Selenium Tutorial By Industry Experts

Introduction

When considering web automation testing, several frameworks, such as Selenium, Cypress, PlayWright, Puppeteer, etc., make their way up to the ‘most preferred list of frameworks.’ Hence, when selecting a test automation framework, various parameters are required to be evaluated, like type, complexity, and scale, in association with the framework expertise that is available within the team. Having said that, it’s not surprising that Selenium is the most preferred framework in web development and QA Testing. Because Selenium QA automation tool makes it easy to test applications across different browsers.

For beginners, Selenium WebDriver is the foundation of the Selenium QA automation framework. In today’s Selenium Tutorials for beginners, we’ll dive into what Selenium is, what WebDriver is, the features of Selenium, and much more.

What is Selenium?

Selenium is a popular web-based open source automation testing tool that works amazingly on different web platforms. It started to automate the testing process for web apps, but continuous improvements and technological advancements have taken the platform to new heights. After mastering the tool, you will wonder how it accelerates testing and enhances the software development process. Learn what Selenium is for getting endless opportunities!

What is WebDriver?

WebDriver is one of the essential components of the entire Selenium framework that helps in complete browser-based test automation. It’s a remote control interface component that enables programs to interact and instruct browsers, control DOM elements inside a web document, and administer the User Agent's behavior. 

Selenium WebDriver is a neutral language protocol, which means protocols independent of any language that are used by the Selenium framework to automate testing steps. So, in short, Selenium WebDriver bridges the gap between the Selenium framework and the end browser over which the test is being executed.

Presently. Selenium and Webdriver are typically spoken together and are even used interchangeably to find the same framework, i.e., Selenium WebDriver. But having said that, it has not been the case always. Earlier, Selenium and WebDriver were independent open source projects; however, in 2008, both teams came together to develop a joint project which helped eliminate inherent issues of the then Selenium RC version.

Features of Selenium Automation Framework

Just we’ve discussed the basics of what Selenium is and what WebDrive is; let's now run you through a few of the essential features of the Selenium automation framework 

  • Selenium supports a number of popular programming languages such as - Java, Python, C#, JavaScript, Ruby, PHP, and Perl; by using specific browser drivers.
  •  It is a platform-agnostic test automation framework.
  • Its tests could be executed on a number of browsers like Firefox, Chrome, IE, Safari, etc., as well as operating systems like - Windows 10, macOS, etc. 
  • Parallel testing in Selenium with the help of Selenium Grid offers enhanced browser and test coverage, accelerating the time to market. 
  • You can make the most out of Selenium and associated test automation framework by integrating Selenium with test automation frameworks by virtue of Python, Java, JavaScript, etc.
  • QA engineers can execute Selenium automation tests as a part of a CI/CD pipeline using the Selenium and Continuous integration.
  • By integrating Selenium with various reporting platforms like Extent, Allure, etc., engineers can quickly generate and manage test reports. 
  • When Selenium tests are run in Docker containers, it helps to cut down the test execution time minimizing the differences between various test environments like staging, production, etc.

If you are new to the Selenium WebDriver, then your search ends here. In this tutorial, we have covered all the basics that are used in day-to-day activity while working on the Selenium WebDriver tool. This tool is based on top programming languages, Java and C#, so understanding the WebDriver tool will be easier for you if you know the basics of these languages.

This Selenium WebDriver tutorial is designed for the beginner with little or no experience in the automation world. If you are new to the testing world, we strongly recommend starting with the Software testing training program first, then switching to the Selenium Grid tutorial. Here are some Prerequisites or installations you should know-

  • Download and Install Java 8 (You'll need to have Java 8 to use Selenium 3)
  • Download IDE / Editor (To Create and run your tests)
  • Download Selenium WebDriver

Before you jump directly into writing your first test script in Java, you should know about the Selenium basics first. Let’s discuss the Selenium testing tutorial first; then, we will jump to Selenium WebDriver Tutorial later.

Different Components of Selenium

As discussed earlier, Selenium is a framework, i.e., it’s not a single software but composed of different components. Selenium is available in three popular forms – 

  • The first is Selenium IDE, 
  • The second is Selenium WebDriver, and 
  • The third is Selenium Grid. 

Selenium IDE is a platform that aids in producing test scripts to automate the testing process. The IDE helps quickly fix bugs without putting much pressure on the developers. At the same time, WebDriver is a tool that helps in scaling and distributing scripts across multiple web browsers and helps create web-based automation scripts. 

1. Selenium IDE

Is a framework that helps developers write or develop test cases to make script learning easy. This is a Firefox Plug-in that helps in creating, loading, recording, and editing test cases.

2. Selenium WebDriver

Was designed to give better support for dynamic web pages where certain elements constantly change without reloading the complete web page. As of today, Selenium WebDriver is compatible with almost all browsers present in the web industry and gives terrific support in automating test scripts on browsers. 

