Editing Unit testing (section)

Using unit-tests as a design specification has one significant advantage over other design methods: The design document (the unit-tests themselves) can itself be used to verify the implementation. The tests will never pass unless the developer implements a solution according to the design.

Unit testing lacks some of the accessibility of a diagrammatic specification such as a [[Unified Modeling Language|UML]] diagram, but they may be generated from the unit test using automated tools. Most modern languages have free tools (usually available as extensions to [[Integrated development environment|IDE]]s). Free tools, like those based on the [[xUnit]] framework, outsource to another system the graphical rendering of a view for human consumption.<ref>GeeksforGeeks. (2024). ''Unit Testing''.
