In this blog, we shall discuss grid selenium, what is selenium grid, selenium node, and why selenium automation testing is a demanding career. So, to become a selenium tester, you can join Selenium Training in Bangalore to acquire an in-depth understanding of What is Automation Testing, OOPs concepts in java, etc.
Why Selenium is demanding tools
Among various tools such as Katalon Studio, Appium, TestComplete, Cypress, Ranorex Studio, Perfecto, LambdaTest, Postman, SoapUI, Eggplant Functional, Tricentis Tosca, Apache JMeter, Robot Framework, Protractor; Selenium is a top automation tool for software testing.
Moreover, individuals who have completed their selenium automation testing have wider opportunities in many IT companies, as we mentioned above. They obtain a typical role as a software test engineer, Software Manual Testing, senior software taser, senior software taser, Automation Test Lead with Python & Selenium Experience, Automation Tester - Java/Selenium, etc.
To become a software test engineer, you can join Software Testing Course In Bangalore to have precise understanding of mobile testing, web testing techniques, etc.
With the shift from traditional software development to DevOps and other fast-paced projects, test environments are increasingly important to ensure that systems function correctly. Organizations' ability to effectively forecast and manage testing capacity is still inadequate in the current testing environment. In this case, performance testers are theoretically well-positioned to assist.
Nonetheless, they are generally wary about projecting capacity, as more capacity consumption can result in significant annual expenditures. The software testing environment has changed dramatically in recent years, with Test Automation evolving to allow quick software releases while maintaining good quality. Automation has always been a popular trend because it reduces time spent on routine testing and speeds up the process.
Now, we shall discuss grid selenium, what is selenium grid, the selenium node, and how AI is incorporated with automation testing.
AI in Software Testing
Moreover, To accomplish the purpose of self-testing. Artificial intelligence (AI) must become an intrinsic aspect of software testing tools. Every test cycle produces a large amount of data that can be utilized to discover and resolve test failures. The data from each test run get sent back to the AI algorithms. With the growing benefits of incorporating AI into testing, the need for technology has risen.
Now, we shall discuss what is Selenium, selenium grid, and Selenium for automation testing in detail.
What is Selenium?
Selenium is an automated testing framework.
You can use multiple programming languages like Java, C#, Python etc to create Selenium Test Scripts.
Selenium Test Scripts can be written in a variety of programming languages, including Java, C#, Python, and others.
Selenium Software is a software package that caters to an organization's various Selenium Quality assurance needs. The following is a list of tools.
Why do we use Selenium for Automation Testing?
One of the most widely used automation testing technologies is Selenium. Automation testing is transforming any manual testing process into test scripts with the help of automation tools like Selenium.
-
Selenium test scripts can be developed in a variety of programming languages, including Java, Python, C#, Ruby, and Perl.
-
Selenium test scripts can be run on various operating systems, including macOS, Linux, Unix, Windows, and others.
-
The test scripts can be run on a variety of browsers, including Chrome, Safari, Firefox, Opera, Internet Explorer, and others.
-
Selenium can be used with other testing tools such as TestNG and Junit to handle test cases and produce test reports.
-
Selenium is linked with Maven, Jenkins, and Docker testing tools to achieve continuous testing.
Now, we shall discuss the selenium grid, what is selenium grid, and the selenium node in detail.
What is Selenium Grid?
Selenium Grid is a Selenium functionality that allows you to execute test cases on several machines and platforms. The local machine is in charge of activating the test cases, and once they are activated, the remote device executes them automatically. Assume you have five test cases. You wish to complete your test cases on a remote machine because your local machine is running numerous applications. The remote server must be configured to run the test cases there.
It allows for the execution of tests to be distributed. Initially, you will have a host server on which you will write the test cases and run them. In a large corporation, however, you may have several test cases, and it is not capable of running all of them on the same system. In a large corporation with several servers, the test cases are distributed throughout the machines/servers by the local machine.
The architecture of Selenium Grid
Hub is classified into four test cases; the four test cases are classified into Node 1 Firefox on Ubuntu, Node 2 IE on Windows, Node 3 Safari on Mac, and Node 4 Android.
Hub
-
A Hub is a central point or local machine that receives and distributes test requests to the appropriate nodes. Hub is the machine that starts the test.
-
In a selenium grid, there must be just one Hub.
-
The test scenario is initiated by the machine containing the Hub; however, the browser will be automated on other systems.
Node
The testing phase that you uploaded on the Hub will be executed by nodes, which are selenium instances. Nodes may be run on a variety of machines using multiple platforms and technologies.
What is the purpose of Selenium Grid?
The following are some of the reasons why Selenium Grid is beneficial:
Run-on several platforms: The test cases can be run on a variety of systems, making it platform agnostic. For instance, suppose you have a hub with Internet Explorer 9. Many outdated websites support Internet Explorer 9; therefore, Hub has it. We now wish to execute the test cases on a variety of platforms, including Internet Explorer. A computer can only have one version of a browser installed, as we all know. You must configure the node to which your test cases will be sent.
You can run numerous cases at the same time if you set up the Selenium Grid. This reduces the amount of time it takes to run the program.
How to set up Selenium Grid
To execute the Remote Selenium web driver, install the Selenium Standalone Server. It can be downloaded as a single jar file.
-
Place the jar file anywhere on your hard drive.
-
Open the command prompt.
-
A command prompt is used to register the Hub.
-
Further, java -jar selenium-server-standalone-3.8.1.jar -role hub is the command to use. The machine will be treated as a hub using this command.
You have understood the hub address from the above image and open the link where the server resides.
The above screen shows that the Hub has been constructed, but Hub has not been authenticated with the nodes. The nodes must now be authenticated with the Hub.
-
Log on to another computer and set it up as a hub node. You can use Teamviewer to connect your machine to another computer remotely. You can connect the node with your Hub from the node machine, but not from yours, so I connected my server to another machine. Run "java -jar selenium-server-standalone-3.141.59.jar role webdriver -hub >ipaddress>/grid/register -port 5566" on a node machine.
-
To execute the test cases in Google Firefox or Chrome, we'll need to install the chrome driver or geekodriver on a node computer. To do so, we'll need to use a node machine and perform the following command:
-
"java -Dwebdriver.chrome.driver="D:\chromedriver.exe" -jar selenium-server-standalone-3.141.59.jar role webdriver -hub >ipaddress>/grid/register -port 5566"
The letter D stands for command-line parameters. If you type D, the command assumes it has only one parameter, and you must use caution while executing the test cases. It is required to have a browser's exe file. We can't run the Selenium test cases without the exe file.
Now, you would have understood what is selenium grid, selenium node, selenium grid, and how to set up Selenium Grid. So, to have a comprehensive understanding of selenium testing, you can join Selenium Training in Chennai to understand automation, manual, testing tools, and the Advantages and Scope of Automation Testing.
