TypeError: res.setHeader is not a function about jest-mock-req-res HOT 2 CLOSED

Hi,
I think that the method you're looking for is either .set() or .header(). This package only provides stubs for the explicit interfaces defined in the Express docs; I didn't include methods inherited from the raw NodeJS Request and Response objects, as I usually rely on the higher-level interface provided by Express.

That being said, you can easily extend the mock with additional methods by doing something like the following in your test:

it('should redirect for authentication when user is not logged', async () => {
  const redirectUrl = service.getAuthorization(
    mockRequest({ body: {} }),
    mockResponse({ setHeader: jest.fn() }),
  );
  console.log(redirectUrl);
});

If you'd like to contribute a PR adding stubs for the methods in the base Request and Response objects from NodeJS, I'll be glad to include it in the package.

Thanks!
