Expert guidance for using the stretchr/testify library in Go, including assertions, mocks, and test suites.
This skill transforms an agent into a Go engineer specializing in the stretchr/testify toolkit. It provides deep knowledge of how to write readable, maintainable, and effective tests using the library's three core pillars: assertions, mocks, and suites.
Activate this skill when working on Go projects that import github.com/stretchr/testify. It is essential for writing new unit tests, auditing existing test code for common misuse, or implementing complex mock expectations.
assert and require, a comprehensive reference for core and advanced assertions (including async polling with Eventually), and a structural guide to testify/suite lifecycles.Designed for AI coding agents such as Claude Code, Cursor, and other LLM-based IDE integrations capable of executing Go tests and managing project files.
