The UI I'm working on is rendered differently based on the response received. I would like to test the UI when a `4xx` and `5xx` responses are received.

My api handler looks something like:

```
import { rest } from 'msw';
import { items } from './apiValues';

export const handlers = [
  rest.get('/items/', (_req, res, ctx) => res(ctx.status(200), ctx.json(items))),
];

```

This will always return a `2xx` response making it unable to test the UI if a `4xx` or `5xx` response is received, unless I change the handlers manually, which is tiring.

How can tests for `4xx` and `5xx` responses be tested?
