Test Framework Layers

• Driver Layer: Manages browser setup and teardown (e.g., driver_manager.py).
• Page Objects: Encapsulate page elements and actions, including iframe handling (iframe_page.py).
• Tests: Test scripts that use page objects to perform actions and assertions (test_iframe_switching.py).
• Utilities: Helper functions for waits, logging, or common actions.
• Configuration: Environment settings, browser options, and credentials (config.yaml).

Configuration Patterns

Use a config.yaml file to store environment URLs, browser types, and credentials. Load this config in driver_manager.py to initialize the WebDriver accordingly.

Example config.yaml snippet:

url: "https://example.com/iframe"
browser: "chrome"
implicit_wait: 10
  

This allows easy switching between environments and browsers without changing test code.

Test Reporting and CI/CD Integration

• Use pytest with pytest-html plugin to generate readable HTML reports in the reports/ folder.
• Integrate tests into CI/CD pipelines (e.g., GitHub Actions, Jenkins) to run tests automatically on code changes.
• Reports include pass/fail status, screenshots on failure, and logs for iframe switching steps.

Framework Design Principles

• Use Page Object Model: Encapsulate iframe switching inside page objects to keep tests clean.
• Explicit Waits: Wait for iframe to be available before switching to avoid flaky tests.
• Clear Switching Back: Always switch back to the default content after iframe interactions.
• Configurable Browser Setup: Use config files to manage browser and environment settings.
• Reusable Driver Management: Centralize WebDriver setup and teardown for consistency.

Self Check

Where in this folder structure would you add a new page object for a page that contains multiple iframes?

Key Result

Organize Selenium Python tests with clear layers: driver management, page objects handling iframe switching, tests, utilities, and config for flexible, maintainable automation.
