Selenide

Selenide is an open-source test automation framework for Java and Kotlin that wraps Selenium WebDriver to simplify and stabilize browser-based user interface testing. It provides a concise, fluent API and automatic waiting, reducing boilerplate and flakiness in UI tests. By handling synchronization internally, Selenide allows tests to focus on user actions and verifications rather than explicit waits.

Its core concepts include a SelenideElement wrapper around page elements and high-level helpers such as open(url) and $(selector) for locating elements. Actions (click, setValue, hover) are combined with built-in conditions (visible, present, hidden, text) via shouldBe and shouldHave, enabling expressive test statements like shouldBe(visible) or shouldHave(text("…")). The framework also offers automatic screenshot capture on failure and integrates with standard test runners.

Configuration and usage: Selenide runs on the Java Virtual Machine and can be used with Java or Kotlin tests. It integrates with JUnit and TestNG, and works with common build tools such as Maven and Gradle. It supports multiple browsers, including Chrome and Firefox, in both headed and headless modes, and can connect to remote WebDriver servers. Selenide emphasizes stability and simplicity, and is widely employed in both open-source projects and enterprise environments for end-to-end testing of web applications.
