Selenium IDE is an open-source record and playback test automation extension for Chrome, Firefox, and Edge browsers, allowing developers to make simple recordings of their actions as they navigate a web application or web page, then turn the recordings into scripts that can be exported to WebDriver code using various frameworks. The tool offers improved features such as cross-browser support, parallelization, multiple locators, flow control with conditional logic and looping, code generation, and synchronization commands, making it a valuable test asset for web automation. With its simplicity, power, and scalability, Selenium IDE is an ideal low-code solution for creating functional tests, especially for users looking to minimize flakiness and increase test resiliency.
