();
    protected static ThreadLocal<Browser>        browserTL    = new ThreadLocal<>();
    protected static ThreadLocal<BrowserContext> contextTL    = new ThreadLocal<>();
    protected static ThreadLocal<Page>           pageTL       = new ThreadLocal<>();

    protected Page page() { return pageTL.get(); }

    @BeforeEach
    void setUp() {
        Playwright playwright = Playwright.create();
        playwrightTL.set(playwright);

        Browser browser = resolveBrowser(playwright).launch(
            new BrowserType.LaunchOptions()
                .setHeadless(ConfigReader.isHeadless()));
        browserTL.set(browser);

        BrowserContext context = browser.newContext(new Browser.NewContextOptions()
            .setViewportSize(1920, 1080)
            .setRecordVideoDir(Paths.get("target/videos/"))
            .setLocale("en-US"));
        context.tracing().start(new Tracing.StartOptions()
            .setScreenshots(true).setSnapshots(true));
        contextTL.set(context);
        pageTL.set(context.newPage());
    }

    @AfterEach
    void tearDown(TestInfo testInfo) {
        String name = testInfo.getDisplayName().replaceAll("[^a-zA-Z0-9]", "_");
        contextTL.get().tracing().stop(new Tracing.StopOptions()
            .setPath(Paths.get("target/traces/" + name + ".zip")));
        pageTL.get().close();
        contextTL.get().close();
        browserTL.get().close();
        playwrightTL.get().close();
    }

    private BrowserType resolveBrowser(Playwright pw) {
        return switch (System.getProperty("browser", "chromium").toLowerCase()) {
            case "firefox" -> pw.firefox();
            case "webkit"  -> pw.webkit();
            default        -> pw.chromium();
        };
    }
}

Step 4: Build Page Object Classes

public class LoginPage extends BasePage {

    // Declare ALL locators as fields — never inline in action methods
    private final Locator emailInput;
    private final Locator passwordInput;
    private final Locator loginButton;
    private final Locator errorMessage;

    public LoginPage(Page page) {
        super(page);
        emailInput    = page.getByLabel("Email address");
        passwordInput = page.getByLabel("Password");
        loginButton   = page.getByRole(AriaRole.BUTTON,
                            new Page.GetByRoleOptions().setName("Sign in"));
        errorMessage  = page.getByTestId("login-error");
    }

    @Override protected String getUrl() { return "/login"; }

    // Navigation methods return the next Page Object — enables fluent chaining
    public DashboardPage loginAs(String email, String password) {
        fill(emailInput, email);
        fill(passwordInput, password);
        clickAndWaitForNav(loginButton);
        return new DashboardPage(page);
    }

    public LoginPage loginExpectingError(String email, String password) {
        fill(emailInput, email);
        fill(passwordInput, password);
        loginButton.click();
        errorMessage.waitFor();
        return this;
    }

    public String getErrorMessage() { return errorMessage.textContent(); }
}

Step 5: Write Tests with Allure Annotations

@ExtendWith(AllureJunit5.class)
class LoginTest extends BaseTest {

    private LoginPage loginPage;

    @BeforeEach
    void openLoginPage() {
        loginPage = new LoginPage(page());
        loginPage.navigate();
    }

    @Test
    @Severity(SeverityLevel.BLOCKER)
    @DisplayName("Valid credentials redirect to dashboard")
    void shouldLoginWithValidCredentials() {
        User user = TestDataFactory.getDefaultUser();
        DashboardPage dash = loginPage.loginAs(user.email(), user.password());

        assertThat(page()).hasURL(Pattern.compile(".*/dashboard"));
        assertThat(dash.getWelcomeBanner()).containsText("Welcome, " + user.firstName());
    }

    @Test
    void shouldShowErrorOnInvalidCredentials() {
        loginPage.loginExpectingError("bad@test.com", "wrongpass");

        SoftAssertions softly = new SoftAssertions();
        softly.assertThat(loginPage.getErrorMessage()).contains("Invalid email or password");
        softly.assertThat(page()).hasURL(Pattern.compile(".*/login"));
        softly.assertAll();
    }

    @ParameterizedTest
    @MethodSource("provideInvalidCredentials")
    void shouldRejectInvalidCredentials(String email, String password, String expectedError) {
        loginPage.loginExpectingError(email, password);
        assertThat(loginPage.getErrorMessage()).containsText(expectedError);
    }

    static Stream<Arguments> provideInvalidCredentials() {
        return Stream.of(
            Arguments.of("", "password123", "Email is required"),
            Arguments.of("user@test.com", "", "Password is required"),
            Arguments.of("notanemail", "pass", "Invalid email format")
        );
    }
}

