Question

我有一个业力配置，用于我的单元测试和代码转换。我的项目目录如下所示

RootFOlder
-karma.config.js
-webpack.test.config.js
-src/
--test.ts
--components
---ButonComponent
----Buttoncomponent.spec.ts

我的karma.config在下面

// Karma configuration

module.exports = function (config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',


    // frameworks to use
    // available frameworks: https://npmjs.org/browse/keyword/karma-adapter
    frameworks: ['jasmine'],


    // list of files / patterns to load in the browser
    files: [
      'src/test.ts',
      'src/components/**/*.component.ts',
    ],

    // list of files / patterns to exclude
    exclude: [
      'node_modules',
      './src/tsconfig.spec.json'
    ],
    plugins: [
      require('karma-jasmine'),
      require("karma-coverage"),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-webpack'),
      require('karma-sourcemap-loader'),
      require('ts-loader')
    ],


    // preprocess matching files before serving them to the browser
    // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor
    preprocessors: {
      'src/components/**/*.ts': ['coverage'],
      'src/components/**/*.component.ts': ['webpack', 'sourcemap'],
      'src/test.ts': ['webpack', 'sourcemap'],

    },

    webpack: require('./webpack.test.config'),

    coverageReporter: {
      reporters: [
        { type: 'text', subdir: 'text' },
        { type: 'html', subdir: 'report-html' },
      ]
    },

    ...
    ...
  });
}

还有我的webpack。 module.exports = { devtool：“ inline-source-map”，模式：“发展”，目标：“节点”，解决：{ 扩展名：['.ts'，'.js'] }

  module: {
    rules: [
      {
        test: /\.ts$/,
        loaders: ['ts-loader', 'angular-router-loader', 'angular2-template-loader']
      }
     ....
     ....

    ]
  },

  plugins: [
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV || 'test')
    }),
    // Removes warnings regarding Critical dependency
    new webpack.ContextReplacementPlugin(
      /\@angular(\\|\/)core(\\|\/)f?esm5/, path.join(__dirname, './src')
    )
  ],
  node: {
    console: false,
    global: true,
    process: true,
    Buffer: false,
    setImmediate: false
  }
}

问题是我运行测试后，我的研究覆盖了捆绑的node_modules。文件覆盖率最终以MBytes为单位运行，覆盖率很低。请问我该如何排除我的node_modules？任何帮助表示赞赏。

Answer 1

默认情况下，您甚至不需要在node_modules路径中提及exclude。尝试将其删除，看看覆盖范围是否得到纠正？

如果没有，

尝试将其添加到preprocessors：

'!node_modules/**/*.*': ['coverage']

因果报应包括node_modules
