Jest类型记录测试运行两次，一次用于ts文件，另一次用于js文件。

Question

我开始使用Jest和类型记录编写一些测试，但是我遇到了一些错误，问题似乎是测试运行了两次，一次是针对ts文件，第二次是针对js文件。

类型记录测试通过，但编译后的javascript测试没有通过。

yarn run v1.5.1
$ jest
 PASS  src/__tests__/some.test.ts (7.955s)
  ● Console

    console.log src/lib/google-analytics/ga-api.ts:75
      Succsess!!
    console.log src/__tests__/some.test.ts:42
      { reports: { batchGet: [Function: batchGet] } }

 FAIL  dist/__tests__/some.test.js
  ● Console

    console.log dist/lib/google-analytics/ga-api.js:64
      Reject

  ● it gets a full google analytics report

    No key or keyFile set.

这在ts-玩笑中是正常的还是我错过了一些额外的配置？

Answer 1

这在ts-jest中是正常的还是我遗漏了一些额外的配置？

您应该将roots设置为/src。这里有一个很好的配置

module.exports = {
  "roots": [
    "<rootDir>/src"
  ],
  "transform": {
    "^.+\\.tsx?$": "ts-jest"
  },
  "testRegex": "(/__tests__/.*|(\\.|/)(test|spec))\\.tsx?$",
  "moduleFileExtensions": [
    "ts",
    "tsx",
    "json"
  ],
}

我也只测试.tsx?文件(没有.jsx?) ;)

同样的问题，使用类型记录中的aws，为了防止它，我在jest-config.js中将.js添加到testPathIgnorePatterns属性中。

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
  testPathIgnorePatterns: [".d.ts", ".js"]
};

Answer 3

如果使用IDE，您可能只想禁用在这些IDE中发生的.ts到.js编译，以避免生成给您带来问题的.js文件。
