Use for test lifecycle hooks: beforeAll, afterAll, beforeEach, afterEach, fixtures, preload.
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
# Bun Test Lifecycle
Bun supports Jest-compatible lifecycle hooks for test setup and teardown.
## Lifecycle Hooks
```typescript
import { test, expect, beforeAll, afterAll, beforeEach, afterEach } from "bun:test";
let db: Database;
let testData: any;
// Runs once before all tests in file
beforeAll(async () => {
db = await Database.connect();
});
// Runs once after all tests in file
afterAll(async () => {
await db.close();
});
// Runs before each test
beforeEach(() => {
testData = { id: 1, name: "test" };
});
// Runs after each test
afterEach(() => {
testData = null;
});
test("example", () => {
expect(testData.name).toBe("test");
});
```
## Hook Execution Order
```
beforeAll
├── beforeEach
│ └── test 1
│ └── afterEach
├── beforeEach
│ └── test 2
│ └── afterEach
afterAll
```
## Nested Describe Hooks
```typescript
import { describe, test, beforeAll, beforeEach, afterEach, afterAll } from "bun:test";
describe("outer", () => {
beforeAll(() => console.log("1. outer beforeAll"));
afterAll(() => console.log("6. outer afterAll"));
beforeEach(() => console.log("2. outer beforeEach"));
afterEach(() => console.log("5. outer afterEach"));

How to install
mdr add secondsky/claude-skills/bun-test-lifecycle@sha256:70111d8d38fbd57dThe line at the top of this page pins the label v1.0.0, 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.
