Other than Selenium, one another hot topic is automation testing that has taken the IT world by storm and Selenium certification is one of the best ways to make yourself educated about Selenium and Automation Testing with Selenium.
Automation Testing in Selenium witnesses plenty of benefits and it is frequently used by testers as well. Also, Automation testing can make your work easy and faster than usual. so, without making any delay further, let us learn all about automation testing in Selenium and see how it helps the IT, engineers, to make a project successful.
Selenium is an open-source tool that is generally used for automation testing to be carried out on browsers. Selenium can test web applications only and it is possible testing any software or desktop app using Selenium. You don’t have to panic here because there are many other testing tools that can be used for the same purpose. The objective of this automation testing selenium tutorial is to make you familiar with the benefits of Selenium and how it is suitable for automation testing.

Here are some major features of the tool to keep in mind when opting for Selenium.
Every tool has some benefits and drawbacks. The same is the case with Selenium as well. Let us see when Selenium is not suitable for an IT project.
Before moving further to the automation testing selenium tutorial, you must know how Selenium came into existence. So, let us start our discussion from the beginning like Why do we need software testing, what are the challenges with manual testing, How automation testing is better than the manual testing, Selenium vs QTP or other popular testing tools, and Selenium suite of tools, Writing automation test plan for Selenium, and more.
Today, the world of technology is highly dominated by software programs, apps, and machines worldwide. Do we have the same machines as needed by customers? It can be discovered by testing that particular machine. This is the reason why software testing came into existence.
Take an example of an eCommerce community like Amazon or Flipkart that depends on customers’ traffic heavily on their mobile apps for selling their products. think for a while if something catastrophic happens then it may affect the business outcome negatively. Here, it becomes vital to check the code before deployment that raises the need for software testing further. Selenium is an automation testing tool that aids QA activities and makes things quicker and easy.
Moving ahead, software testing can be divided into two categories: manual testing and automation testing. Most of the time, automation testing is preferred over manual testing to save the overall time and effort. In the next section, we will discuss manual testing and problems associated with manual testing.
Manual Testing is a quality assurance process that all testing activities are conducted manually. It can be done in different environments and you have to record success and failure of each data set separately.
Imagine, if you have to verify the transaction of a website manually. it may cause boredom, time-consuming, and increases manual efforts too. These problems led to the invention of Selenium that is an automation testing tool and overcome all challenges associated with manual testing.

Automation testing has wonderful benefits when compared to manual testing. it is faster and needs less human intervention. It is more accurate and a test plan can be reused when needed. Let us understand a similar concept with the help of an example. Imagine, we have a signup page and we need to check if each signup is made successfully or not. You have to write a piece of code here that could verify all transactions or sign up attempts.
Moreover, it is possible to check test cases under different environments and across multiple browsers. You can automate result files too by scheduling activities at a particular event of time. Also, the report generation process can be automated based on outcomes. The best thing is that automation testing can make the life of a tester easier and simpler. Now, let us see where Selenium stands in the market.
Here we will show the comparison of automation testing Selenium tools with other two popular testing tools QTP and RFT.
|Comparison Parameters||HP QTP||IBM RFT||Automation Testing Selenium|

Automation testing using Selenium is easy when you choose these four selenium components for a particular IT project. You can pick any one of them based on your project needs and requirements.
Selenium Core was the first tool in the Selenium set of tools. It is believed that Selenium Core was not suitable for cross-domain testing because of its same-origin policy. This is the reason how Selenium RC came into existence to overcome this issue. It was a blessing for cross-domain testing and also named as HTTP proxy server that helps in befooling the browser into a belief that both Selenium core and web apps must be tested from the same domain and hence it automatically eliminates the cross-domain testing problem. Further, Selenium RC is divided into two parts to aid the cross-domain testing. These are:
The biggest problem with Selenium RC is that it takes more time for executing a test. Selenium server communicates by using HTTP requests and it is a highly time-consuming process too. Because of its limitations. it has limited applications when compared to Grid and WebDriver.
Another name of Selenium IDE is Selenium Recorder that is generally needed to edit, record, debug, or replay functional tests. Selenium IDE is an extension to the Chrome browser and taken as the add-on for the Firefox browser. When Selenium IDE is integrated within your browser, you could record or export tests in different programming languages.

It is the right time to discuss the Selenium WebDriver component in software testing. It is an enhanced version of the Selenium RC and the most amazing software testing tool too. It is the most trusted tool by testers that accepts commands through client API and further exchanges those commands across browsers.
In brief, the Selenium web driver is a browser-specific component that can be accessed or launched in different browsers. It uses an interface for writing and running automation scripts. Each browser has some drivers that help to run or execute tests further.

The Selenium Grid component is based on hub-node architecture. With the help of the Selenium Grid component in QA testing, it is possible to execute test cases in parallel across multiple browsers. Also, it also selenium scripts to run across different nodes that can be written in different programming languages too.
This component is generally used in the combination of Selenium RC where multiple tests can be executed together on remote machines. Nowadays, people consider WebDriver better than RC and Grid can control both Selenium RC and Selenium WebDriver in automation testing with Selenium.

Now we have a deep idea of Automation Testing Selenium, Selenium components. Let us find various benefits of performing automation testing using Selenium and what makes it stand out in the crowd.
Here is a step by step guide on how to install Selenium on your local system:
Here is one sample script to perform automation testing in Selenium and learn how to write an automation test plan for Selenium. In this example, we will consider using IntelliJ for your reference. You may opt for any other IDE too as needed.
This sample code will quickly launch a web page where you can see find, signup, and login buttons. You have to click the signup/login button and go to the Login page. Once the page is open, add the necessary credentials here and click the login button that will redirect you to the Home page.
The biggest issue when working with Selenium Grid is a web browser. To make it suitable for your local system, you have to upgrade the existing version or install a new one as needed by the project. If there is some web application that you want to test across different browsers and operating systems then Selenium Grid can help.
