我正在尝试为我的API生成 Istanbul 尔代码覆盖率。我已经研究了SO中的许多答案以及 Istanbul 尔的文档，但没有任何对我有用。 Mocha 测试运行良好，一切都通过了，甚至 Istanbul 尔也在创建 coverage 文件夹，但它没有在其中创建报告。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。下面是我的 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 cover ./node_modules/.bin/_mocha
最佳答案
对于我的node.js(typescript)项目，我使用这种脚本进行测试+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即可启动
编辑:
对于 Istanbul 尔:
第 1 步 - 在 Istanbul 尔下运行您的服务器
$ ./node_modules/.bin/istanbul cover --handle-sigint server.js
第 2 步 - 运行测试，无需在 Istanbul 尔下运行
$ ./node_modules/.bin/_mocha -R spec ./.instrument/test/** --recursive
完整报告位于coverage/lcov-report/index.html
关于node.js - Istanbul 尔没有生成 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/
