Selenium Testing Tutorials with Examples: A Complete Beginner Guide

November 20, 2025

Selenium is one of the most widely used automation testing tools for web applications. Its ability to automate browsers, support multiple programming languages, and integrate with popular frameworks makes it a top choice for QA professionals. Whether you're a beginner or looking to upgrade your QA skills, this guide will walk you through Selenium basics, key components, and practical examples to help you get started with automation testing.

What Is Selenium?

Selenium is an open-source automation testing tool used to test web applications across different browsers like Chrome, Firefox, Safari, and Edge. It supports multiple programming languages including Java, Python, JavaScript, C#, and Ruby.

Selenium has four key components:

Selenium WebDriver
Selenium IDE
Selenium Grid
Selenium RC (deprecated)

Among these, Selenium WebDriver is the most popular and widely used for modern automation needs.

Why Use Selenium for Automation?

Supports multiple browsers
Cross-platform compatibility
Integrates with tools like TestNG, JUnit, Maven, Jenkins, GitHub Actions
Fast execution & reusable scripts
Huge community support

Selenium makes automation faster, more accurate, and scalable compared to manual testing.

Getting Started with Selenium WebDriver

For beginners, Java is the most commonly used language, but Python and JavaScript are also excellent options.

Here’s the basic setup for Selenium WebDriver:

1. Install Java or Python

Choose your preferred language environment.

2. Install Eclipse, IntelliJ, or VS Code

IDE for writing automation scripts.

3. Download Selenium WebDriver

Available from Selenium’s official website.

4. Add Browser Drivers

Example:

ChromeDriver
GeckoDriver (Firefox)
EdgeDriver

Selenium Example 2: Automate Search Action (Python)

from selenium import webdriver

from selenium.webdriver.common.by import By

from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome()

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

search = driver.find_element(By.NAME, "q")

search.send_keys("Selenium automation tutorial")

search.send_keys(Keys.RETURN)

driver.quit()

What this example shows:

Opening a browser
Locating an input field
Typing a keyword
Performing a search

Selenium Example 3: Button Click & Validation (JavaScript)

const { Builder, By } = require('selenium-webdriver');

(async function example() {

let driver = await new Builder().forBrowser('chrome').build();

await driver.get('https://example.com');

const button = await driver.findElement(By.id('submit'));

await button.click();

const message = await driver.findElement(By.id('success'));

console.log(await message.getText());

await driver.quit();

})();

This script clicks a button and checks if a success message appears.

Final Thoughts

Selenium remains a powerful tool for web automation, offering flexibility, speed, and strong community support. By learning WebDriver basics and practicing with simple examples like opening a webpage, performing searches, clicking buttons, and validating outputs, beginners can quickly build a strong foundation in automation testing.

As you progress, you can integrate Selenium with frameworks like TestNG, PyTest, JUnit, or Cucumber, and expand into CI/CD automation using Jenkins, GitHub Actions, or Docker.
