What is the benefit of specific assertions?

Specific assertions (like checking exact object values) catch actual bugs that generic checks (like checking if a value exists) often miss.

Does this skill support Test-Driven Development (TDD)?

Yes, it is specifically designed to guide the RED phase of TDD, helping you write more effective failing tests before implementation.

What is the recommended test naming convention?

The skill promotes an '[outcome] when [condition]' pattern, such as 'returns empty array when input is null', ensuring the test name acts as a clear specification.

How does this skill handle edge cases?

It provides detailed checklists for common data types including Numbers, Strings, Collections, Dates, and domain-specific constraints like email formats and currency.

セキュリティとテスト

Enforces principles for writing maintainable, outcome-driven tests using industry best practices and comprehensive edge case checklists.

概要

This skill empowers Claude to author high-quality test suites that serve as both documentation and a robust safety net. Based on the principles of BugMagnet by Gojko Adzic, it implements standardized naming conventions (outcome when condition), promotes specific assertions over generic checks, and provides exhaustive edge case checklists for various data types. By utilizing these patterns, developers can ensure their tests are readable, catch specific bugs, and remain maintainable even as the codebase evolves.
