描述错误

与地理定位模块一起使用时，排毒测试崩溃

错误

Error: @react-native-community/geolocation: NativeModule.RNCGeolocation is null. To fix this issue try these steps:
• Run `react-native link @react-native-community/geolocation` in the project root.
• Rebuild and re-run the app.
• If you are using CocoaPods on iOS, run `pod install` in the `ios` directory and then rebuild and re-run the app. You may also need to re-open Xcode to get the new pods.
If none of these fix the issue, please open an issue on the Github repository: https://github.com/react-native-community/react-native-geolocation

环境（请填写以下信息）：

“ react-native”：“ 0.61.1”，
“反应”：“ ^ 16.9.0”，
“ @ react-native-community /地理位置”：“ ^ 2.0.2”，
“排毒”：“ ^ 14.4.1”，

注意

我正在iOS模拟器上运行测试。
地理位置数据库已正确链接，并且可以在运行时正常运行。

请提供解决方案。

嘿@SergejDK，您需要模拟RNCGeolocation本机模块。在根级别上创建一个文件夹__mocks__。在已创建的文件夹中创建另一个文件夹@react-native-community，并在该文件夹中创建一个名为geolocation.js的文件，您必须在其中指定模拟：

export default {
  addListener: jest.fn(),
  getCurrentPosition: jest.fn(),
  removeListeners: jest.fn(),
  requestAuthorization: jest.fn(),
  setConfiguration: jest.fn(),
  startObserving: jest.fn(),
  stopObserving: jest.fn()
};

文件夹结构应类似于：

.
├── __mocks__/
│   │── @react-native-community/ 
│       | -- geolocation.js

如何使用排毒模拟@ react-native-community / geolocation？
