SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps teams establish rigorous testing practices for DomainLang projects, making it easier to design strategies, generate unit and integration tests, and ensure high test coverage.

Core Features & Use Cases

  • Test Strategy Design: Define comprehensive test plans aligned with project goals.
  • Vitest Unit & Integration Tests: Create clear, fast tests that verify behavior across modules.
  • Coverage & Edge Case Exploration: Propose scenarios to push boundaries and ensure resilience.
  • Documentation of Testing Practices: Capture conventions and templates to enforce consistency across the team.

Quick Start

Activate the tester skill and begin by outlining a Vitest suite for your target module, then generate AAA-compliant tests using the mandated templates from .github/instructions/testing.instructions.md.

FAQPage Schema
How do I write robust Vitest tests using the AAA pattern?

To write robust Vitest tests using the AAA pattern, structure your test suites into clear Arrange, Act, and Assert phases. This enforces behavior-focused validation over implementation details, ensuring high code coverage and thoughtful edge case exploration across your modules.

What's the best way to design a test strategy for unit and integration tests?

Designing a test strategy for unit and integration tests requires defining comprehensive test plans aligned with project goals. You establish this by capturing conventions in mandated templates to enforce consistency, ensuring both fast unit tests and thorough integration coverage across features.

How do I improve code coverage and explore edge cases in my test suites?

Improve code coverage and explore edge cases by generating scenarios that push module boundaries and verify behavior. This approach proposes targeted edge case scenarios to ensure resilience, moving beyond basic implementation details to validate true feature behavior across your project.

Can I use this to generate testing templates and documentation for my team?

Yes, you can generate testing templates and documentation to capture conventions for your team. This enforces consistency across testing practices by leveraging published instructions, ensuring all team members follow the same rigorous Vitest test generation standards for DomainLang projects.

Does Vitest testing work with DomainLang projects without extra dependencies?

Vitest testing works seamlessly with DomainLang projects without requiring extra dependencies. You can directly outline a Vitest suite for your target module and generate AAA-compliant tests using the mandated templates from your project instructions file.
