Test React code that uses @data-client/react: components and hooks that fetch or change data, with mocked responses for loading, error, mutation and polling cases. Covers renderDataHook, MockResolver and fixtures.
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 Patterns (@data-client/test)
These helpers come from `@data-client/test`. If `package.json` doesn't list it, add it as a dev dependency with the
project's package manager (`npm install -D @data-client/test`).
## Hook Testing with renderDataHook()
```typescript
import { renderDataHook } from '@data-client/test';
it('useSuspense() should render the response', async () => {
const { result, waitFor } = renderDataHook(
() => useSuspense(ArticleResource.get, { id: 5 }),
{
initialFixtures: [
{
endpoint: ArticleResource.get,
args: [{ id: 5 }],
response: { id: 5, title: 'hi ho', content: 'whatever' },
},
],
},
);
expect(result.current.title).toBe('hi ho');
});
```
**Options:**
- `initialFixtures` - Set up initial state of the store
- `resolverFixtures` - Add interceptors for subsequent requests
- `getInitialInterceptorData` - Simulate changing server state
**Return values:**
- Inherits all `renderHook()` return values from `@testing-library/react`
- `controller` - Controller instance for manual actions
- `allSettled()` - Wait for all async operations to complete

How to install
mdr add reactive/data-client/data-client-react-testing@sha256:19230ce0a2e474feThe line at the top of this page pins the label git:20261027.486429b, 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.
