玩笑看到测试套件，但默默地忽略了测试

该问题是指在NUXT/VUE V2项目中的嘲笑测试。单元测试按预期进行，无论是通过还是不通过。经过一些更改后，玩笑停止运行我的测试（既不通过也没有失败）。

----------|---------|----------|---------|---------|-------------------
File      | % Stmts | % Branch | % Funcs | % Lines | Uncovered Line #s
----------|---------|----------|---------|---------|-------------------

Tests:       0 total
Snapshots:   0 total
Time:        3.454 s, estimated 10 s
Ran all test suites.

我删除了一些我不需要的代码，我藏着更改并再次尝试，但是没有任何测试西服运行。我检查了项目版本，该项目以前按预期进行了测试。仍然什么都没有。

我什至可以做一个空的测试套件，跑步者不会提出“您的测试套件必须至少包含一个测试”例外。这涉及两个测试/单位目录和其他文件夹中的测试。

对于我的提交，我通常有条不紊，但也许我把一些东西弄乱了。我不能排除我在依赖关系树中混合某些东西的可能性，例如，不添加一些至关重要的依赖关系。也许有依赖性不匹配，这是之前没有发生的……

这是什么问题？如何解决此类案例？我以前使用过摩卡咖啡/柴，所以我是新手。

这是我的设置：

jest.config.js

module.exports = {
  moduleNameMapper: {
    "^@/(.*)$": "<rootDir>/$1",
    "^~/(.*)$": "<rootDir>/$1",
    "^vue$": "vue/dist/vue.common.js",
  },
  moduleFileExtensions: ["ts", "js", "vue", "json"],
  transform: {
    "^.+\\.ts$": "ts-jest",
    "^.+\\.js$": "babel-jest",
    ".*\\.(vue)$": "vue-jest",
  },
  collectCoverage: true,
  collectCoverageFrom: [
    "<rootDir>/some-dir/**/*.(js|ts)",
  ],
  testEnvironment: "jsdom",
  testMatch: ["**/*.spec.(js|jsx|ts|tsx)", "**/*.test.(js|jsx|ts|tsx)"],
  runner: "groups",
};

package.json

  "scripts": {
    …
    "test:unit": "jest"
  },
  "dependencies": {
    …
    "core-js": "^2.6.12",
    "nuxt": "^2.15.8",
    "path-to-regexp": "^6.2.1",
    "vue": "^2.6.14",
    "vue-server-renderer": "^2.6.14",
    "vue-template-compiler": "^2.6.14",
    "webpack": "^4.46.0"
  },
  "devDependencies": {
    …
    "@nuxt/types": "^2.15.8",
    "@nuxt/typescript-build": "^2.1.0",
    "@nuxtjs/device": "^2.1.0",
    "@vue/test-utils": "^1.3.0",
    "babel-core": "7.0.0-bridge.0",
    "babel-jest": "^27.4.4",
    "jest": "^27.4.4",
    "jest-runner-groups": "^2.2.0",
    "ts-jest": "^27.1.1",
    "vue-jest": "^3.0.4"
  }
}

原文

The question refers to Jest testing in a Nuxt/Vue v2 project. The unit tests ran as expected, either passing or not passing. After some changes Jest stopped running the tests I had (neither passing nor failing).

----------|---------|----------|---------|---------|-------------------
All files |       0 |        0 |       0 |       0 |

Tests:       0 total
Snapshots:   0 total
Time:        3.454 s, estimated 10 s
Ran all test suites.

I removed some code that I didn’t need, I stashed the changes and tried again, but none of test suits were running. I checked-out to the project version, where the tests previously ran as expected. Still nothing.

I can even make an empty test suite and the runner won’t raise ‘your test suite must contain at least one test’ exception. This involves the tests in both tests/unit directory and in other folders.

I’m usually pretty methodical with regard to my commits, but maybe I messed something up. I cannot exclude a possibility that I mixed something in the dependency tree, e.g. by not adding some crucial dependency to package.json (I removed node_modules and installed it from scratch at some point). Maybe there is a dependency mismatch, which didn’t occur before…

What could be the issue? How to troubleshoot such case? I used Mocha/Chai before so I’m new to Jest.

Here are my settings:

jest.config.js

module.exports = {
  moduleNameMapper: {
    "^@/(.*)quot;: "<rootDir>/$1",
    "^~/(.*)quot;: "<rootDir>/$1",
    "^vuequot;: "vue/dist/vue.common.js",
  },
  moduleFileExtensions: ["ts", "js", "vue", "json"],
  transform: {
    "^.+\\.tsquot;: "ts-jest",
    "^.+\\.jsquot;: "babel-jest",
    ".*\\.(vue)quot;: "vue-jest",
  },
  collectCoverage: true,
  collectCoverageFrom: [
    "<rootDir>/some-dir/**/*.(js|ts)",
  ],
  testEnvironment: "jsdom",
  testMatch: ["**/*.spec.(js|jsx|ts|tsx)", "**/*.test.(js|jsx|ts|tsx)"],
  runner: "groups",
};

package.json

  "scripts": {
    …
    "test:unit": "jest"
  },
  "dependencies": {
    …
    "core-js": "^2.6.12",
    "nuxt": "^2.15.8",
    "path-to-regexp": "^6.2.1",
    "vue": "^2.6.14",
    "vue-server-renderer": "^2.6.14",
    "vue-template-compiler": "^2.6.14",
    "webpack": "^4.46.0"
  },
  "devDependencies": {
    …
    "@nuxt/types": "^2.15.8",
    "@nuxt/typescript-build": "^2.1.0",
    "@nuxtjs/device": "^2.1.0",

  }
}
