Selenium, a powerful open-source tool, facilitates automated functionality testing and has gained substantial admiration off late. This tool executes JavaScript, renders pages, and retrieves webpages in a mockup of human work to check if the website is working well, as it should across various browsers and operating systems. Decked is a run-down of why testers and quality professionals prefer Selenium over other tools for web functionality testing:
Ease of Use
Selenium offers an intuitive, user-friendly interface for creation and execution of test suites.
The real task of writing and maintaining scripts with Selenium is also really relaxed. The tool allows ascertaining elements from the browser, making it easy to write the tests using the specific identifiers of the element. Selenium has a customary set of guidelines such as click (on an element), open (a URL), type (into an input box), and a set of verification commands that allow the user to specify the expected behavior or values. It makes it easy to perform every browser action, including the otherwise complex events like onKeyPress or onMouseOver.
Flexibility
Selenium supports flexible test architectures.
Many testers prefer keeping tests as independent and autonomous as possible for the sake of resilience and maintenance. This allows them to move the tests around, refactor them or delete them whenever required. Refactoring the tests reduce replication of the test codes and intensify the maintainability of the test suite.
Easy Add-Ons
Selenium is a powerful tool that covers almost all the aspects of web functionality testing. The scope is also increased by the means of various add-on tools. Selenium IDE allows the users to navigate their application in Firefox and record their actions forming tests.
