Getting Started With Selenium



Selenium is an open-source web automation framework for testing a website's functionality. It offers a single interface that enables the creation of test scripts in various computer languages, including Ruby, Java, NodeJS, PHP, Perl, Python, and C#. Selenium tests are then used to verify that the application being tested behaves as expected under different circumstances and user interactions. In this Selenium guide, we explore how to get started with the Selenium framework.


Selenium has made a name for itself over the years, and it's gradually becoming the most widely used software testing tool today. Selenium 4 is the latest version of Selenium. It has developed many new features like easier-to-use IDE and W3C compliance to make programming faster, more efficient, and more convenient.


Are you new to Selenium automation? If so, then Selenium WebDriver is the best way to start. What makes this different from other frameworks is that it gives you everything you need to kickstart your Selenium automation journey in an easy and user-friendly experience.


Selenium has been around for quite a long time and has evolved into a robust testing platform. It offers many different types of testing tools that you can use depending on your requirements. The Selenium IDE allows you to record and playback tests, while Selenium WebDriver allows you to write test scripts in any programming language that supports Java (Java, C#, or Python).


Learn Selenium Major Building Blocks

The Selenium project contains three parts: Selenium IDE, Selenium WebDriver, and Selenium Grid. 


  1. Selenium IDE is an open-source test automation tool that can record and replay your actions on the web. It offers great value to both manual testers and developers alike. A Firefox browser add-on called Selenium IDE facilitates the development of automated web application testing. The Selenium Project created it as a substitute for test scripts written in other computer languages. Selenium IDE differs from its forerunners in that it is a recording tool rather than a tool for creating code. As a result, automation testers can create scripts in any language that the Selenium WebDriver API supports.


  1. WebDriver is the implementation of the Selenium working group that allows for controlling a browser. It is often used for automating web apps and websites to perform various tasks such as clicking buttons, filling out forms, etc.


The following are some of Selenium WebDriver's key attributes:


  • Multiple Browser Support - Selenium WebDriver supports many browsers, including Firefox, Opera, Safari, Internet Explorer, and many more.

  • Performance - Selenium WebDriver works considerably more quickly than Selenium RC.

  • Simple Orders - Selenium WebDriver employs straightforward commands that are simpler to understand and put into practice.



3. Selenium Grid is a smart proxy server that enables you to run tests in parallel on multiple machines. You can add and remove nodes dynamically during test execution while letting the hub maintain all the states. This feature also ensures that a node can be brought up or taken down on-demand during test cases without having to change any code or reconfigure anything else.


In the most recent iterations of Selenium 4, the Selenium Grid's architecture has been completely redesigned. The new architecture makes three different ways to execute the Grid possible: Standalone mode, Hub & Node mode, and fully-distributed mode. The Selenium Grid is also primarily used to perform tests concurrently. Selenium allows for parallel tests across many browsers and operating systems.


Conclusion

Selenium testing can also be done through the cloud. You can leverage cloud based Selenium testing platform like LambdaTest to run your automated test suites on an online Selenium grid. Thanks to these cloud-based systems, the Selenium Grid no longer needs to be installed or configured. Additionally, they enable you to switch between different browsers and make it simple to run tests concurrently. With LambdaTest scalable cloud, run test at scale across 3000+ real browsers, devices and operating systems.

Cypress Testing Framework

  The use of software tools to automate the laborious, human-driven process of evaluating and validating software is known as automated testing. Automated testing is a crucial component of contemporary software delivery methods. In essence, it verifies that each member of a software design functions without requiring a person to spend hours performing manual testing while seated in front of a computer. Nowadays, most agile and DevOps software projects start with automated testing.  With the growing need for durable goods with a short time to market, the requirement for reliable test automation solutions has also grown. In terms of web automation and end-to-end UI test automation, Cypress has carved out a niche among testing frameworks. Cypress has enjoyed a lot of success in the recent past. It has been widely used by teams in different environments, like startups and governments. Cypress helps test web and native applications using JavaScript, TypeScript, and Vue.js. Due to ...
