+The framework uses a **layered isolation model** combining shared singletons for configuration and reporting with thread-local storage for driver and page object isolation. This enables safe parallel test execution without resource contention.
+
+**Key Components:**
+- **Shared Layer**: ConfigManager (YAML config), ExtentReports (single report file)
+- **Thread-Local Layer**: AppiumDriver, PageObjectManager, ExtentTest instances
+- **Cleanup**: @After hook with try-finally ensures guaranteed resource cleanup

+Each test thread has isolated copies of driver, page objects, and test reporting:
+
+| Component | Isolation Level | Storage | Thread-Safe |

-## Architectural Traceability & Rationale ##
 
-Why This Design?
-Our framework is architected for scalability, maintainability, and parallel execution. Key design choices include:
-
-Layered Traceability:
-Each test scenario flows from .feature files (business intent), through step definitions (glue), into screen/page objects (UI abstraction), and down to base classes and utilities (engine). This clear separation ensures traceability from business requirements to code.
-
-OOP Principles:
-
-Abstract BasePage: Enforces a contract for all screens, sharing common actions while preventing direct instantiation.
-Protected Methods: Restrict low-level actions to subclasses, encapsulating driver logic and reducing accidental misuse.
-Final Utility Classes: (e.g., WdioLocators) Prevent inheritance and instantiation, ensuring a single source of truth for constants and locators.
-Composition Over Inheritance:
-Utility classes (e.g., ElementActions, WaitUtils) are injected into page objects, promoting loose coupling and easier testing.
-
-Thread Safety:
-DriverManager uses ThreadLocal to isolate driver instances, enabling safe parallel test execution and maximizing resource utilization.
-
-Design Patterns:
-
-Singleton: For configuration management, ensuring consistent settings.
-Factory: For driver creation, supporting multiple platforms.
-Page Object Manager: Centralizes and reuses page objects, reducing duplication.
-Architectural Intelligence
-This design:
-
-Supports parallelism (via ThreadLocal drivers).
-Enforces encapsulation (via access modifiers and abstract classes).
-Promotes reusability and maintainability (via composition and design patterns).
-Enables clear traceability from business logic to engine code, making debugging and onboarding easier.
