Test Framework Layers
  • Driver Layer: Manages WebDriver setup and teardown for browser control.
  • Page Objects: Encapsulate page elements and async JavaScript execution methods.
  • Tests: Contains test classes that call async script execution and verify results.
  • Utilities: Helper classes for JavaScript execution, waiting for async scripts to finish.
  • Configuration: Holds environment settings, browser options, and timeouts.
Configuration Patterns
  • Environment Properties: Use TestConfig.java to load environment URLs, timeouts, and browser types from .properties files.
  • Browser Setup: Configure WebDriver with desired capabilities and options for different browsers.
  • Async Script Timeout: Define explicit timeout values for async script execution to avoid indefinite waits.
  • Credentials: Store sensitive data securely outside source code, injected via environment variables or secure vaults.
Test Reporting and CI/CD Integration
  • Use TestNG or JUnit reports to capture pass/fail status of async script execution tests.
  • Integrate with CI/CD pipelines (e.g., Jenkins, GitHub Actions) to run tests automatically on code changes.
  • Generate HTML or XML reports showing detailed results including async script execution times and errors.
  • Use screenshots or logs on failure to help diagnose async script issues.
Best Practices
  • Use explicit waits for async scripts to complete instead of fixed sleeps to improve test reliability.
  • Encapsulate async JavaScript execution in utility methods to reuse and simplify test code.
  • Keep page objects focused on UI elements and delegate async script logic to utilities.
  • Handle JavaScript errors gracefully and fail tests with clear messages if async scripts do not complete.
  • Parameterize async script timeouts to adapt to different environments and network conditions.
Self Check

Where in this folder structure would you add a new utility method to wait for a custom async JavaScript event?

Key Result
Organize async script execution by separating page objects, utilities for JS execution, and configuration for timeouts.
