Question

在测试本机模块功能时遇到了一些麻烦。我设法模拟了商店，道具和状态，并调用了模块功能，这是我的测试：

    import React from 'react';
    import { shallow, configure } from 'enzyme';
    import { expect } from 'chai';
    import Adapter from 'enzyme-adapter-react-16';
    import {Login} from '../src/containers/authentification/login'

    configure({ adapter: new Adapter() })
   describe('test login module', () => {

    test('Login fails', () => {
      const store = {
        getState: jest.fn(() => ({credentials:{token: 'token'}})),
        dispatch: jest.fn(),
        subscribe: jest.fn(),
      }

      const navigation = { navigate: jest.fn() };

      const props = {
        navigation: jest.fn(),
        store,
      }
      props.navigation.state = {params: {}}

      const wrapper = shallow(<Login {...props}/>);

        wrapper.update();
        wrapper.setState({driver: 'Kuku', password: 'kuku'})
        const instance = wrapper.instance();

      instance.state.driver = 'dfgdf'
      wrapper.update()
      console.log(wrapper.state(), instance.state)
      expect(instance.loginTry()).toBeFalsy();

    });
});

如我所见，我也在包装器和实例上设置了状态，并且console.log()照原样打印。但是通过运行npm测试，我得到了：

    console.log __tests__/APlication.js:39
      { driver: 'dfgdf',
        password: 'kuku',
        error: null,
        driverInput: '#bdc3c7',
        passwordInput: '#bdc3c7',
        errorText: null } { driver: 'dfgdf',
        password: 'kuku',
        error: null,
        driverInput: '#bdc3c7',
        passwordInput: '#bdc3c7',
        errorText: null }

  ● Login fails

    ReferenceError: code is not defined

      89 | 
      90 |   loginTry() {
    > 91 |     code = this.state.driver;
         |            ^
      92 |     password = this.state.password;
      93 | 
      94 |      LoginRequest(code, password).then((response) => {

在这里我可以忽略什么？应该不应该像以前使用setState那样设置该函数中的状态？
