What problem does it solve?
TDD with table-driven tests reduces regressions and clarifies requirements by forcing developers to specify behavior as executable tests before implementation, making small iterations predictable and maintainable.
Core Features & Use Cases
- Enforces the Red-Green-Refactor cycle for incremental development.
- Uses table-driven test patterns to cover multiple input scenarios compactly.
- Encourages Japanese test case names and inclusion of boundary and error cases for clear communication in bilingual teams.
- Useful for implementing small functions, library utilities, and deterministic business logic in Go and Python projects.
Quick Start
Create a table-driven test with Japanese case names that covers positive, negative, and boundary cases, write the minimal implementation to pass the failing tests, then refactor the code while keeping all tests green.
