Master Selenium: The Only Tutorial You’ll Ever Need

In the world of web development and software testing, automation has become a necessity. If you’re tired of manually testing every button, form, and function on a website, then it’s time to embrace the power of automation. In this Selenium Tutorial by Tpoint Tech, you’ll learn everything you need to know to get started with Selenium, the most powerful and flexible tool for browser automation.

Whether you're a beginner or an aspiring QA engineer, this guide will help you master Selenium and use it like a pro.

🔍 What is Selenium?

Before we dive into the hands-on part, let’s first understand what Selenium is.

Selenium is an open-source automation tool primarily used for testing web applications. It lets you programmatically control web browsers to simulate human actions like clicking buttons, entering text, submitting forms, and navigating pages.

🔑 Key Features:

• Supports all major browsers: Chrome, Firefox, Edge, Safari

• Works on multiple platforms: Windows, macOS, Linux

• Supports multiple programming languages: Python, Java, C#, JavaScript, Ruby

• Ideal for both testing and web scraping

⚙️ Why Use Selenium with Python?

While Selenium supports several languages, Python is one of the most popular choices due to its simplicity and readability. Combining Selenium with Python makes it easy to write powerful automation scripts quickly.

🧰 Getting Started – Setup Guide

Step 1: Install Python

If you don’t have Python installed yet, download it from python.org. Be sure to check “Add Python to PATH” during installation.

Step 2: Install Selenium

Open your terminal or command prompt and run:

pip install selenium

Step 3: Download WebDriver

Selenium needs a WebDriver to communicate with your browser. If you're using Chrome, download ChromeDriver.

Make sure the ChromeDriver version matches your Chrome browser version.

💻 Your First Selenium Script

Let’s write a simple script that opens Google, searches for “Tpoint Tech,” and prints the titles of the search results.

✅ Example Code

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
import time

# Launch Chrome
driver = webdriver.Chrome()

# Open Google
driver.get("https://www.google.com")

# Search for Tpoint Tech
search_box = driver.find_element(By.NAME, "q")
search_box.send_keys("Tpoint Tech")
search_box.send_keys(Keys.RETURN)

# Wait for results
time.sleep(2)

# Print titles
results = driver.find_elements(By.TAG_NAME, "h3")
for result in results:
    print(result.text)

# Close browser
driver.quit()

🎉 Congratulations! You’ve just automated your first browser task.

🔐 Automate a Login Form

Let’s take it up a notch and automate a login process.

✅ Login Automation Example

from selenium import webdriver
from selenium.webdriver.common.by import By
import time

driver = webdriver.Chrome()
driver.get("https://example.com/login")

# Fill in login form
driver.find_element(By.ID, "username").send_keys("myuser")
driver.find_element(By.ID, "password").send_keys("mypassword")

# Submit form
driver.find_element(By.ID, "login-button").click()

# Wait and close
time.sleep(3)
driver.quit()

Make sure to replace the URLs and element IDs with actual values from the website you're testing.

🧠 Pro Tip: Use Explicit Waits

Avoid hardcoded time.sleep() whenever possible. Use WebDriverWait to wait until elements are ready.

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# Wait up to 10 seconds for an element
WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, "dashboard"))
)

🤖 Headless Mode (No Browser Window)

Want to run your scripts in the background without opening a browser window? Use headless mode:

from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("--headless")

driver = webdriver.Chrome(options=options)
driver.get("https://tpoint.tech")
print(driver.title)
driver.quit()

💡 Best Practices from Tpoint Tech

• ✅ Use try-except blocks to handle exceptions

• ✅ Always close the browser with driver.quit()

• ✅ Use Page Object Model (POM) for larger projects

• ✅ Group tests using frameworks like pytest or unittest