Additionally, how to set up projects in Selenium WebDriver and how to start Selenium webdriver entirely depends on the programming language and environment. You can work with different programming languages in Selenium WebDriver, like Ruby, Python, C#, Java, JavaScript, PERL, PHP, etc. Once you set up the project in any programming language, WebDriver starts responding like a standard library. This is a self-contained library that doesn’t require any additional processes to run the installers.

3. Selenium Grid

Allows the users to run parallel test execution and is used along with Selenium RC in order to run parallel tests between various browsers and machines. It's possible to execute simultaneous tests in more than one environment, which saves a lot of time and speeds up the time to market. 

Selenium Grid is founded on the concept of Hub-Node. Up until Selenium 3, the Hub and Node jars were to be started individually. But with Selenium 4, all the essential dependencies have been made available in a single jar file. Hence, when using Selenium Grid on Selenium 4, there’s no need to start the Hub and Node individually.

Setting Up Test Cases in Selenium IDE

Selenium Testing WebDriver Tutorial for the Beginners

How to record a test case depends on your interaction with the website. The record button will add commands to the web page based on your activity. The record button is open by default in Selenium IDE, but you can turn it off in the MENU bar options. A few of the commands inserted by the record button include clicking the link, checking the radio buttons, entering values, etc. The test case verification enables you to verify the properties of a web page with “Assert” and “verify” commands. The context menu has multiple options under the “Assert” and “verify” commands. This is quite simple to decide on the parameters you need to use to verify the web page. You can edit a Selenium test case by adding commands manually. You just have to select the point where you are interested in adding the commands and select the option Insert command. Yes, you can also add comments to the script to increase its overall readability and usability.

Running a Test Case in Selenium IDE

In the earlier section, we just discussed the concept of how to set up a test case. Now, we will check how to run a test case in Selenium IDE. Here is a step-by-step guide to successfully help you with the concept and running a test case.

  • Run Test Cases – For this purpose, simply click on the option “RUN” to start with currently displayed test cases. In Selenium IDE, you can run test cases with a base URL for different domains. We will advise you to use a relative URL, not a base URL, every time you open a new test case.
  • Run Test Suites–Here, you have to select the option “Run All” to start with the test suites loaded recently.
  • Pause Test cases - For this purpose, simply click on the option “Pause” to stop currently running test cases.

  • Set breakpoints in the middle – Setting breakpoints in the middle is easy, where you can stop the running test cases at specific points whenever required. For this purpose, you must choose the command “Toggle Breakpoint” in the Context Menu.
  • Running test cases from the middle – As we have discussed earlier, it is possible to pause test cases at a certain point. In the same way, it is possible to run the test case from the middle. For this purpose, you must choose the command “set start point” in the Context Menu.
  • How to test any single command – For this purpose, you need to double-click on that particular command, and you can modify the same as per your requirements.
  • Defining a test suite in Selenium IDE –As we know, the test suite is a simple collection of test cases that are running in batch continuously. To define all these test cases together to make a test suite, you can simply use an HTML file and write all the test cases there. Every row in the HTML file will include the path to the test case you want to use inside the suite. Here, the path should be defined clearly. Otherwise, it will give an error at the end.

Further, we will have a quick tour of Selenium WebDriver and how software testing professionals can use it.

Selenium WebDriver 3.0 Basics

Selenium WebDriver was designed to give better support for dynamic web pages where certain elements constantly change without reloading the complete web page. As of today, Selenium WebDriver is compatible with almost all browsers that exist in the web industry and gives terrific support in automating test scripts on browsers. 

As you know, plenty of web browsers are available in the market today, like Mozilla, Firefox, Internet Explorers, Chrome, Safari, etc. We have named a few popular web browsers here that are used to execute test cases frequently. As a testing professional, you must decide on a web browser first, as you know how to start Selenium Webdriver, start it to execute test cases on the same. Each web browser is designed differently, so rules for running test cases on each browser are also different. 

A few Selenium tools are not compatible with all web browsers. So, you must be extra careful when deciding on the web browser to work with Selenium WebDriver. For example, if you want to run test cases on Firefox with Selenium WebDriver 3.0, then you need to install a few drivers first to start your work. You can choose other web browsers tool at your convenience. 

Here is a quick syntax to run WebDriver 3.0 on the Firefox browser –

Selenium Testing WebDriver Tutorial for the Beginners

Now, you are ready to start with Selenium WebDriver 3.0 on different web browsers. You can also use Eclipse as your IDE. Here is a brief explanation of how to use Selenium WebDriver with Eclipse IDE.

How to use Selenium WebDriver with Eclipse IDE?

To start scripting with Eclipse IDE, you need to download JDK first and install the latest version of Java as recommended. The next step is downloading Eclipse and installing it on your computer system. Make sure that you have checked out all the permissions carefully. Now open Eclipse and check either Java is installed successfully or not. For this purpose, you have to select options Windows -> Preference options. If you want to check the current Java version installed on your system, you can check it through the command prompt by using the command “java version.” Once you complete all the formalities, this is the right time to start your scripting on the Eclipse editor.
