Test Framework Layers

• Driver Layer: utils/driver_factory.py manages browser setup and teardown.
• Page Objects: pages/ contains classes representing web pages, each with methods to find elements by ID and interact with them.
• Tests: tests/ holds test scripts that use page objects to perform actions and assertions.
• Utilities: utils/config.py stores configuration like URLs and credentials.
• Fixtures: conftest.py defines setup and teardown hooks for tests.

Configuration Patterns

Use utils/config.py to store environment variables such as base URLs and credentials. Use conftest.py to read these configurations and pass them to tests and driver setup.

Example: config.py holds a dictionary with environment details. driver_factory.py reads browser choice from environment variables or config file to launch the correct browser.

Test Reporting and CI/CD Integration

• Use pytest with pytest-html plugin to generate HTML reports saved in reports/.
• Integrate tests in CI/CD pipelines (e.g., GitHub Actions, Jenkins) to run tests on code push and publish reports.
• Use clear test names and assertions to make reports easy to understand.

Best Practices

1. Use Page Object Model: Encapsulate element locators and actions in page classes to keep tests clean.
2. Locate Elements by ID: IDs are unique and fast to find, so prefer find_element(By.ID, "element_id") when possible.
3. Explicit Waits: Use explicit waits to wait for elements by ID to be present before interacting.
4. Keep Locators Centralized: Store element IDs as constants or variables in page objects for easy maintenance.
5. Readable Test Names: Name tests clearly to reflect what element by ID is being tested.

Self Check

Where in this folder structure would you add a new page object class for a page that contains an element you want to find by ID?

Key Result

Use Page Object Model with unique element IDs and explicit waits for reliable Selenium Python tests.
