Test Framework Layers
  • Driver Layer: driver_factory.py creates and manages WebDriver instances with browser options.
  • Page Objects: Classes in pages/ represent pages and frames. For nested iFrames, iframe_page.py handles switching between frames.
  • Tests: Test scripts in tests/ use page objects to perform actions and assertions on nested iFrames.
  • Utilities: Helper functions like explicit waits in wait_utils.py to handle dynamic loading inside iFrames.
  • Configuration: config.yaml stores environment URLs, browser types, and credentials.
Configuration Patterns

Use a config.yaml file to store settings:

environment:
  url: "https://example.com/nested_iframes"
browser: "chrome"
implicit_wait: 10
explicit_wait: 15

Load config in driver_factory.py to create WebDriver with chosen browser and wait times.

Use environment variables or command-line options to switch environments or browsers without code changes.

Test Reporting and CI/CD Integration
  • Use pytest with pytest-html plugin to generate readable HTML reports after test runs.
  • Integrate tests in CI/CD pipelines (GitHub Actions, Jenkins) to run on every code push or pull request.
  • Configure test retries and screenshots on failure to help diagnose nested iFrame issues.
  • Reports show pass/fail status of tests interacting with nested iFrames clearly.
Best Practices for Nested iFrames Testing Framework
  1. Use Page Object Model: Create separate page objects for main page and each iFrame to keep code clean and reusable.
  2. Explicit Waits: Always use explicit waits when switching to iFrames to ensure elements inside are loaded.
  3. Clear Frame Switching: Always switch back to default content after working inside an iFrame to avoid stale context errors.
  4. Isolate Tests: Each test should start with a fresh driver state and navigate to the main page to avoid dependencies.
  5. Configurable Settings: Use config files and environment variables to easily change browsers and URLs without code edits.
Self Check

Where in this folder structure would you add a new page object for a third nested iFrame inside the existing iFrame?

Key Result
Organize nested iFrame tests with clear page objects, explicit waits, and config-driven WebDriver setup.
