ReduxForm需要将store作为道具传递给测试

Question

我正在尝试使用ReduxForm进行一些单元测试，我显然有像这样的最简单的问题。

实际上，我有一个搜索栏，当我修改它的输入时，我需要状态来反映该数据。

我写了这个测试:

beforeEach(() => {
      const store = configureStore()({
        searchBar:{
          inputField:''
        }
      });
      searchBar = TestUtils.renderIntoDocument(<SearchBar store={store}/>);
    });
it('should have a form Field tag', () => {
      const input = TestUtils.findRenderedComponentWithType(searchBar, Field);
      expect(input).toBeTruthy();
    });

应该测试这个:

import React from 'react';
import { Field, reduxForm } from 'redux-form';
/**
 * The seach bar component class definition
 */
class SearchBar extends React.Component {
  /**
   * Render the searchBar component
   */
  render() {
    return (
      <form>
        <Field name="inputField" component="input" type="text"/>
        <button type="submit">Rechercher</button>
      </form>
    );
  }
}
/**
 * Decorate the form
 */
SearchBar = reduxForm({
  form: 'searchBar'
})(SearchBar);
export default SearchBar;

但是我已经抛出了以下错误:

Invariant Violation: Could not find "store" in either the context or props of "Connect(ConnectedField)". Either wrap the root component in a <Provider>, or explicitly pass "store" as a prop to "Connect(ConnectedField)". in src/index.spec.js (line 3551)

即使我把组件中的props传递给它…(参见beforeEach调用)

有什么想法吗?

要测试redux-form，您需要有一个redux存储和一个提供程序。

试试这样:

searchBar = TestUtils.renderIntoDocument(<Provider store={store}><SearchBar /></Provider>);
