Introduction

 

Selenium is one of several popular open-source Web UI (User Interface) automation testing suites used to validate web applications across various browsers and outlets. Selenium is an open-source umbrella scheme for a range of tools and libraries for supporting browser automation. It provides a playback tool for creating relevant tests across most current web browsers without the need to understand an exam scripting language.

 

The interface permits corresponding test writing in various programming languages on web applications distributed across several media and browsers. It produces a single interface that lets you understand test writing in programming languages like Java, Ruby, NodeJS, Python, PHP, C#, and Perl, among others, as language bindings have been processed by Selenium designers to provide compatibility for many languages.

 

 

Tools used in Selenium

 

Selenium is fundamental and consists of four different tools, each with its own set of specific characteristics. The four different tools are the following:-

 

  • Selenium Remote Control: Selenium RC is a significant component of Selenium. It is a testing framework that enables testers and designers to write test scripts in a variety of vocabularies in order to automate front-end UI testing issues. It has a customer library and a server that begins and ends browser sessions by default.

 

  • Selenium Grid: Selenium Grid is a "smart" representative server that makes it effortless to execute similarity on numerous devices. It is done by routing orders to isolated web browser representatives, where one server serves as the hub. This hub paths test orders in JSON form to numerous registered Grid nodes.

 

  • Selenium IDE: Selenium IDE is an open-source test industrialization device that can register and play back your activities on the web. By operating it, you can automate trials for web applications. Manual testers who carry out their trial procedures can benefit from the device due to its appropriate components.

 

  • Selenium WebDriver: Selenium WebDriver is a web framework that allows you to achieve cross-browser testing. It is used to automate web-based application testing to ensure that it works as expected. Selenium WebDriver permits you to select a programming language to build test scripts.

Use of Selenium in Java

 

Selenium is the most prominently used freeware and open-source automation tool. The advantages of Selenium for test automation are numerous. Notably, it supports registration and playback for experimenting with web applications and can run multiple scripts across multiple browsers. Furthermore, Selenium supports Java. So, testers can leverage the involved community of supporters and clear documentation to document test subjects.

 

Programs registered in Java are more rapid than other famous languages like Python. It guarantees high-quality web applications that are progressive, responsive, or regular. Thus, testers like operating Selenium because it's straightforward to develop test scripts to validate functionality.

 

 

Why is Selenium preferred over Java?

 

Selenium and Java are a flawless combination to execute mechanical tests on different web servers. Java is the most frequently selected language by experts who operate Selenium daily. Some of the explanations for why Selenium picked Java are:-

 

  • Online Java Program has an extended web of energetic software developers who donate to corresponding test subjects. It allows the Java residents to expand and the Selenium testers to work.
  • The implementation of programs is more rapid in Java as compared to any other programming language.
  • Today, Java is more popular than other languages, so combining the Selenium tests with Java is constantly healthier.

 

 

Benefits of Selenium with Java

 

Some of the advantages of the Selenium testing instrument that make it the most useful among further automation testing instruments are as follows:-

 

  • Selenium is an open-source automation testing tool that is unrestricted and free to operate.
  • Selenium allows testers to be more flexible when registering complex and developed test issues.
  • Supports test scripts documented in user-preferred languages such as Java, C#, Perl, Python, PHP, and Ruby.
  • It also helps test case implementation on multiple working systems such as Linux, Windows, Android, iOS, and Mac.
  • Supports testing on other web browsers such as Chrome, Firefox, Internet Explorer (IE), Opera, and Safari.
  • Test cases run while the server window minimizes.
  • Selenium is combined with TestNG and JUnit to develop test information and execute test cases.
  • Selenium is integrated with Jenkins, Docker, and Maven to achieve constant testing.

 

 

How to Use Selenium With Java in Simple Steps

 

These are the steps that must be followed to use Selenium with Java:-

 

Java Installation:- The foremost and most basic necessity to write and execute Java programs is a Java Development Kit (JDK), which contains JRE, or Java Runtime Environment.

To download and install Java, all you need to do is:-

 

  • Download Java
  • Install Java 
  • Set the environment's path.

 

Once this is done, to confirm, head to the command prompt and type "java -version." If Java is successfully established, it will display the version of Java sitting on your computer.

 

 

Eclipse Installation:- There is constantly a demand for a platform where designers can write and execute their codes, and one such platform, or IDE, is Eclipse. Eclipse is one of the most sought-after Java IDEs across the globe.

To download and install Eclipse, you are required to go to their authorized website and download it. After extracting the downloaded files, an "eclipse.exe" icon will appear in the Eclipse folder.

Now, all you need to do to launch Eclipse is open that.exe file.

 

 

Selenium Client and WebDriver Language Bindings:- Selenium WebDriver supports a wide range of languages, each of which has its own custom driver. Since we are concerned about Java, we need the Selenium Java Client Driver.

You must go to the official Selenium website to download the customer driver. There, you can see several customer drivers involving different languages that Selenium supports:

 

 

Configuration of Selenium WebDriver with Eclipse:- To begin with, it is the most notable stage. The actions to configure Selenium WebDriver with Eclipse are:

Launch Eclipse (by double-clicking on the eclipse.exe file) and construct a workspace. Then, create a unique Java project.

File > New > Java Project

Then, once the project is started, right-click on the project and form a package beneath it.

Package: New

Then, right-click on the package and construct an unknown class.

Class: New

 

After the class is created, it is time to add the Selenium JAR files to the project.

To add jar files:

Right-click on the project folder and go to properties. In the dialogue trunk that occurs, navigate to the Java Build Path. Click on "Add External JARs Folder" and go to properties. In the dialogue trunk that occurs, navigate to the Java Build Path. Click on "Add External JARs." Then count the jar files downloaded and click on "Apply and Close."

Now, Eclipse is all set to accomplish any Selenium test script.

 

 

First Test Using Selenium with Java

 

The foremost script that we include and operate here is an easy script that extends "facebook.com" on the Chrome browser. To use the Chrome browser, it is required to keep the driver executable. To get the driver executable: Go to the authorized Selenium website and go to the third-party driver browser section. Then download the executable for the detailed browser. After it is downloaded, all you need to do is set the code in your Eclipse window.

 

 

Conclusion

 

Selenium is, of course, the best in the domain to support Java Full Stack Developer with automation testing. Therefore, the need for Selenium Web Testers is on the rise, and it is only going to increase exponentially in the future.
