Acceptance Test-Driven Development (ATDD) is a collaborative, test-first development methodology that focuses on defining acceptance tests before the actual development of features or functionalities begins. ATDD involves collaboration among stakeholders, including customers, developers, testers, and business analysts, to create a shared understanding of the desired outcome of a feature or product. The acceptance tests are written in the stakeholders’ language, ensuring clarity and alignment on the expected behaviour of the system.
