summary

Argues for running fast experiments directly on the domain model by combining example mapping with business-focused TDD and mob-style "code storming". Shows a live JUnit/Jupiter Spring project for a CrowdSorcery fundraising case, iterating tests that emit domain events to discover rules (age check, criminal record, verification threshold at $10,000). Produces working tests and a whiteboard model in ~30–60 minutes, yields concrete questions for domain experts and short feedback loops instead of costly prototypes.
