What is the Behavior-First principle in this context?

It focuses tests on observable outcomes that provide value to the user, rather than testing internal implementation details or private methods which increases maintenance burden.

Can this skill help reduce flaky tests?

Absolutely. The review criteria specifically prohibit time-dependent assertions and shared mutable state, which are the primary causes of non-deterministic test results.

Does this skill help with test file organization?

Yes, it enforces naming conventions such as *.int.test.* for integration tests and *.e2e.test.* for end-to-end tests to ensure clear project structure.

How does this skill calculate test ROI?

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

セキュリティとテスト

Standardizes integration and end-to-end test design using ROI-driven principles and automated skeleton specifications.

This skill provides a comprehensive framework for designing high-impact integration and end-to-end tests within Claude Code. It implements a behavior-first philosophy that prioritizes user-observable outcomes over implementation details, ensuring that testing efforts deliver maximum business value. By utilizing a specific ROI calculation, standardized test skeletons, and EARS format mapping, the skill helps developers maintain lean, efficient CI/CD pipelines while enforcing strict quality standards like AAA structure and deterministic execution.
