Cucumber Open
Cucumber Open runs automated acceptance tests from specifications written in plain language, helping teams check whether software behaves as described. It supports Behaviour-Driven Development by executing Gherkin specifications saved in `.feature` text files, typically alongside software in source control. Step definitions link the specification's steps to code that carries them out. Official implementations include JavaScript, Java, Ruby, Android Java, Kotlin, Scala, and C++, with semi-official and unofficial implementations also listed. Gherkin has variations for spoken languages, so teams can use keywords in their own language. Reporting options include built-in HTML, JSON, JUnit, and progress formatters, as well as custom formatters. Cucumber can run in continuous integration environments; its documentation describes JUnit output and a Jenkins reporting plugin. The project is free and open source, with local execution, parallel execution, browser testing, and API access. Published Cucumber Reports are public without authentication and deleted after 24 hours; the report service says data is stored in US data centers and encrypted at rest.
