用笑话和酶进行测试-潜水不是功能

Question

试图从酶中复制dive()的例子，但继续得到TypeError: wrapper.find(...).dive is not a function

代码：

class Bar extends React.Component {
  render() {
    return (
      <div>
        <div className="in-bar" />
      </div>
    );
  }
}

class Foo extends React.Component {
  render() {
    return (
      <div>
        <Bar />
      </div>
    );
  }


it('renders correctly', () => {
  const wrapper = shallow(<Foo />);
  expect(wrapper.find('.in-bar').length).toBe(0);
  expect(wrapper.find(Bar).length).toBe(1);
  expect(wrapper.find(Bar).dive().find('.in-bar').length).toBe(1);
});

.dive()已添加到酶v2.5.0中：
