推荐答案

如果您使用<正在访问您的应用程序 http：// localhost 前缀，您需要更新您的jest配置（在 jest.config.js 中），因为，

In case, if you are accessing your application with a http://localhost prefix, you need to update your jest configuration (in your jest.config.js) as,

  "jest": {
    "verbose": true,
    "testURL": "http://localhost/"
  }

如果您还没有任何jest配置，只需在 package.json 中包含配置。例如：

In case you do not already have any jest configuration, just include the configuration in your package.json. For example:

{
  "name": "...",
  "description": "...",
  ...
  "jest": {
    "verbose": true,
    "testURL": "http://localhost/"
  }
}

或 jest.config.js ：

module.exports = {
  verbose: true,
  testURL: "http://localhost/",
  ...
}

或者如果你有项目已配置：

module.exports = {
  verbose: true,

  projects: [{
    runner: 'jest-runner',
    testURL: "http://localhost/",

    // ...
  }]
}
