🧪 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
