React / Redux测试错误：传递给createStore的initialState参数是意外类型

Question

尝试在react / redux套件中运行测试后，我收到以下错误。我确保我使用redux-immutable作为回购时的文档建议，但无济于事。

The initialState argument passed to createStore is of unexpected type. Expected argument to be an instance of Immutable.Collection or Immutable.Record with the following properties:

我正在使用Immutable.JS()

Reducers文件：

import { combineReducers } from 'redux-immutable';
import dashboard from '../Dashboard';
import budget from '../Budget';
import { reducer as formReducer } from 'redux-form/immutable';
import { syncHistoryWithStore, routerReducer } from 'react-router-redux'

const rootReducer = combineReducers({
  form: formReducer,
  dashboard,
  budget
});

export default rootReducer;

存储文件

import {createStore, applyMiddleware, compose} from 'redux';
import thunk from 'redux-thunk';
import reducers from './reducers';

export function configureStore(){
  // Use redux dev tools if available, otherwise use default composition;
  const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

  const store = createStore(reducers, {}, composeEnhancers(
    applyMiddleware(thunk)
  ));

  return store;
}

的尝试

我在store文件中尝试过以下操作，因为我不知道错误是什么，但它仍然无效。

  const store = createStore(reducers, Immutable.collection({form: "", dashboard: "", budget: ""}), composeEnhancers(
    applyMiddleware(thunk)
  ));

我也尝试了以下内容：

https://github.com/gajus/redux-immutable

  const store = createStore(reducers, Immutable.Map(), composeEnhancers(
    applyMiddleware(thunk)
  ));

我尝试制作一个记录不可变对象

  const StateRecord = Immutable.Record({
    "form": "form",
    "dashboard": "dashboard",
    "budget": "budget"
  });

  const store = createStore(reducers, StateRecord, composeEnhancers(
    applyMiddleware(thunk)
  ));

Answer 1

不幸的是，我应该提供我的测试运行器，因为它是问题的根源。将新提供程序呈现到我的组件中..

Test Runner Snippet

<Provider store={createStore(reducers, Immutable.fromJS(state))}>
  <ComponentClass {...props} />
</Provider>

看起来像

<Provider store={createStore(reducers, (state))}>
  <ComponentClass {...props} />
</Provider>
