我在运行测试中有两个错误。我没有解决它：/

节点：v6.11.2
Npm：v3.10.10

第一个错误是无法读取属性“对象”。为空

TypeError: Cannot read property 'Object.<anonymous>' of null

package.json

  "dependencies": {
    "native-base": "^2.3.1",
    "react": "16.0.0-alpha.12",
    "react-native": "0.47.2",
    "react-native-vector-icons": "^4.3.0",
    "react-navigation": "^1.0.0-beta.11",
    "react-redux": "^5.0.6",
    "redux": "^3.7.2",
    "redux-thunk": "^2.2.0"
  },
"devDependencies": {
    "babel-cli": "^6.26.0",
    "babel-eslint": "^7.2.3",

  },
  "jest": {
    "preset": "react-native",
    "transformIgnorePatterns": [
      "/node_modules/(?!native-base)/",

    ]
  }

当我不使用 jest --no-cache 时，抛出这个错误
第二个错误

/usr/lib/node_modules/jest-cli/node_modules/jest-runtime/build/index.js:510
    const wrapper = this._environment.runScript(transformedFile.script)[ ^

【解决方案1】：

也许试试类似的东西。

    "jest": {
    "verbose": true,
    "coverageDirectory": "./coverage",
    "coverageThreshold": {
        "global": {
            "branches": 40,
            "functions": 0,
            "lines": 33,
            "statements": 25
        }
    }
}

并将其添加到脚本中。

"test": "node ./node_modules/jest/bin/jest --coverage",

感谢您的回答。它不相关的报道：/不起作用：/
你应该可以使用我发布的一些结构。不确定 react-native 是否与 Jest 不同。您是否包含了开玩笑所需的所有节点模块？
我不知道：/我在互联网上找到模块：/
