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+.
Supporting reference files are available for deeper topics:
| Topic | File |
|---|---|
| Maven POM, ConfigReader, Docker/CI setup | references/config.md |
| Component pattern, dropdowns, uploads, waits | references/page-objects.md |
| Full assertion API, soft assertions, visual testing | references/assertions.md |
| Fixtures, test data factory, auth state, retry | references/fixtures.md |
| Drop-in base class templates | templates/BaseTest.java, templates/BasePage.java |
Thread.sleep() with proper waitsUse this matrix to pick the right pattern before writing any code:
| User Request | Approach |
|---|---|
| New project from scratch | Full scaffold — see references/config.md |
| Single feature test | POM page class + JUnit5 test class |
| API + UI hybrid | APIRequestContext alongside Page |
| Cross-browser | @MethodSource parameterized over browser names |
| Flaky test fix | Replace sleep with waitFor / waitForResponse |
| CI integration | playwright install --with-deps in pipeline |
| Parallel execution | junit-platform.properties + ThreadLocal |
| Rich reporting | Allure + Playwright trace + video recording |

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.
