rust-testing SKILL.md skillA
rust-testing from kalarislabs/skill-doctor is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add kalarislabs/skill-doctor/rust-testing@git:20260910.eee8645Pins git:20260910.eee8645 in mdr.lock. Pin the fingerprint instead.

How to write Skill Doctor tests — unit, integration, CLI, fixtures, determinism, additive-only. Use when adding tests, fixtures, snapshots, or changing cargo test layout.
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
Canonical policy: `TESTING.md`. Do not invent a second harness.
## Placement
| Kind | Where |
|------|--------|
| Unit | `#[cfg(test)]` next to the code |
| Integration | `crates/<name>/tests/` |
| CLI / exit codes | `tests/cli/` against the compiled binary |
| Fixtures | `tests/fixtures/{benign,attack,hard_negative,evasion}/` |
| Real malware | `tests/fixtures/real_malware/`, `#[ignore]`, `REAL_MALWARE=1` |
## Detector PR checklist (all four)
1. Engine or YARA rule
2. Positive fixture (must fire)
3. Hard-negative (must not fire)
4. Test asserting both
## Always-on property tests
- **Determinism:** two scans, equal SHA-256 of JSON.
- **Additive-only:** L1 CRITICAL + L2 "benign" → CRITICAL remains.
- **Offline:** `--offline` makes zero network syscalls (at least: no `reqwest` constructed).
- **Malformed skill:** does not panic.
## Forbidden
- Network in unit tests.
- `thread::sleep` for sandbox.
- Snapshots with timestamps or absolute paths.
- Live secrets. Use canaries like `AKIA_TEST_CANARY`.
- Speed assertions in the every-commit suite (see `rust-perf`).Read the whole file at its exact version.
How to install
mdr add kalarislabs/skill-doctor/rust-testing@sha256:154820c5fe2800a6The line at the top of this page pins the label git:20260910.eee8645, 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.
