  • Model-Based Testing (MBT) replaces hand-written test cases with system behavior definitions.
  • FizzBee generates and runs numerous scenarios, checking implementation against the model.
  • MBT is likened to property-based testing for stateful, concurrent systems.
  • Steps include defining the model, generating scenarios, refinement mapping, and running tests.
  • FizzBee explores interleavings to catch race conditions other MBT tools miss.
  • Test logic is isolated from source code, keeping it clean.
  • Incremental testing allows for immediate validation of new code.
  • FizzBee's tests are deterministic, reproducible, and require no manual review.
  • Every bug comes with a reproducible trace for quick debugging.
  • Benefits include early detection of concurrency bugs and true TDD for stateful systems.
  • Applicable to distributed databases, APIs, microservices, and complex stateful systems.
