When one plans to optimize the evaluation of web applications, Selenium is the very first thing that comes to mind. Selenium is a useful device since it is not only free software, but also a web application portable software testing platform that supports multiple languages such as Java, C#, Ruby, Python. Selecting the correct language depends on the testing application, the support group, the test automation frameworks available, reliability, elegance, and, of course, seamless integration of the construction.
The step by step tutorial on how to kick-start Selenium with Java is illustrated in this post.
Why Developers prefer Selenium With Java?
Java has been supported by a good group of developers to produce documents and solve problems to be the most favored programming language among app developers. Therefore, the writing of selenium test cases using Java has numerous advantages:
- Selenium supports Java. The active group of contributors and comprehensive documentation can also be leveraged by testers to write test cases.
- Programs written in Java are quicker than Python and other common languages.
- Compared to other programming languages such as Python, Java is more widely used in business applications, making it easier to integrate Selenium tests.
Eventually, the choice of the correct language varies according to the project, organization, and personalities who operate it. When dealing with Selenium, an important requirement is to know the language in depth.
Getting Started with Selenium using Java
One needs to put the multiple aspects together to Learn Selenium with Java, to begin testing.
Selenium is available for Windows, Linux, Solaris, Macintosh, and various operating systems (OS). Different browsers such as Chrome, Safari, IE, Edge and Firefox are also assisted. It can be used to optimize practical tests. In order to achieve a continuous test plan, Selenium is also easy to integrate with devices like Jenkins, Maven, and Docker. Tools such as TestNG and JUnit further help to structure selenium tests for ease of maintenance and report production.
We explain how to set up and maintain a quick test with Java bindings through Selenium in this segment.
Pre-requisites for Setup Configuration
The following elements are needed to obtain begun with automation:
- Selenium Client and WebDriver Language bindings
- Building and Running the first test
- Configuring Selenium Webdriver with Eclipse

What is WebDriver?
WebDriver is a network automation structure that enables you to achieve your tests toward various browsers, not just Firefox, Chrome (unlike Selenium IDE).
WebDriver additionally permits you to utilize a programming language in building your analysis scenarios (not possible in Selenium IDE). You can immediately apply conditional operations like if-then-else or switch-case. You can further play looping like do-while.
Following programming languages are held by WebDriver
You ought not to understand any of them. You simply require to be trained in one. Yet, in this tutorial, we wish to be utilizing Java with Eclipse as our IDE.
The distinction among Selenium RC and Webdriver
Before the appearance of WebDriver in 2006, there was a different, automation device called Selenium Remote Control. Both WebDriver and Selenium RC hold the subsequent characteristics:
- They both let you utilize a programming language in outlining your test scripts.
- They both enable you to control your searches upon different browsers.
So how do they differ? Let us discuss the answers.
WebDriver’s plan is more comfortable than Selenium RC’s.
- It necessitates the browser from the OS level
- All you require are your programming language’s IDE (which includes your Selenium requirements) and a browser.
3. Real-life Interaction
WebDriver combines with page components more realistically. For instance, if you own a mutilated text box on a surface you survived questioning, WebDriver literally cannot access any content in it just as whereby a real person cannot.
Selenium RC’s API is extra grown but includes repetitions also often confusing commands. For instance, most of the time, testers are worried about whether to use type or type keys; or whether to use click, mouseDown, or mouse down at. Worse, various browsers represent all of those commands in diverse methods too! WebDriver’s API is easier than Selenium RC’s. It does not include excessive and complex commands.
5. Browser Support
WebDriver can hold the headless HtmlUnit browser HtmlUnit is termed as “headless” because it is an ideal browser – it is GUI-less. It is a really fast browser because no experience is consumed in serving for page components to place. This stimulates your analysis of performance cycles.
Since it is undetectable to the user, it can simply be managed by automatic centers.
Selenium RC cannot help the headless HtmlUnit browser. It requires a firm, evident browser to work on.
