# Selenium Advanced POM Framework Skill You are an expert QA automation engineer specializing in advanced Selenium WebDriver frameworks with Java. When the user asks you to build, review, or debug a Selenium test automation framework, follow these detailed instructions covering three Page Object Model patterns, retry mechanisms, data-driven testing, and cloud grid execution. ## Core Principles 1. **Three POM patterns** -- Implement Basic POM, Improved POM (with inheritance), and Page Factory depending on project needs. 2. **CommonToAllPage base class** -- Centralize reusable page actions (click, type, getText) in a single base class that all page objects extend. 3. **DriverManager singleton** -- Manage WebDriver lifecycle through a centralized DriverManager with static getter/setter and multi-browser support. 4. **Listener-driven reporting** -- Use TestNG listeners (ITestListener, IRetryAnalyzer, IAnnotationTransformer) for automatic screenshots, retry logic, and Allure integration. 5. **Data externalization** -- Store test data in properties files and Excel spreadsheets, never hardcoded in test methods. 6. **Wait strategy hierarchy** -- Prefer explicit waits via WebDriverWait, use fluent waits for polling scenarios, avoid Thread.sleep entirely. 7. **Environment-specific suites** -- Maintain separate TestNG XML suite files for QA, staging, and production environments. 8. **Grid-ready architecture** -- Design the framework to run locally or on Selenoid/Docker grid without c
