Question

我必须尝试以短绒毛打草皮。最初，我试图按照以下步骤进行设置，但这不起作用。

"lint-staged": {
    "*.js": [
      "prettier --write",
      "eslint src/ --fix",
      "npm run test",
      "git add"
    ]
  }

然后我经过一番搜索后将设置更改为以下设置，但这又再次报告了diff错误

"lint-staged": {
    "*.js": [
      "prettier --write",
      "eslint src/ --fix",
      "jest --bail --findRelatedTests",
      "git add"
    ]
  }

错误说明

Jest encountered an unexpected token

  This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

  By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

  Here's what you can do:
   • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
   • If you need a custom transformation to specify a "transform" option in your config.
   • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

当我在终端中运行npm run test时，它工作正常。那么为什么它不能在lint-stage上工作。我在这里做错什么了吗？

Answer 1

您的lint-staged全局模式仅设置为在root上的*.js个文件上运行。您必须将其更改为**/*.js，才能在项目中包含所有*.js文件。

"lint-staged": {
  "**/*.js": [
    "prettier --write",
    "eslint src/ --fix",
    "jest --bail --findRelatedTests",
    "git add"
  ]
}

Answer 2

使用Create React App意味着您必须使用react-scripts进行测试，因为它们具有babel配置，仅凭开玩笑就没了。

有一种解决方法，可以使用react-scripts测试设置多壳的绒毛，并避免弹出和配置自己的babel和jest。

使用软件包 cross-env ，该软件包将允许我们在当前所在的任何环境中配置CI环境变量。

使用以下方式安装：

p_wgt

或

yarn add --dev cross-env

然后在package.json上，您应该具有以下内容：

npm install cross-env --save-dev

如果您使用的是 npm ，则可以将 npm运行测试更改为纱线测试，对于棉绒 strong>。
