sagas: unit vs integration tests

integration.js

import { createAction } from 'redux-act';
import { call, takeLatest } from 'redux-saga/effects';
import { createStore, applyMiddleware } from 'redux'

import api from './api';

const action = createAction('action');

function *doSomething() {
  yield call(api);
}


function *daemon() {
  yield [takeLatest(action.getType(), doSomething())]
}

/*   tests   */

function getStoreForSaga(saga) {
  const sagaMiddleware = createSagaMiddleware()
  const store = createStore(
    () => {}, // TODO: put real reducer there
    applyMiddleware(sagaMiddleware)
  )
  sagaMiddleware.run(saga)
  
  return store;
}

descrive('saga', () => {
  beforeAll(() => {
    jest.mock('./api', () => Promise.resolve());
  });
  
  it('should call api', () => {
    const store = getStoreForSaga(daemon);
    
    store.dispactch(action());
    
    expect(api).toHaveBeenCalled();
  });
})

unit.js

import { createAction } from 'redux-act';
import { call, takeLatest } from 'redux-saga/effects';

import api from './api';

const action = createAction('action');

function *doSomething() {
  yield call(api);
}


function *daemon() {
  yield [takeLatest(action.getType(), doSomething())]
}

/*   tests   */

descrive('saga', () => {
  it('should call api', () => {
    const iterator = daemon();
    iterator.next();
    
    expect(
      interator.next(action()).value
    ).toEqual(
      call(api)
    )
  });
})

UPDATE: Actually, I'm not sure this is all that different from the unit tests.
