Why Use Selenium Alternatives?
While Selenium WebDriver allows the creation of test scripts in a wide array of programming and scripting languages, gaining proficiency in its intricate details can require a substantial time investment.
Although Selenium is still one of the cornerstones of automated testing, it has its limitations. We will compare alternatives like BugBug, Cypress, and many more to assess functionalities, costs, and business compatibility.
How to Use Selenium?
Selenium is an open-source automation tool that revolutionized web application testing by providing a powerful platform to automate browsers. It allows developers and testers to write test scripts in numerous programming languages, including Java, Python, Ruby, and JavaScript, to run automated tests that mimic user interactions with web applications.
The Selenium suite has several components:
Selenium WebDriver
WebDriver is the heart of the Selenium project. It provides a programming interface to create and run test scripts that emulate user actions on web browsers. WebDriver interacts directly with the browser without any intermediary, unlike Selenium Remote Control (the deprecated part of the project that required a server).
It supports a wide range of browsers including Chrome, Firefox, Internet Explorer, and Safari, and it can be used with a variety of programming languages such as Java, C#, Python, Ruby, and JavaScript.
Selenium IDE (Integrated Development Environment)
This is a browser extension for Firefox and Chrome that allows for record-and-playback of user interactions with the browser. It's a quick tool to create test cases without writing code, which is very useful for beginners or for creating tests on the fly.
However, the tests created with Selenium IDE are typically less robust and more prone to breakage with application changes than those written with WebDriver.
