Test Framework Layers

• Driver Layer: Manages browser setup and teardown (e.g., driver_factory.py)
• Page Objects: Classes representing pages with methods to interact with elements and get attributes
• Tests: Test scripts using page objects to verify element attributes and behaviors
• Utilities: Helper functions for common tasks like safely getting element attributes
• Configuration: Environment settings, URLs, credentials stored in YAML files

Configuration Patterns

Use YAML files to store environment URLs, browser types, and credentials.

Example config.yaml:

environments:
  dev:
    url: "https://dev.example.com"
  prod:
    url: "https://www.example.com"
browser: chrome
    

Load config in conftest.py and pass to tests.

Use fixtures to initialize WebDriver with chosen browser and environment URL.

Test Reporting and CI/CD Integration

• Use pytest with pytest-html plugin to generate readable HTML reports showing pass/fail results.
• Include screenshots on failure to help debug attribute-related issues.
• Integrate tests into CI pipelines (GitHub Actions, Jenkins) to run on every code push.
• Fail tests if expected element attributes are missing or incorrect.

Best Practices

1. Use Page Object Model: Encapsulate element locators and attribute getters in page classes.
2. Explicit Waits: Wait for elements to be present before getting attributes to avoid errors.
3. Safe Attribute Access: Use helper methods that return None or default if attribute is missing instead of throwing exceptions.
4. Data-Driven Tests: Test multiple attribute values using parameterized tests.
5. Clear Naming: Name methods like get_element_attribute(name) to clearly show purpose.

Self Check

Where would you add a new method to get the href attribute of a link on the Login page?

Key Result

Organize Selenium Python tests with page objects, utilities for safe attribute access, and config-driven environments.
