用React Native来解决问题

Question

我在尝试运行测试用例代码时遇到错误.我正在使用本机与jest进行反应.在升级0.40之前一切正常.现在是0.42我的所有测试用例都停止工作并且出现错误跟踪错误.

({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import React, { Component, Children, PropTypes } from 'react';
                                                                                             ^^^^^^
    SyntaxError: Unexpected token import

      at transformAndBuildScript (node_modules/jest-runtime/build/transform.js:320:12)
      at Object.<anonymous> (node_modules/react-native-root-siblings/lib/AppRegistryInjection.js:3:22)
      at Object.<anonymous> (node_modules/react-native-root-siblings/lib/SiblingsManager.js:3:27)

这是我的.babelrc代码

{
    "presets": [
        "react-native"
    ],
    "plugins": [
        "transform-decorators-legacy"
    ]
}

什么是我没有得到的问题.

我得到了解决方案

"jest": {
        "preset": "react-native",
        "transformIgnorePatterns": [
          "node_modules"
        ],
        "coveragePathIgnorePatterns": [
          "node_modules"
        ],
        "modulePathIgnorePatterns": [
          "node_modules"
        ]
      },

在我的devDependency中我添加了"react-addons-test-utils", "react-dom",

"devDependencies": {
    "babel-core": "^6.17.0",
    "babel-eslint": "^7.2.1",
    "babel-jest": "^19.0.0",
    "babel-loader": "^6.2.5",
    "babel-plugin-transform-decorators": "^6.13.0",
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "babel-preset-es2017": "^6.16.0",
    "babel-preset-react": "^6.16.0",
    "babel-preset-react-native": "^1.9.1",
    "babel-preset-stage-0": "^6.16.0",
    "enzyme": "^2.8.0",
    "jest": "^19.0.2",
    "npm": "^4.4.4",
    "react-addons-test-utils": "^15.4.2",
    "react-dom": "^15.4.2",
    "react-test-renderer": "^15.4.2"
}

这解决了所有问题。
