unit-testing

Table-driven unit tests with Vitest automate validation of domain models by running inputs through it.each tables. This approach covers multiple scenarios succinctly while keeping tests fast and expressive without over-mocking.

A minimal-mock strategy in unit testing validates domain logic and pure utilities by mocking only essential external boundaries. This keeps tests fast and expressive while verifying behavior across multiple table-driven cases without over-mocking.

Yes, you can use test-driven development to implement pure functions with Vitest by extending table-driven test cases using it.each. This approach applies minimal mocks to verify expected behavior across multiple input scenarios succinctly.

Yes, Vitest is required to automate table-driven testing for pure utilities. The framework provides the it.each functionality needed to run multiple input scenarios and validate behavior using a minimal-mock approach.

Use a table-driven approach over standard unit tests when covering multiple input scenarios for domain models and pure utilities. It keeps tests succinct and expressive by validating behavior across cases without duplicating test logic.

Over-mocking makes unit tests for domain logic less effective by hiding pure behavior behind stubs. A minimal-mock strategy ensures tests remain fast and expressive while verifying actual logic across table-driven input scenarios.
