SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill ensures your test suites are robust, maintainable, and free from common pitfalls that lead to flaky or brittle tests, ultimately increasing confidence in your codebase.

Core Features & Use Cases

Test Code Analysis: Reviews both E2E (Playwright) and unit (Vitest) tests for design flaws, anti-patterns, and potential issues.
Flakiness Detection: Identifies and helps fix common causes of intermittent test failures.
Use Case: Before committing a significant change to your testing framework, use this Skill to perform a thorough review, catching potential regressions or maintenance burdens early.

Quick Start

Review the recently modified test files for brittleness and anti-patterns.

FAQPage Schema

How do I fix flaky tests in my Vitest unit testing suite?▼

Fix flaky tests by analyzing your Vitest codebase for brittleness, anti-patterns, and isolation issues. This review identifies intermittent failure causes and enforces deterministic behavior to ensure reliable test execution.

What are common anti-patterns in Playwright E2E tests?▼

Common Playwright E2E anti-patterns include design flaws that cause brittleness and flakiness. Analyzing your test code helps detect these issues, validating test coverage and ensuring adherence to test design best practices.

How do I review test code for brittleness before committing changes?▼

Review test code for brittleness by performing a thorough analysis of recently modified test files. This catches potential regressions and maintenance burdens early by validating test isolation and deterministic behavior.

Does this test review process work with both unit and end-to-end testing frameworks?▼

Test review works with both unit and end-to-end frameworks. It analyzes and improves test codebase quality specifically for Vitest unit tests and Playwright E2E tests, mitigating flakiness and brittleness across both.

When should I perform a test code analysis to check for design flaws?▼

Perform test code analysis before committing significant changes to your testing framework. This timing catches potential regressions early, ensuring your test suites remain robust, maintainable, and free of common pitfalls.
