Short description: A semi-structured way to write down test cases used for testing in software development
Given-When-Then (GWT) is a semi-structured way to write down test cases. They can either be tested manually or automated as browser tests with tools like Selenium and Cucumber.[1][2]
It derives its name from the three clauses used, which start with the words given, when and then.[3] Given describes the preconditions and initial state before the start of a test and allows for any pre-test setup that may occur. When describes actions taken by a user during a test. Then describes the outcome resulting from actions taken in the when clause.
The Given-When-Then was proposed by Dan North in 2006, as part of behavior-driven development.[4]
