rust-testing-quality skillA
rust-testing-quality is agent-read markdown (skill) from fusengine/agents: Use when writing, organizing, or running Rust tests — unit, integration, doc-tests, proptest, criterion benchmarks, or cargo-mutants. Not for CI pipeline wiring (rust-tooling-cicd)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<objective> This skill covers organizing and running the full Rust test spectrum: unit tests in #[cfg(test)] modules, integration tests in tests/*.rs against the public API only, doc-tests compiled from /// examples, property-based testing with proptest (including committing proptest-regressions/), criterion benchmarks (harness = false), and mutation testing with cargo-mutants as a scheduled quality gate rather than a per-push check. It also covers the nextest doctest pitfall: `cargo nextest run` never runs doc-tests, so `cargo test --doc` must always be paired alongside it — a green nextest run alone is not full coverage. Out of scope: CI pipeline wiring and gate ordering belong to rust-tooling-cicd; non-Rust test suites are not covered. </objective> # Rust Testing & Quality ## Agent Workflow (MANDATORY) Before ANY test work, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Map existing `tests/`, `#[cfg(test)]`, `benches/` 2. **fuse-ai-pilot:research-expert** - Verify current nextest/proptest/criterion docs via Context7/Exa …

How to install
mdr add fusengine/agents/rust-testing-quality@git:20260904.5f1d30fmdr add fusengine/agents/rust-testing-quality@sha256:9dc0df6bfc920b0bPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
