test-code SKILL.md skillA
test-code from urmzd/dotfiles is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add urmzd/dotfiles/test-code@git:20260530.d3be4ddPins git:20260530.d3be4dd in mdr.lock. Pin the fingerprint instead.

Testing philosophy, test types (unit, integration, golden, fuzz, property, benchmark, smoke, E2E), per-language conventions (Rust, Go, Python, TypeScript), file organization, fixtures/mocks, CI strategy, and what NOT to test. Use when writing tests, reviewing test coverage, setting up test infrastructure, or deciding what to test. Do NOT use for general implementation patterns or error handling (use write-code) or design-by-contract reasoning (use review-design).
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
# Testing Practices ## Philosophy Test your software, or your users will. - **Test against contracts, not implementations** assert what it should do, not how it does it. Tests that break on every refactor are coupling to internals. - **State coverage > line coverage** exercise meaningful paths and edge cases, not just lines. We intentionally use no coverage tools; percentage targets create false confidence. - **Tests are the first users of your API** if tests are hard to write, the design is wrong. Refactor the interface, not the test. - **Property-based testing finds edges you didn't think of** complement example-based tests with fuzz and property tests where the input space is large. - **Tests should be boring** a test that's hard to read is a test nobody trusts. Inline data, obvious assertions, no clever abstractions. See `review-design` for the underlying Pragmatic Programmer principles (design by contract, pragmatic paranoia). ## Test Types | Type | What It Verifies | When to Use | Codebase Example | |------|-----------------|-------------|------------------| …

How to install
mdr add urmzd/dotfiles/test-code@sha256:ce3c259ac0c85192The line at the top of this page pins the label git:20260530.d3be4dd, 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.
