Property Testing

Property testing with fast-check validates business logic invariants by running assertions against many random inputs, ensuring calculations and state transitions hold across edge cases. It integrates directly with Vitest to execute these property tests.

Property-based testing verifies that invariants hold across a wide range of generated inputs, reducing brittle example-based tests. Use it to validate complex calculations, constraints, and state transitions by defining properties rather than specific scenarios.

Yes, property testing applies to unit, integration, and domain tests. You can validate state transitions and constraints in domain logic by generating random inputs with fast-check arbitraries and asserting invariants hold after operations.

Fast-check provides common arbitraries like integers, floats, strings, arrays, and objects to generate random inputs. You use these arbitraries to feed calculations and assert that specific invariants remain valid across real-world scenarios.

Use fast-check property tests to validate batch data invariants within livestock-management workflows. This approach automatically generates edge case inputs to verify calculations and state transitions without writing manual test scenarios.

Yes, fast-check is required as a testing dependency to generate arbitraries and run property tests. You also need Vitest configured as your test runner to execute the resulting property-based test suite.
