Karma - 如何指向 typescript 覆盖的源映射

Question

我喜欢使用 karma-coverage 为我的打字稿源文件生成覆盖率报告。我的单元测试是用 javascript 编写的，我使用的是 Jasmine 测试框架。

我的文件夹结构如下：

node_modules/
app/
  app.js
  app.js.map
  app.ts
  components/
  controllers/
      SampleController.ts
  directives/
  filters/
  services/

unittests/
  karma.conf.js
  components/
  controllers/
      SampleControllerTest.js
  directives/
  filters/
  services/

我的 karma.conf.js

module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],
    plugins: [
          'karma-jasmine',
          'karma-ng-html2js-preprocessor',
          'karma-coverage',
          'karma-phantomjs-launcher',
          'karma-sourcemap-loader'

      ],
    preprocessors: {
        '../app/directives/controls/**/*Template.html' : [ 'ng-html2js' ],

            // source files, that you wanna generate coverage for
            // do not include tests or libraries
            // (these files will be instrumented by Istanbul)
        '../app/app.js' : ['sourcemap', 'coverage' ],

    },
    reporters: ['progress', 'coverage'],

    // web server port
    port: 9876,

    coverageReporter: {
          type : 'html',
          dir : 'coverage/'
      },
    // and some other stuff
  });
};

目前我的覆盖率报告提供了足够的指标，但与单个打字稿文件无关，而是 app.js。

我想我要么搞砸了预处理器配置，要么我需要指定源映射。

有什么提示吗？

使用 karma-istanbul-remap 对我有用。

karma.conf.js：

module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],
    plugins: [
          'karma-jasmine',
          'karma-ng-html2js-preprocessor',
          'karma-coverage',
          'karma-phantomjs-launcher',
          'karma-remap-istanbul'

      ],
    preprocessors: {
        '../app/directives/controls/**/*Template.html' : [ 'ng-html2js' ],

            // source files, that you wanna generate coverage for
            // do not include tests or libraries
            // (these files will be instrumented by Istanbul)
        '../app/app.js' : ['coverage' ],

    },
    reporters: ['progress', 'coverage', 'karma-remap-istanbul'],

    // web server port
    port: 9876,

    coverageReporter: {
        type : 'json',
        subdir : '.',
        dir : 'coverage/',
        file : 'coverage.json'
    },
    remapIstanbulReporter: {
          src: 'coverage/coverage.json',
          reports: {
              lcovonly: 'coverage/lcov.info',
              html: 'coverage/html/report'
          },
          timeoutNotCreated: 5000, // default value
          timeoutNoMoreFiles: 1000 // default value
    },
    // and some other stuff
  });
};
