testing Cursor ruleA
testing from thedaviddias/llms-txt-hub is a Cursor rule: instructions the Cursor agent follows in that repo.
mdr add thedaviddias/llms-txt-hub/.cursor/rules/testing.mdc@git:20250301.62fad3cPins git:20250301.62fad3c in mdr.lock. Pin the fingerprint instead.

Rules for writing Jest tests in TypeScript.
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
# Jest Testing Guidelines
## File Organization
- Place tests next to the file being tested with `.test.ts(x)` extension
- Or use `__tests__` directory in the same folder as the tested file
- Match the folder structure of the source code
## Test Setup
### Custom Test Renderer
Always use the custom test renderer to ensure consistent provider wrapping and test utilities located in test/test-utils.tsx
```
// Re-export everything
export * from '@testing-library/react'
export { render }
```
Usage in tests:
```typescript
import { render, screen } from '@/test/test-utils'
describe('Component', () => {
it('should render correctly', () => {
render(<Component />)
// ... rest of test
})
})
```
## Test Structure
Follow this structure for all tests:
```typescript
describe('ComponentName or FunctionName', () => {
describe('specific functionality or scenario', () => {
it('should describe expected behavior', () => {
// Arrange
// Act
// Assert
})
})
})
```
### Example of Good Test Structure
```typescript
// Good: Clear structure and naming
describe('useAuth', () => {
describe('when user logs in', () => {

How to install
mdr add thedaviddias/llms-txt-hub/.cursor/rules/testing.mdc@sha256:b8856a5274b6ac8dThe line at the top of this page pins the label git:20250301.62fad3c, 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.
