如何在酶/jest中测试ComponentWillMount中的重定向

class MyComponent extends React.Component {
  componentWillMount() {
    if (!this.props.isLoggedIn) {
      this.props.history.push('/login');
    }
  }

  render() {
    return <div>Welcome to the dashboard!</div>;
  }
}

import React from 'react';
import { shallow } from 'enzyme';
import MyComponent from './MyComponent';

describe('MyComponent', () => {
  it('redirects to login if not logged in', () => {
    const mockHistory = { push: jest.fn() };
    const props = { isLoggedIn: false, history: mockHistory };
    const wrapper = shallow(<MyComponent {...props} />);

    expect(mockHistory.push).toHaveBeenCalledWith('/login');
  });

  it('does not redirect if logged in', () => {
    const mockHistory = { push: jest.fn() };
    const props = { isLoggedIn: true, history: mockHistory };
    shallow(<MyComponent {...props} />);

    expect(mockHistory.push).not.toHaveBeenCalled();
  });
});
