Question

我在尝试对使用react-highcharts的React组件进行基本的烟雾测试时遇到了问题。我使用基本Jest的典型方法会产生错误：

it('renders without crashing', () => {
  const div = document.createElement('div');
  render(<MyComponent {...props} />, div);
});

从一些互联网调查来看，这似乎是将<ReactHighcharts />渲染为子组件的固有问题。如何在不重组我的组件或使测试复杂化的情况下解决这个问题？

由于问题是将<ReactHighcharts />渲染为子组件，而我们只是想确保父组件不会爆炸，我们可以使用Enzyme的shallow方法仅渲染没有孩子的父组件：

it('renders without crashing', () => {
  expect(shallow(<MyComponent {...props} />).exists()).toBeTruthy();
});
