Question

我正在尝试向我的应用添加测试，测试失败并出现以下错误：

测试套件无法运行

TypeError: environment.setup is not a function

  at node_modules/jest-runner/build/run_test.js:71:23

以下是我在项目中使用的配置文件：

.babelrc

{
    "presets": [
        "env",
        "react"
    ],
    "plugins": [
        "transform-class-properties",
        "transform-object-rest-spread"
    ],
    "env": {
        "test": {
            "presets": [
                "env",
                "react"
            ],
            "plugins": [
                "transform-class-properties",
                "transform-object-rest-spread"
            ]
        }
    }
}

jest.config.json

{
    "transform": {
        "^.+\\.jsx?$": "babel-jest"
    },
    "setupFiles": [
        "raf/polyfill",
        "<rootDir>/src/tests/setupTests.js"
    ],
    "snapshotSerializers": [
        "enzyme-to-json/serializer"
    ]
}

的package.json

{
  "scripts": {
    "build:prod": "webpack -p --env production",
    "build:dev": "webpack --env development",
    "dev-server": "webpack-dev-server",
    "test": "jest --config=jest.config.json"

    "react-scripts": "1.0.17",
    "redux": "^3.7.2",

    "webpack-dev-server": "^2.11.1"
  },
  "devDependencies": {
    "babel-jest": "^22.2.2"
  }
}

可能是什么问题，是否有人遇到类似的问题？感谢任何提示：）

添加

"jest": { "testEnvironment": "node" }

到你的package.json文件，它会是这样的：

    .
    .
    .
    "redux-promise": "^0.5.3",
    "sass-loader": "^6.0.6",
    "style-loader": "^0.20.2",
    "webpack": "^3.11.0",
    "webpack": "^3.11.0",
        "webpack-dev-server": "^2.11.1"
      },
      "devDependencies": {
        "babel-jest": "^22.2.2"
      },
      "jest": {
        "testEnvironment": "node"
      }
    }

JEST测试套件因TypeError而失败：environment.setup不是函数
