Playwright with Java – From Basics to Advanced Testing

Set up your Java project on macOS by installing homebrew, OpenJDK 18, Maven, Git, and IntelliJ community edition, then prepare to download the starter GitHub repo in the next lesson.

Set up a Windows development environment for this course by installing OpenJDK 19, Maven, Git, and the IntelliJ Community Edition using Chocolatey, ensuring Java and mvn are on the path.

Set up a Java Maven project, add JUnit and Playwright dependencies, and write your first Playwright test in Java, launching Chromium and navigating to google.com.

Discover how auto waiting in Playwright increases test reliability by awaiting states such as attached, visible, stable, enabled, and editable before actions, and per-action fluent timeouts.

Explore playwright browsers, browser context, and pages by launching chromium, firefox, or webkit and creating pages within isolated contexts. utilize multiple contexts for parallel sessions and multiple users.

Learn how selectors and locators identify page elements in Playwright, using XPath, CSS, text, and data attributes to perform actions like click, with a BestBuy test and browser geolocation permissions.

Learn to use Playwright locators by storing element definitions, handling strictness for single matches, and filtering with has text to click items like deal of the day, with page synchronization.

Master click, fill, and check actions in Playwright by simulating a sign-up flow on the Best Buy site, using CSS selectors and locators to fill the account form.

Explore Playwright assertions that automatically wait and retry until a condition is met, with a default five-second timeout and configurable options for text, enablement, and signup form validation.

Refactor your Playwright with Java tests by extracting common setup into a Playwright runner class and extending tests to reuse the browser, context, and page, with before-each lifecycle.

Implement a page object model in a Playwright for Java project to centralize page locators and actions, reducing duplication on create account pages.

Build a generic account navigation in a page object model to reach create account or sign in via a display-name enum and template-based locators. Centralizes selectors and reduces test code.

Learn how to initialize pages in a Java Playwright runner using a custom annotation and reflection to auto-create page objects, avoiding manual constructor calls for each new page.

Read environment-specific properties from property files and switch test URLs by using an environment reader service and a system property to select production or staging.

Build a sign-in test in a Java Playwright framework by adding a sign-in page object, reading email and password from a property file, and validating sign-in on the home page.

Learn to manage timeouts in Playwright for Java by increasing default timeouts on browser context or page and by using per-action options, with awareness of precedence and assertion limits.

Discover debugging with the Playwright inspector, a GUI that reveals selectors and records tests. Configure environment variables in IntelliJ to start it automatically or on demand.

Learn to debug selectors by exposing the Playwright object to DevTools, using console and breakpoints to inspect elements, copy selectors, and test clicks directly in browser DevTools.

Use playwright's trace viewer to debug tests by recording actions into a trace zip, with start/stop tracing, screenshots, snapshots, and sources, then inspect actions and network calls in the GUI.

Enable video recording for Playwright tests by setting the record video directory and optional full HD size to save videos in a folder.

Learn to use a JUnit 5 test watcher to store Playwright traces and videos only on test failures, with custom naming and cleanup logic.

Explore parallel execution with JUnit 5 and the Maven Surefire plugin, running tests by class while handling Playwright not thread-safe with per-class lifecycle and a dynamic strategy (factor 0.5).

Configure Selenium Grid to run tests in parallel with a hub and multiple nodes, coordinating executions across browsers like Chrome and Safari via the remote hub URL.
