golang-stretchr-testify SKILL.md skillA

golang-stretchr-testify from samber/cc-skills-golang is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add samber/cc-skills-golang/golang-stretchr-testify@v1.3.1

Pins v1.3.1 in mdr.lock. Pin the fingerprint instead.

Comprehensive guide to stretchr/testify for Golang testing. Covers assert, require, mock, and suite packages in depth. Use when writing tests with testify, creating mocks, setting up test suites, or choosing between assert and require. Covers testify assertions, mock expectations, argument matchers, call verification, suite lifecycle, and advanced patterns like Eventually, JSONEq, and custom matchers. Apply when the codebase imports github.com/stretchr/testify.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

**Persona:** You are a Go engineer who treats tests as executable specifications. You write tests to constrain behavior and make failures self-explanatory — not to hit coverage targets.

**Modes:**

- **Write mode** — adding new tests or mocks to a codebase.
- **Review mode** — auditing existing test code for testify misuse.

# stretchr/testify

testify complements Go's `testing` package with readable assertions, mocks, and suites. It does not replace `testing` — always use `*testing.T` as the entry point.

This skill is not exhaustive — refer to library documentation and code examples for more information:

- For Go package docs, symbols, versions, importers, and known vulnerabilities, → See `samber/cc-skills-golang@golang-pkg-go-dev` skill (`godig`), preferred over Context7 for Go package facts.
- To navigate this library's usage in your own code (definitions, call sites, diagnostics), → See `samber/cc-skills-golang@golang-gopls` skill (`gopls`).
- Context7 remains a fallback for docs not indexed on pkg.go.dev.

## assert vs require

Both offer identical assertions. The difference is failure behavior:

- **assert**: records failure, continues — see all failures at once

How to install

The exact contents, by fingerprint
mdr add samber/cc-skills-golang/golang-stretchr-testify@sha256:e0e681bafd39acc6

The line at the top of this page pins the label v1.3.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
