ng test --code-coverage

它在coverage文件夹中编写代码覆盖率报告.

我需要查看整个项目的覆盖范围,而不仅仅是有测试的文件.

karma.conf.js

module.exports = function (config) {
  config.set({
    basePath: '',frameworks: ['jasmine','angular-cli'],plugins: [
      require('karma-jasmine'),require('karma-jasmine-html-reporter'),require('karma-chrome-launcher'),require('karma-remap-istanbul'),require('angular-cli/plugins/karma'),require('karma-coverage'),require('karma-sourcemap-loader')

    ],files: [
      { pattern: './src/test.ts',watched: false }
    ],preprocessors: {
      './src/test.ts': ['angular-cli']
    },mime: {
      'text/x-typescript': ['ts','tsx']
    },remapIstanbulReporter: {
        reports: {
          html: 'coverage',lcovonly: './coverage/coverage.lcov'
      }
    },angularCli: {
      config: './angular-cli.json',environment: 'dev'
    },reporters: config.angularCli && config.angularCli.codeCoverage
              ? ['progress','karma-remap-istanbul']
              : ['progress','kjhtml'],coverageReporter: {
      includeAllSources: true
    },port: 9876,colors: true,logLevel: config.LOG_INFO,autoWatch: true,browsers: ['Chrome'],singleRun: false
  });
};
