JGiven is a developer-centric Behavior-Driven Development (BDD) tool for Java. Scenarios are written in plain Java with a fluent Java API - Neither text files, nor Groovy is needed. Method names are parsed at runtime and define the scenario text - No duplicate text in annotations is needed. Scenarios are executed by either JUnit or TestNG - No extra test runner is needed, thus JGiven works with all existing IDEs and build tools for Java out-of-the-box
