import { createMockStore } from 'redux-logic-test';

// specify as much as necessary for your particular test
const store = createMockStore({
  initialState: optionalObject,
  reducer: optionalFn, // default: identity reducer fn(state, action) { return state; }
  logic: optionalLogic, // default: [] - used for the logicMiddleware that is created
  injectedDeps: optionalObject, // default {} - used for the logicMiddleware that is created
  middleware: optionalArr // other mw, exclude logicMiddleware from this array
});
store.dispatch(...) // use as necessary for your test
store.whenComplete(fn) - shorthand for store.logicMiddleware.whenComplete(fn) - when all inflight logic has all completed calls fn and returns promise
store.actions - the actions dispatched, use store.resetActions() to clear
store.resetActions() - clear store.actions
store.logicMiddlware // access logicMiddleware automatically created from logic/injectedDeps props
// allows you to use store.logicMiddleware.addLogic, mergeNewLogic, replaceLogic, whenComplete, monitor$


// So a test might look something like

const store = createMockStore({
  initialState: { foo: 42 },
  logic: [ fooLogic, barLogic ], // logicMiddleware will be created for this logic and injectedDeps
  injectedDeps: { api: myAPI }
});

store.dispatch({ type: FOO });
store.dispatch({ type: BAR });
store.whenComplete(() => { // when logic is finished
  expect(store.actions).toEqual([ // check the actions that were dispatched
    { type: FOO },
    { type: BAR },
    { type: FOO_SUCCESS, payload: [] },
    { type: BAR_SUCCESS, payload: {} }
  ]);
});
