Summary:
This guide introduces Automation Testing with Selenium, the most popular open-source tool for automating web applications. Whether you’re a manual tester transitioning to automation or a developer adding test automation to your workflow, this blog helps you learn Selenium from setup to execution. It includes interview questions and highlights the Uplatz training program for mastering Selenium automation.
Introduction:
Selenium has become the gold standard for browser-based automation testing. Its flexibility, compatibility with multiple languages, and open-source nature make it a favourite among QA engineers and developers. Selenium supports functional and regression testing, integrates with CI/CD pipelines, and works across browsers.
Selenium lets testers simulate user interactions like clicks, form inputs, and page navigation, helping ensure applications function as expected across browsers and devices.
What is Selenium in Automation Testing?
Selenium is an open-source suite of tools for automating web browsers. It supports multiple programming languages including Java, Python, C#, and JavaScript.
Selenium Components:
- Selenium WebDriver: Core component to control browsers programmatically
- Selenium IDE: Chrome/Firefox extension for record-playback testing
- Selenium Grid: Enables parallel test execution across multiple environments
Benefits of Using Selenium for Automation:
- Supports all major browsers and OS
- Works with many languages (Java, Python, etc.)
- Integrates with frameworks like TestNG, JUnit, and CI tools like Jenkins
- Easily scalable using Selenium Grid
- Large community and rich documentation
Basic Selenium Test Lifecycle:
- Setup WebDriver for a chosen browser (e.g., ChromeDriver)
- Locate Web Elements using locators (e.g., ID, XPath, CSS)
- Perform Actions like click, sendKeys, submit
- Assert Results using testing frameworks (e.g., TestNG)
- Generate Reports and clean up test data
Common Locators in Selenium:
| Locator Type | Syntax Example |
| ID | driver.findElement(By.id(“email”)) |
| Name | driver.findElement(By.name(“username”)) |
| XPath | driver.findElement(By.xpath(“//button[text()=’Submit’]”)) |
| CSS Selector | driver.findElement(By.cssSelector(“input[type=’text’]”)) |
| Class Name | driver.findElement(By.className(“btn”)) |
Best Practices for Selenium Automation:
- Use Page Object Model (POM) to manage code maintainability
- Avoid hard-coded waits; use explicit waits instead
- Regularly update WebDriver versions
- Use assertions wisely to validate key functionalities
- Parameterize test data using external files (Excel, JSON, CSV)
