Can this skill help reduce test flakiness?

Yes, it enforces strict review criteria for reproducibility and independence, prohibiting shared mutable state and time-dependent assertions without proper mocking.

What is the Behavior-First principle in this skill?

It is a principle that prioritizes testing user-observable behaviors and data integrity over internal implementation details, ensuring tests remain robust even when code is refactored.

How does it handle different types of testing requirements?

It maps requirements using the EARS (Easy Approach to Requirements Syntax) format, providing specific generation approaches for event-driven, state-based, and branch-coverage scenarios.

How does this skill calculate test ROI?

It uses a weighted formula balancing business value, user frequency, and legal requirements against the specific costs of test creation, execution, and long-term maintenance.

Security & Testing

Standardizes integration and end-to-end testing through ROI-driven design, behavior-first principles, and structured test skeletons.

About

This skill empowers Claude to design high-impact integration and end-to-end tests by focusing on business-critical user journeys and observable behaviors. It utilizes a rigorous ROI calculation model to prioritize test creation, provides standardized skeletons with EARS format mapping, and enforces quality standards like AAA structure and isolation to ensure a maintainable, high-confidence CI/CD pipeline while avoiding the pitfalls of low-value, flaky tests.

Key Features

ROI-based test prioritization to maximize business value and minimize maintenance costs
Behavior-first testing approach focusing on user-observable outcomes rather than implementation details
EARS format mapping for clear event-driven and state-based test requirements
Standardized test skeleton generation with detailed metadata and acceptance criteria mapping
Automated review criteria for verifying test independence, reproducibility, and AAA structure
35 GitHub stars

Use Cases

Reviewing existing test quality to identify low-ROI patterns or implementation leakage
Designing a high-coverage test suite for new feature implementations with defined limits
Generating consistent test documentation and skeletons for complex component interactions
