Test Framework Layers

• Driver Layer: Manages browser setup and teardown using Selenium WebDriver.
• Page Objects: Classes representing pages, with methods to find elements by class name and interact with them.
• Tests: Test functions or classes that use page objects to perform actions and assertions.
• Utilities: Helper functions for common tasks like waits or logging.
• Configuration: Central place for environment variables, browser options, and credentials.

Configuration Patterns

Use a config.py file to store settings like:

• Base URL of the application
• Browser choice (e.g., Chrome, Firefox)
• Timeouts for waits
• Credentials (use environment variables or secure vaults for sensitive data)

Example snippet from config.py:

import os

BASE_URL = "https://example.com"
BROWSER = "chrome"
IMPLICIT_WAIT = 10
USERNAME = os.getenv("APP_USERNAME")
PASSWORD = os.getenv("APP_PASSWORD")

Test Reporting and CI/CD Integration

• Use pytest with plugins like pytest-html for readable HTML reports.
• Integrate tests in CI/CD pipelines (GitHub Actions, Jenkins) to run on each code push.
• Configure reports to show pass/fail status and screenshots on failure.
• Use logs to help debug element finding issues, especially with class name selectors.

Best Practices

• Use Page Object Model to separate element locators and test logic.
• Prefer explicit waits over implicit waits to wait for elements by class name.
• Use descriptive class names in locators to avoid brittle tests.
• Handle cases where multiple elements share the same class by using find_elements and indexing.
• Keep locators in one place (page objects) to ease maintenance.

Self Check

Where in this folder structure would you add a new method to find an element by class name on the Login page?

Key Result

Organize Selenium Python tests using Page Objects with class name locators, explicit waits, and clear config for maintainability.
