Function: createMockNext()

createMockNext(options?): any

Defined in: mock-next.ts:143

Create a mock next handler that resolves with a successful response.

The returned function is a spy (via createMockFn), so callers can inspect next.mock.calls and next.mock.callCount() after the test.

Parameters

options?

MockNextOptions

Optional overrides for the response payload and stream flag. Every call resolves with its own deep copy of message, so editing one response changes neither the next one nor the supplied object.

Returns

any

a spy-enabled async function resolving to a partial response with stream and message fields. Use a real next response when the code under test reads response headers, trailers, or descriptors.

Example

import { createMockNext } from "@connectum/testing";

const next = createMockNext({ message: { id: 1 } });
const res = await next({});
// res.message => { id: 1 }
// next.mock.callCount() => 1
