Question

我已经使用玩笑和酶为反应应用开发了单元测试。我正在使用Jest版本25.7.1。当我运行测试时，它失败并显示以下错误。我不确定为什么它不喜欢import关键字。

FAIL src / components / App.test.tsx ●测试套件无法运行

LiveData

这是我在package.json中最有趣的配置，

D:\Dev\ps-visualizer\ClientApp\node_modules\@svgdotjs\svg.js\src\main.js:2
import './modules/optional/arrange.js'
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

SyntaxError: Unexpected string

tsconfig是这样定义的，

{
    "browser": true,
    "verbose": true,
    "collectCoverageFrom": [
      "src/**/*.{js,jsx,ts,tsx}",
      "!src/**/*.d.ts"

    ],

      "^react-native$": "react-native-web",
      "\\.(css|less|scss|json)$": "<rootDir>/__mocks__/styleMock.js",

    },

      "json",

  }
