Test Driven Development


TDD shortens the programming feedback loop whereas AMDD shortens the modeling feedback loop.
TDD provides detailed specification (tests) whereas AMDD is better for thinking through bigger issues.
TDD promotes the development of high-quality code whereas AMDD promotes high-quality communication with your stakeholders and other developers.
TDD provides concrete evidence that your software works whereas AMDD supports your team, including stakeholders, in working toward a common understanding.
TDD “speaks” to programmers whereas AMDD speaks to business analysts, stakeholders, and data professionals.
TDD is provides very finely grained concrete feedback on the order of minutes whereas AMDD enables verbal feedback on the order minutes (concrete feedback requires developers to follow the practice Prove It With Code and thus becomes dependent on non-AM techniques).
TDD helps to ensure that your design is clean by focusing on creation of operations that are callable and testable whereas AMDD provides an opportunity to think through larger design/architectural issues before you code.
TDD is non-visually oriented whereas AMDD is visually oriented.
