Can I use this for table-driven tests?

Absolutely. The skill prioritizes table-driven tests as the idiomatic Go pattern for testing multiple scenarios within a single test function.

Does this skill support interface mocking?

Yes, it provides detailed patterns for using testify/mock to define mock implementations, set expectations, and verify call counts for Go interfaces.

What is the difference between assert and require in this skill?

The skill uses 'require' for prerequisites that should halt the test upon failure and 'assert' for independent checks where multiple failures can be reported at once.

How does this help with the TDD cycle?

It guides the user through writing a failing (Red) test first, followed by minimal implementation (Green), and finally optimizing code while maintaining test passes (Refactor).

Security & Testing

Implements Go unit tests and mocks using the Testify framework following Test-Driven Development best practices.

About

This skill empowers Claude to write idiomatic Go tests using the popular stretchr/testify library. It provides a comprehensive framework for implementing Test-Driven Development (TDD) workflows, including the Red-Green-Refactor cycle. Developers can leverage expert guidance on choosing between assert and require packages, creating robust interface mocks, organizing complex test suites, and structuring table-driven tests. It is specifically designed to improve Go codebase reliability and test coverage while maintaining clean, readable code structures.
