Are you still spending hours manually clicking through your web app just to test a few features? 😫

It’s time to upgrade your workflow and sanity with Selenium — the powerful open-source tool that’s revolutionizing how developers approach UI testing.

In this post, I’ll walk you through exactly how to get started with Selenium, write your first test, and unlock a level of automation that’ll save you hours of tedious testing.

Whether you're building a React app, a static site, or anything in between — this guide will help you get more done with less.

🧠 Why Selenium Is Still the King of UI Automation

Selenium has been around for a while, and there’s a reason it hasn’t faded — it works.

And it works with all major browsers, across multiple programming languages (Python, JavaScript, Java, etc.).

Some powerful use cases include:

  • Automating form submissions
  • Testing login/logout workflows
  • Validating error messages and alert modals
  • Screenshotting UI regressions
  • Testing across multiple browsers

And the best part? You can integrate it with CI/CD tools for full automation.

🚀 Setting Up Selenium with Python (Quickstart)

To show you the fastest way forward, we’ll use Python for this example — it’s beginner-friendly, and Selenium support is solid.

✅ Step 1: Install Selenium 

pip install selenium

Also, install the WebDriver for your preferred browser. For Chrome:

✅ Step 2: Write Your First UI Test

Here’s a basic script that opens Google, searches for "Dev.to", and prints the page title:

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

driver = webdriver.Chrome()  # or Firefox()
driver.get("https://www.google.com")

search_box = driver.find_element(By.NAME, "q")
search_box.send_keys("Dev.to")
search_box.send_keys(Keys.RETURN)

print(driver.title)
driver.quit()

👀 That’s it. You just automated a real browser interaction!

🎯 Pro Tips to Make Your Selenium Scripts More Powerful

If you really want to level up, try these:

  • Use WebDriverWait to handle dynamic loading elements 
from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC

  WebDriverWait(driver, 10).until(
      EC.presence_of_element_located((By.ID, "main"))
  )
  • Run headless mode (for faster tests without opening the browser window) 
from selenium.webdriver.chrome.options import Options

  options = Options()
  options.add_argument("--headless")
  driver = webdriver.Chrome(options=options)
  • Use tools like SeleniumBase for enhanced reporting and features

  • Add screenshots automatically on test failure 
driver.save_screenshot('error.png')

🛠 Tools and Resources You Should Know

– Clean and scalable test structure

🙌 Ready to Automate Your First App?

Imagine this: instead of manually checking if your login page still works after every push, you run a script and it tells you instantly what broke. That’s the peace of mind automation offers.

Once you get the basics down, start integrating Selenium into your:

  • CI/CD pipeline (GitHub Actions, GitLab, Jenkins)
  • Regression testing suites
  • Cross-browser compatibility tests

You’ll quickly realize how much time and energy you save in the long run.

👉 If you’ve tried Selenium before, what’s your biggest win or worst headache?
