Selenium IDE is a longstanding test automation tool known for its user-friendly record and playback functionality that enables users without programming skills to automate testing processes by recording user activities and replaying them. This feature helps in saving time and accelerating software development releases by providing essential test coverage, though it is more suitable for small projects due to its limitations in handling complex or large-scale testing. While Selenium IDE offers a range of commands and the ability to export tests to more advanced frameworks, it struggles with test stability and maintenance, particularly in larger projects, due to its reliance on implementation details and lack of bulk editing capabilities. Despite these drawbacks, Selenium IDE remains a viable option for simple, limited-scope testing, although newer automation tools like testRigor offer more advanced capabilities for comprehensive UI test coverage.
