How does this skill help with flaky tests?

It scans code for non-deterministic patterns such as direct dependencies on the system clock, unseeded random values, or reliance on shared external state without proper cleanup.

Is this skill limited to specific programming languages?

While its examples often feature JavaScript, the underlying principles of test design, determinism, and the Test Pyramid are applicable to all modern programming languages.

What is the 'Arrange-Act-Assert' pattern it checks for?

It is a structural standard for tests that separates setup (Arrange), execution (Act), and verification (Assert) to improve test readability and maintainability.

Can it identify specific missing test cases?

Yes, it evaluates business logic branches, boundary values, and error-handling paths to point out exactly where unit or integration tests are missing.

Does it provide actionable feedback?

Yes, it outputs a structured review table highlighting missing coverage, flaky risks, and quality issues with specific recommendations for improvement.

セキュリティとテスト

Analyzes test coverage and code quality to ensure robust, deterministic, and maintainable software suites.

概要

The Code Review Testing skill acts as a virtual Test Engineer within Claude Code, meticulously evaluating test suites for gaps in business logic, edge cases, and error handling. It focuses on identifying non-deterministic 'flaky' tests caused by time or random dependencies while ensuring tests focus on behavior rather than brittle implementation details. This skill is essential for maintaining high-quality codebases, providing structured feedback on unit and integration tests, and ensuring that every new feature or bug fix is backed by reliable verification logic.
