# TestBox BDD Primer TestBox is a xUnit style and behavior-driven development (BDD) testing framework for CFML (ColdFusion). It does not depend on any other framework for operation and it has a clean and descriptive syntax that will make you giggle when writing your tests. It ships with not only the xUnit and BDD testing capabilities, but also an assertions and expectations library, several different runners, reporters and MockBox, for mocking and stubbing capabilities. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