Examples

Example 1: Ask for the upstream workflow directly

Use @playwright-java to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @playwright-java against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @playwright-java for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @playwright-java using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Imported Usage Notes

Imported: Examples

Example 1: API + UI Hybrid Test

@Test
void shouldDisplayNewlyCreatedOrder() {
    // Arrange via API — faster than navigating through UI
    APIRequestContext api = page().context().request();
    APIResponse response = api.post("/api/orders",
        RequestOptions.create()
            .setHeader("Authorization", "Bearer " + authToken)
            .setData(Map.of("productId", "SKU-001", "quantity", 2)));
    assertThat(response).isOK();

    String orderId = new JsonParser().parse(response.text())
        .getAsJsonObject().get("id").getAsString();

    OrdersPage orders = new OrdersPage(page());
    orders.navigate();
    assertThat(orders.getOrderRowById(orderId)).isVisible();
}

Example 2: Network Mocking

@Test
void shouldHandleApiFailureGracefully() {
    page().route("**/api/products", route -> route.fulfill(
        new Route.FulfillOptions()
            .setStatus(503)
            .setBody("{\"error\":\"Service Unavailable\"}")
            .setContentType("application/json")));

    ProductsPage products = new ProductsPage(page());
    products.navigate();

    assertThat(products.getErrorBanner())
        .hasText("We're having trouble loading products. Please try again.");
}

Example 3: Parallel Cross-Browser Test

@ParameterizedTest
@MethodSource("browsers")
void shouldRenderCheckoutOnAllBrowsers(String browserName) {
    System.setProperty("browser", browserName);
    new CheckoutPage(page()).navigate();
    assertThat(page().locator(".checkout-form")).isVisible();
}

static Stream<String> browsers() {
    return Stream.of("chromium", "firefox", "webkit");
}

Example 4: Parallel Execution Config

# src/test/resources/junit-platform.properties
junit.jupiter.execution.parallel.enabled=true
junit.jupiter.execution.parallel.mode.default=concurrent
junit.jupiter.execution.parallel.config.strategy=fixed
junit.jupiter.execution.parallel.config.fixed.parallelism=4

Example 5: GitHub Actions CI Pipeline

- name: Install Playwright browsers
  run: mvn exec:java -e -Dexec.mainClass=com.microsoft.playwright.CLI -Dexec.args="install --with-deps"

- name: Run tests
  run: mvn test -Dbrowser=${{ matrix.browser }} -Dheadless=true

- name: Upload traces on failure
  uses: actions/upload-artifact@v4
  if: failure()
  with:
    name: playwright-traces
    path: target/traces/

- name: Upload Allure results
  uses: actions/upload-artifact@v4
  if: always()
  with:
    name: allure-results
    path: target/allure-results/

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• ✅ Use ThreadLocal<Page> for every parallel-safe test suite
• ✅ Declare all Locator fields at the top of the Page Object class
• ✅ Return the next Page Object from navigation methods (fluent chaining)
• ✅ Use assertThat(locator) — it auto-retries until timeout
• ✅ Use getByRole, getByLabel, getByTestId as first-choice locators
• ✅ Start tracing in @BeforeEach and stop with a file path in @AfterEach
• ✅ Use SoftAssertions when validating multiple fields on a single page

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in

plugins/antigravity-awesome-skills-claude/skills/playwright-java

metadata.json

ORIGIN.md

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated

SKILL.md

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Reference Notes

Imported: Common Pitfalls

• Problem: Tests fail randomly in parallel mode Solution: Ensure every test creates its own

  Playwright → Browser → BrowserContext → Page

  chain via

  ThreadLocal

  . Never share a

  Page

  across threads.

• Problem:

  assertThat(locator).isVisible()

  times out even when the element appears Solution: Increase timeout with

  .setTimeout(10_000)

  or raise

  context.setDefaultTimeout()

  in

  BaseTest

  .

• Problem:

  Thread.sleep(2000)

  was added but tests are still flaky Solution: Replace with

  page.waitForResponse("**/api/endpoint", () -> action())

  or

  assertThat(locator).hasText("Done")

  which polls automatically.

• Problem: Playwright trace zip is empty or missing Solution: Ensure

  tracing().start()

  is called before test actions and

  tracing().stop()

  is in

  @AfterEach

  — not

  @AfterAll

  .

• Problem: Allure report is blank or missing steps Solution: Add the AspectJ agent to

  maven-surefire-plugin

  <argLine>

  in

  pom.xml

  — see

  references/config.md

  for the exact snippet.

• Problem:

  storageState

  auth file is stale and tests redirect to login Solution: Re-run

  AuthSetup

  to regenerate

  target/auth/user-state.json

  before the suite, or add a

  @BeforeAll

  that conditionally refreshes it.

Imported: Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
