我正在尝试为我的api生成伊斯坦布尔代码覆盖率。我已经在SO和伊斯坦布尔文档中调查了很多答案，但没有任何结果对我有用。摩卡测试运行良好，一切都通过了，即使伊斯坦布尔也正在创建coverage文件夹，但它并未在其中创建报告。我的应用程序是简单的快速应用程序，我正在使用chai，chai-http和mocha。以下是我的test / app.js文件和package.json文件的代码。

我正在使用以下命令从命令行运行它：
sudo ./node_modules/istanbul封面./node_modules/.bin/_mocha
最佳答案
对于我的node.js（打字稿）项目，我使用这种脚本进行测试和覆盖：
"test": npm-run-all --parallel build:watch cross-env DOTENV_FILE=.env.test nodemon -e ts --exec mocha build/**/unit/**/*.spec.js --recursive --inspect --watch --reporter spec --bail
只需使用
npm run test启动编辑：
对于伊斯坦布尔：
第1步-在伊斯坦布尔下运行服务器
$ ./node_modules/.bin/istanbul cover --handle-sigint server.js
第2步-运行测试，无需在伊斯坦布尔下运行
$ ./node_modules/.bin/_mocha -R spec ./.instrument/test/** --recursive
完整报告位于
coverage/lcov-report/index.html下关于node.js - Istanbul 尔未生成Mocha Chai和Chai-http测试的覆盖范围，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/48587240/
