Question

我无法在React native expo app中进行Jest快照测试。根据节点模块的设置和配置，我会遇到各种错误。
例如：
* SyntaxError: Unexpected identifier import ...或大约import React来自另一个文件，
* jest encountered an unexpected token import，
*与script_transformer有关的错误。

这是我的package.json

{
  "name": "empty-project-template",
  "main": "node_modules/expo/AppEntry.js",
  "private": true,
  "scripts": {
    "lint": "eslint .",
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",

  },

    "expo": "^31.0.0",

  },
  "devDependencies": {
    "babel-eslint": "^10.0.1",
    "babel-plugin-syntax-class-properties": "^6.13.0",

    "eslint": "^5.9.0",
    "eslint-plugin-import": "^2.14.0",
    "eslint-plugin-react": "^7.11.1",
    "jest-expo": "^31.0.0",
    "react-test-renderer": "^16.7.0"
  },
  "jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
      "node_modules/(?!(pouchdb-react-native|pouchdb-adapter-asyncstorage))"
    ]
  }
}

有人可以将我指向具有Jest快照测试的React-native Expo应用程序的工作仓库。

jest-expo现在支持更好的快照，检查https://docs.expo.io/versions/latest/guides/testing-with-jest/#snapshot-test

使用快照Jest测试配置来响应本机EXPO应用程序
