Introduction to Selenium WebDriver

Introduction

Have you ever felt the need of simulating the use of your application by a real-time user? How the various UI components will behave in various scenarios when acted upon by a user? Selenium can serve this purpose by automated testing of the UI components and much more.

Selenium has been around for more than a decade and has been shown to be a reliable automated testing tool. Selenium WebDriver is a powerful tool for testing an application's front end and performing activities in the browser. Selenium tests can be written in a variety of languages, including Python, Java, C#, JavaScript, and others. Selenium WebDriver assists us in ensuring that our application performs as intended when used by a real user.

Selenium WebDriver Core

Selenium WebDriver was created by Paul Hammant in 2006. Selenium WebDriver is the first cross-platform testing framework that allows users to configure and control browsers at the operating system level. It was used to design and run test cases via a programming interface.

WebDriver is a tool for manipulating web components. It supports a number of programming languages, including Java, C#, PHP, and Python. It may also be used to handle tests with frameworks such as TestNG and JUnit.

Selenium WebDriver has a straightforward and easy-to-understand architecture. It supports all common web browsers. It supports headless browsers such as HtmlUnit and PhantomJS.

Components of Selenium Testing

  • When we develop selenium automated tests, we use the WebDriver interface to declare the methods we use. These techniques allow us to control the web browser we're using and choose items from the HTML page we've loaded. 
  • Our test class, of course, must make use of the browser-specific implementation of this interface. The test class manages the web browser that is being used, selects items from the loaded HTML page, and generates assertions for the data discovered in those elements.
  • The driver executable is a browser-specific component that supports either the Selenium WebDriver's JSON wire protocol or the W3C WebDriver specification. It serves as a middleman between Selenium WebDriver and the web browser in use.
  • Automated tests are supported natively by the web browser. It provides an API that allows us to control the user interface of the web application under test from afar. When the driver executable passes Selenium WebDriver queries, it uses this API.

Frequently Asked Questions

1. What is a Selenium WebDriver?
Ans: Selenium WebDriver is a collection of open-source APIs which are used to automate the testing of a web application in the browser.

 

2. What are the advantages of using Selenium WebDriver based automated testing?
Ans: Following are the advantages of using Selenium WebDriver:

  • Open Source.
  • Language Support.
  • Works Across Multiple OS.
  • Cross-Browser Compatibility Testing.
  • Supports Multiple Frameworks and Languages.
  • Cross-Device Testing.
  • Community Support.
  • Easy to Implement.

 

3. What is the Selenium WebDriver interface or class?
Ans: WebDriver is a remote control interface that enables introspection and control of user agents (browsers).

 

4. Why is TestNG used in Selenium?
Ans: TestNG makes automated tests more structured, readable, maintainable and user-friendly. It provides powerful features and reporting. Its high-end annotations like data provider make it easier to scale up, as you perform cross-browser testing across multiple devices, browsers, and their versions.
