我如何为玩笑测试模拟传单?

How do I mock leaflet for jest tests?

我在 CRA 项目中使用 L.Icon 中的自定义图标。 运行 开玩笑测试时,它一直说 L 未定义。我将如何模拟传单以避免此错误?

我在 leaflet 本身

的类似问题上找到了这个答案
What I can recommend for testing is the following,
 just mock leaflet using this in your test file,
 that is rendering the map component:
jest.mock('leaflet')

And then you place this leaflet mock you can
find in react-leaflet into the jest mocks folder
 (__mocks__/leaflet.js, download the current file from: 
https://github.com/PaulLeCam/react-leaflet/blob/master/__mocks__/leaflet.js)

That should be enough in most cases.
