SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill resolves the common issue where test suites drift from the actual implementation, leading to false positives, outdated assertions, or brittle tests that fail due to minor refactors.

Core Features & Use Cases

Implementation-First Discovery: Automatically traces call chains and I/O to ensure tests reflect current code behavior rather than stale assumptions.
Contract-Based Rewriting: Generates a clear checklist of observable behaviors before modifying any test code.
Use Case: When a legacy module has tests that are failing or confusing, use this skill to map the current implementation logic to a new, clean set of test cases that accurately verify the module's contract.

Quick Start

Invoke the test-helper skill to analyze the current directory and rewrite the test cases to match the implementation.

FAQPage Schema

How do I align outdated unit tests with current code behavior after refactoring?▼

Implementation-first discovery traces source code call chains and I/O to ensure tests reflect current behavior rather than stale assumptions. It maps actual implementation logic to verify the module's contract before rewriting any test code.

What is the best way to fix failing legacy module tests that are decoupled from production logic?▼

Contract-based rewriting generates a clear checklist of observable behaviors before modifying any test code. It ensures new test cases accurately verify the module's contract by mapping current implementation logic instead of patching brittle assertions.

Can I use this test alignment approach for both unit and integration testing workflows?▼

Yes, this approach applies to both unit and integration testing workflows where test suites have become decoupled from production logic. It systematically discovers call chains and verifies test coverage against implementation branches.

How do I automatically rewrite test suites to match implementation branches?▼

Invoke the test-helper skill to analyze the current directory and systematically rewrite test cases to match the implementation. It traces call chains, defines contracts, and verifies test coverage against implementation branches automatically.

Why do my test suites fail with false positives after minor code refactors?▼

Test suites drift from actual implementation over time, leading to false positives, outdated assertions, or brittle tests that fail due to minor refactors. Aligning test cases with current system behavior resolves this decoupling issue.

What are the limitations of rewriting test cases to match implementation logic?▼

Rewriting test cases to match implementation logic risks validating incorrect behavior if the production code itself is flawed. Contract-based rewriting mitigates this by defining observable behaviors first, ensuring tests verify the intended contract.
