Usage in close-to-real SSR environment?

[xobotyi]

Is there any way to test SSR functionality in environment close to real SSR?

I'm testing the hook that should fallback to noop during SSR, the hook declaration itself, as for now i'm checking SSR by testing window type: typeof window !== 'undefined'. Like this:

export const myAwesomeHook = typeof window === 'undefined' ? ()=>{} : ()=>{/*some real hook code*/}

When testing with jest in it's common env (jsdom) window object is obviously exists and there is no way to test that everything will be fine in SSR, since i gaij browser version of a hook.
If to switch environment to node, ssr tests failing with

    The error below may be caused by using the wrong test environment, see https://jestjs.io/docs/en/configuration#testenvironment-string.
    Consider using the "jsdom" test environment.

    ReferenceError: document is not defined

       7 |
    >  8 |     renderHook(() => myAwesomeHook());
         |     ^
       9 |

In this case renderHook improted from server: import { renderHook } from '@testing-library/react-hooks/server';

Hi @xobotyi, thanks for raising this issue. I think it's being caused by this line:

react-hooks-testing-library/src/server/pure.ts

Line 16 in ef1d731

const container = document.createElement('div')

We should move that into the hydrate function so we reference document when they want it to render for real.

Are you interested in submitting a PR for this @xobotyi?
