💡 This Skill includes references (resource) components.

What problem does it solve?

Manually creating and managing unit tests for TypeScript projects is time-consuming and often leads to inconsistent test coverage and missed edge cases. This Skill automates the test-driven development workflow to ensure comprehensive, type-safe unit tests are created efficiently.

Core Features & Use Cases

  • TDD-Aligned Test Design: Generates structured test case lists covering normal, edge, and error scenarios for any target function or feature.
  • Jest + TypeScript Test Generation: Creates type-safe, convention-compliant .test.ts files following project-specific Jest patterns.
  • Use Case: When implementing a new data validation utility in a TypeScript codebase, use this Skill to design test cases, generate the corresponding test file, and run tests to verify coverage before writing implementation code.

Quick Start

Use the tdd-runner skill to design and execute unit tests for the new user profile update function in your TypeScript project.

Frequently Asked Questions about tdd-runner

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate Jest unit tests for TypeScript functions?▼

You design structured test cases covering normal, edge, and error scenarios to ensure comprehensive feature coverage. This approach eliminates inconsistent test design by forcing you to define expected behaviors before writing implementation code.

What's the best way to structure test cases for test-driven development?▼

You design structured test cases covering normal, edge, and error scenarios to ensure comprehensive feature coverage. This approach eliminates inconsistent test design by forcing you to define expected behaviors before writing implementation code.

Does this TDD workflow require a specific Jest configuration for TypeScript?▼

Yes, the TDD workflow requires adherence to Jest configuration standards and type-safe test code practices. Your TypeScript project must follow these conventions to generate valid and executable test files.

Can I use this for expanding test coverage on existing TypeScript code?▼

Yes, you can use this for existing code test coverage expansion in TypeScript projects. It analyzes your target functions and generates the missing edge and error case tests required for robust validation.

How do I handle edge and error cases when designing Jest tests?▼

You handle edge and error cases by applying structured test case design that explicitly categorizes scenarios into normal, edge, and error buckets. This ensures your Jest tests capture unexpected inputs and failure states.
