Acceptance Test Driven Development
Acceptance Test Driven Development (ATDD) is a collaborative software development methodology where acceptance criteria for a feature are defined as automated tests before development begins. It involves stakeholders, developers, and testers working together to create executable specifications that verify the software meets business requirements. This approach ensures that development efforts are aligned with user needs and reduces misunderstandings about feature expectations.
Developers should use ATDD when building complex applications with clear business requirements, as it helps prevent scope creep and ensures features deliver real value to users. It is particularly valuable in agile environments where frequent feedback and iterative delivery are essential, such as in e-commerce platforms or financial systems where precise functionality is critical. ATDD also reduces rework by catching requirement mismatches early in the development cycle.
