react-native - 反应导航：useIsFocused 使用失败测试用例

Question

我将 useIsFocused() 添加到我的文件中以适应焦点事件，例如

文件.js

import { useIsFocused, useNavigation } from "@react-navigation/native"

const navigation = useNavigation()    
const isFocused = useIsFocused()

useEffect(() => {
  getData(somedata)
}, [isFocused])

但是当我运行我的测试文件时，测试失败了

TypeError: navigation.isFocused is not a function

我在这里错过了什么吗？
