Invalid hook call after `jest.resetModules` for dynamic `require`s

I have also been running into this issue in a particularly nasty way. We use the resetModules config option globally, so tricks around calling jest.isolateModules() don’t work well. Instead, I came up with a workaround that globally excludes React from jest’s resetModules behavior.

In a file specified in the setupFiles config option, add the following:

let mockActualReact;

jest.doMock('react', () => {
  if (!mockActualReact) {
    mockActualReact = jest.requireActual('react');
  }
  return mockActualReact;
});

This sets up a mock for React that lazily loads the actual React, and always returns the result of the first initialization. This could also be generalized to implement a set of modules that are globally excluded from resetModules.

Generalized version:

const RESET_MODULE_EXCEPTIONS = [
  'react',
  'react-redux',
];

let mockActualRegistry = {};

RESET_MODULE_EXCEPTIONS.forEach(moduleName => {
  jest.doMock(moduleName, () => {
    if (!mockActualRegistry[moduleName]) {
      mockActualRegistry[moduleName] = jest.requireActual(moduleName);
    }
    return mockActualRegistry[moduleName];
  });
});

Personally, I’ve found this to be a useful construct, and now that the React hook issue is more prevalent, it might be good to have a version of this built in to Jest as something like a persistentModules or excludeFromResetModules option.

@kapral18 We are also experiencing the same issue. Have you found a work around for this?
