Question

我在编写测试时迟到了（我还在学习！），并且在我的应用程序上运行笑话测试时遇到了一些问题。尤其是反应导航。

现在我运行npm test时遇到以下问题

不变违反：未设置__fbBatchedBridgeConfig，无法调用本机模块

 at invariant (node_modules/invariant/invariant.js:40:15)
 at Object.invariant (node_modules/react-native/Libraries/BatchedBridge/NativeModules.js:162:3)
 at Object.require [as NativeModules] (node_modules/react-native/Libraries/react-native/react-native-implementation.js:322:12)
 at Object.NativeModules (node_modules/react-native-document-picker/index.js:3:30)

我还遇到了其他一些问题，这些问题已经按照下面显示的代码解决了，但出现了此消息。

我的package.json如下：

"jest": {
    "preset": "react-native",
    "transformIgnorePatterns": [
      "node_modules/(?!(jest-)?react-native|react-navigation|react-navigation-redux-helpers|@react-navigation/.*)"
    ],
    "setupFiles": [
      "./node_modules/react-native-gesture-handler/jestSetup.js"
    ],
    "transform": {
      "^.+\\.js$": "babel-jest"
    },
    "moduleNameMapper": {
      "\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "./__mocks__/fileMock.js",
      "\\.(css|scss)$": "./__mocks__/styleMock.js"
    }

jsetSetup看起来像这样：

jest.mock('react-native-gesture-handler', () => {
  const View = require('react-native/Libraries/Components/View/View');
  return {
    Swipeable: View,
    DrawerLayout: View,
    State: {},
    ScrollView: View,
    Slider: View,
    Switch: View,
    TextInput: View,
    ToolbarAndroid: View,
    ViewPagerAndroid: View,
    DrawerLayoutAndroid: View,
    WebView: View,
    NativeViewGestureHandler: View,
    TapGestureHandler: View,
    FlingGestureHandler: View,
    ForceTouchGestureHandler: View,
    LongPressGestureHandler: View,
    PanGestureHandler: View,
    PinchGestureHandler: View,
    RotationGestureHandler: View,
    /* Buttons */
    RawButton: View,
    BaseButton: View,
    RectButton: View,
    BorderlessButton: View,
    /* Other */
    FlatList: View,
    gestureHandlerRootHOC: jest.fn(),
    Directions: {},
  };
});

global.__fbBatchedBridgeConfig = require('./bridge-mock');

我希望npm test可以运行测试并提供所需的输出。顺便说一句，我正在使用故事书/故事快照。我对为什么文档选择器组件在这里甚至很相关感到困惑，因为我正在使用的一个快照测试中没有引用它。
