This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

test-bevy-systems from velimirmueller/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when writing or fixing tests for a Bevy game — headless App/World tests with MinimalPlugins, running one system, asserting messages, observers and state transitions, deterministic time, ordering checks, property tests, and cargo-nextest in CI.

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

# Test Bevy Systems

Bevy 0.20, `cargo-nextest`. Rationale and pitfalls: [testing-patterns.md](testing-patterns.md). Versions: [stack-versions](../_shared/stack-versions.md).

## 1. Audit current state (change nothing)

```bash
cat .claude/stack-profile.md 2>/dev/null                   # tests.layout, task_runner, ci
ls tests/ .config/nextest.toml 2>/dev/null; ls src/lib.rs
grep -rln "#\[test\]" src/ tests/ | head
grep -rnE "DefaultPlugins|WinitPlugin|RenderPlugin" tests/ src/**/tests* 2>/dev/null   # windowed tests: replace
grep -n "nextest\|cargo test" justfile Makefile mise.toml .github/workflows/*.yml 2>/dev/null
cargo nextest --version; grep -n "proptest" Cargo.toml
```

`tests.layout: tests-dir` (default): integration tests in `tests/`, one file per feature. `colocated`: unit tests in `#[cfg(test)] mod tests` next to the plugin; keep integration tests in `tests/` anyway.
No `src/lib.rs` → the game cannot be tested; run [scaffold-bevy-game](../scaffold-bevy-game/SKILL.md) step 5 first.

## 2. Decide what to do
- No tests → add the harness (step 5) and one test per plugin: its main state change.

How to install

The exact contents, by fingerprint
mdr add velimirmueller/claude-skills/test-bevy-systems@sha256:477af2639f1e296c

The line at the top of this page pins the label git:20261009.762665f, 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.
