javascript - 开 Jest 没有找到所有测试

Question

Jest 没有找到我的所有测试文件。它忽略一个目录。当我运行 npm run jest:watch 我在 ./server 中的测试及其子目录进行了测试，但在 ./client

中找不到测试

我尝试过的

我尝试创建一个通用测试文件并移动它。我发现它在以下情况下会起作用。 我还尝试过使用文件的直接路径 - 但这不起作用。

可能的原因

我认为这可能与我不寻常的目录结构有关

./client
./server

相对于

./server.js
./other server files..
./client/...client files

或者对我来说尝试从node.js应用程序运行jest并让它查看客户端目录中的文件(其中包含用React编写的应用程序)可能会失败 - 我不关心在其上运行测试 react 组件(仅限模块)。或者，这可能与客户端目录中的 Jest 有关，搞乱了事情。

<表类=“s-表”> <标题> 文件名 ./服务器/中间件 ./ ./客户 <正文> 删除.test.js 由 Jest 发现 由 Jest 发现 未找到

我的设置

我的文件夹结构如下所示

./
./client  (react client app)
./client/package.json
./client/node_modules
package.json
node.modules
./server   (node.js api app)
./server/package.json

我的 Jest 是从 ./package.json 文件运行的。

我尝试过的其他事情

我尝试对我的文件使用直接路径，以下代码有效

"testMatch": ["<rootDir>/server/delete.test.js"],

但是这段代码(在我想要的文件夹中)没有

        "testMatch": ["<rootDir>/client/delete.test.js"],

代码设置

./package.json

{
    "name": "Infoshot",
    "version": "0.0.4",
    "description": "Research Tool",
    "main": "cd ./server && server.js",
    "scripts": {
        "start": "cd ./server && node server.js",
        "server": "cd ./server && nodemon server.js",
        "client": "npm start --prefix ./client/",
        "clientinstall": "npm install --prefix client",
        "dev": "concurrently \"npm run server\"  \"npm run client\"",
        "heroku-postbuild": "cd ./client && NPM_CONFIG_PRODUCTION=false npm install  && CI= npm run build",
        "compile-saas": "node-sass ./client/src/scss/a_main.scss ./server/nodeClient/public/css/main.css -w",
        "test": "jest",
        "test:watch": "npm run test -- --watch"
    },
    "jest": {
        "testEnvironment": "node",
        "testPathIgnorePatterns": [
            "./node_modules"
        ]
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "dependencies": {
        "axios": "^0.21.0",
        "bcryptjs": "^2.4.3",
        "config": "^3.2.2",
        "dotenv": "^8.2.0",
        "ejs": "^3.1.5",
        "enzyme": "^3.11.0",
        "express": "^4.17.1",
        "express-validator": "^6.2.0",
        "ijavascript": "^5.2.0",
        "jest": "^26.6.3",
        "jsonwebtoken": "^8.5.1",
        "mongoose": "^5.7.0",
        "nodemailer": "^6.4.14",
        "nodemailer-sendgrid": "^1.0.3"
    },
    "devDependencies": {
        "concurrently": "^4.1.2",
        "node-sass": "^5.0.0",
        "nodemon": "^1.19.2"
    }
}

删除.test.json

describe.only('DELETE TEST: getDocument', () => {
    test('Say Hi', async () => {
        const bum = 'bum';
        expect(bum).toBe(bum);
    });
});

./client/package.json

正如我之前所说，我认为这无关紧要，因为它不会运行，因为我使用 npm run jest:watch 从 ./server 运行 jest

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "axios": "^0.19.0",
    "config": "^3.3.2",

    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "previewProd": "react-scripts build && serve"
  },
  "jest": {
    "collectCoverageFrom": [
      "src/components/documentEditor/*.js",
      "<rootDir>/server/",
      "!<rootDir>/node_modules/",
      "!<rootDir>/src/index.js",
      "!<rootDir>/src/registerServiceWorker.js"
    ]
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  },
  "proxy": "http://localhost:5000",
  "devDependencies": {
    "@testing-library/react": "^10.4.9"
  }
}

Answer 1

我发现，如果我删除了 ./client/package.json 中所有提及 jest 的内容，并将 ./package.json 替换为

    "collectCoverageFrom": [
            "**/*.{js,jsx}",
            "!**/node_modules/**"
        ]

成功了。
