如何为createSlice ()的extraReducers编写测试( Jest +酶)？

npm install --save-dev jest enzyme enzyme-adapter-react-16 enzyme-to-json

import { configure, shallow } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
import { createSlice } from 'redux-starter-kit';

configure({ adapter: new Adapter() });

describe('createSlice extraReducers', () => {
  it('should handle the increment action correctly', () => {
    // 创建一个测试用的reducer
    const counterSlice = createSlice({
      name: 'counter',
      initialState: 0,
      reducers: {
        increment: state => state + 1,
      },
      extraReducers: builder => {
        builder.addCase('someAction', state => state + 10);
      },
    });

    // 创建一个初始状态的store
    const store = counterSlice.store;

    // 分发一个increment action
    store.dispatch(counterSlice.actions.increment());

    // 断言初始状态是否正确
    expect(store.getState()).toEqual(1);
  });
});

npm test
