Does it support the native Go fuzzing introduced in 1.18?

Yes, the skill includes implementation patterns for 'go test -fuzz' to automatically discover edge cases and crashes in your logic using seed corpora.

What is the RED-GREEN-REFACTOR cycle in Go?

It is a TDD process where you write a failing test (RED), implement the minimal code necessary to pass (GREEN), and then optimize the implementation while ensuring the tests remain passing (REFACTOR).

How does this skill handle Go benchmarking?

It provides templates for basic benchmarks, sub-benchmarks for different data sizes, and specific patterns for measuring memory allocations using the testing.B type.

Can this skill help with mocking external dependencies?

Absolutely. It utilizes interface-based mocking patterns that allow you to substitute production code with mock implementations during testing without needing heavy external frameworks.

How are table-driven tests structured using this skill?

Tests are structured as a slice of anonymous structs representing test cases, which are then iterated over using t.Run() to provide clear, named subtest results for each scenario.

セキュリティとテスト

Implements idiomatic Go testing patterns and TDD workflows to build robust, high-performance applications with comprehensive coverage.

This skill equips Claude with a deep understanding of Go's testing ecosystem, enabling the generation of high-quality, maintainable test suites. It focuses on the RED-GREEN-REFACTOR cycle of Test-Driven Development and promotes idiomatic Go practices such as table-driven tests, subtests, and interface-based mocking. Whether you are adding fuzz tests for input validation, creating benchmarks for performance-critical code, or managing golden files for complex outputs, this skill ensures your Go projects meet production-grade reliability standards.
