Selenium with Pytest: Writing and Running Tests
🧪 Selenium with Pytest: Writing and Running Tests
🚀 What Is Selenium?
Selenium is a tool for automating web browsers — great for testing web apps by simulating real user interactions.
🔍 What Is Pytest?
Pytest is a powerful testing framework for Python. It’s clean, readable, and supports fixtures, assertions, and plugins.
🧰 What You Need to Get Started
✅ Install Required Packages
bash
Copy
Edit
pip install selenium pytest
Also install a web driver like ChromeDriver or GeckoDriver (for Firefox).
📝 Example: Basic Selenium Test with Pytest
Step 1: Create a Test File — test_google_search.py
python
Copy
Edit
from selenium import webdriver
from selenium.webdriver.common.by import By
import pytest
import time
@pytest.fixture
def browser():
# Setup: Start the browser
driver = webdriver.Chrome()
yield driver
# Teardown: Close the browser
driver.quit()
def test_google_search(browser):
browser.get("https://www.google.com")
search_box = browser.find_element(By.NAME, "q")
search_box.send_keys("Selenium with Pytest")
search_box.submit()
time.sleep(2) # Wait for results to load (not ideal for real tests)
assert "Selenium with Pytest" in browser.title
🏃 How to Run the Test
From the terminal:
bash
Copy
Edit
pytest test_google_search.py
Pytest will automatically:
Find the test
Launch the browser
Run the test
Show you the results
🔄 Better Testing: Use Explicit Waits Instead of sleep
python
Copy
Edit
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
def test_google_search(browser):
browser.get("https://www.google.com")
search_box = browser.find_element(By.NAME, "q")
search_box.send_keys("Selenium with Pytest")
search_box.submit()
WebDriverWait(browser, 10).until(
EC.title_contains("Selenium with Pytest")
)
assert "Selenium with Pytest" in browser.title
⚙️ Organizing Tests
Place all tests inside a folder like tests/
Use conftest.py for shared fixtures (e.g., browser setup)
Use --html=report.html for an HTML report (with pytest-html plugin)
🧠 Useful Pytest Commands
Command Description
pytest Run all tests
pytest -v Verbose mode
pytest -k "search" Run tests matching keyword
pytest --maxfail=1 Stop after first failure
pytest --html=report.html Generate test report (plugin needed)
📦 Optional: Use pytest-selenium Plugin
Install:
bash
Copy
Edit
pip install pytest-selenium
It simplifies browser setup and allows command-line browser selection:
bash
Copy
Edit
pytest --driver Chrome
✅ Summary
Selenium handles browser automation
Pytest manages test execution and reporting
Together, they make writing UI tests simple, structured, and scalable
