Selenium Python Framework Architecture

Modern Framework Foundation

• pytest Framework: Leverage pytest's powerful fixture system and plugin ecosystem
• Modular Architecture: Separate concerns with clear package structure
• Configuration Management: Environment-specific settings with proper inheritance
• Dependency Management: Pinned versions with regular security updates

pytest Configuration Excellence

# conftest.py - Global configuration
import pytest
import os
from selenium import webdriver
from selenium.webdriver.chrome.options import Options as ChromeOptions
from webdriver_manager.chrome import ChromeDriverManager

def pytest_addoption(parser):
    """Command line options for flexible test execution."""
    parser.addoption("--browser", action="store", default="chrome")
    parser.addoption("--headless", action="store_true", default=False)
    parser.addoption("--env", action="store", default="dev")
    parser.addoption("--parallel", action="store", default="1")

@pytest.fixture(scope="session")
def browser_config(request):
    """Browser configuration based on command line arguments."""
    return {
        "browser": request.config.getoption("--browser"),
        "headless": request.config.getoption("--headless"),
        "environment": request.config.getoption("--env")
    }
