javascript - 使用enzyme对antd的Form组件进行单元测试遇到的问题

Question

antd+redux+enzyme，测试antd提供的Form组件时有问题了
Login=Form.Create()(LoginForm) => A=Form.Create()(B)
想测试原生的B，可是B经过Form经过一层封装，里面的getFieldDecorator()函数又必须依赖Form创建完成后的A才行，因此mount(B)是编译不通过的，必须mount(A)才编译通过，可是我的期望是在编译期间设置B的props和context属性，来测试B的componentWillMount(里面用到props,context)，这样似乎没办法做到，太坑了。
是不是测试antd组件无法用enzyme测试?

测试代码：
import React from 'react';
import { expect } from 'chai';
import { mount, shallow, render } from 'enzyme';

import { Login, LoginForm } from '../../login/Login';

describe('<Login />', () => {

    it('Login componentWillMount', () => {
        const props = {
            action: () => {},
            auth: {},
            loading: false,
            loginErrors: undefined,
            isAuthenticated: false,
        };

        const context = { 
            router: { push: function(route) { this.route = route }, route: '', clear: function() { this.route = '' } }, 
            store: {} 
        };

        const component = mount(<LoginForm {...props} />,{ context });

        expect(component.context().router.route).to.equal('');

        component.setProps({
            isAuthenticated: true,
        });

        expect(component.context().router.route).to.equal('/app');

    });
});

报错代码：
<Login /> Login componentWillMount:
