Versions.

@angular/cli: 1.1.0

Repro steps.

Change the karma.conf.js file as follows :

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular/cli'],
    plugins: [
      require('karma-jasmine'),
      // require('karma-chrome-launcher'),
      require('karma-phantomjs-launcher'),
      require('karma-junit-reporter'),
      require('@angular/cli/plugins/karma')
    ],
    files: [
      { pattern: './src/test.ts', watched: false }
    ],
    preprocessors: {
      './src/test.ts': ['@angular/cli']
    },
    mime: {
      'text/x-typescript': ['ts', 'tsx']
    },
    junitReporter: {
      outputDir: 'coverage', // results will be saved as $outputDir/$browserName.xml
      useBrowserName: false, // add browser name to report and classes names
      outputFile: 'test-report.xml', // if included, results will be saved as $outputDir/$browserName/$outputFile
    },
    angularCli: {
      config: './angular-cli.json',
      environment: 'dev'
    },
    reporters: ['junit'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: [
      'PhantomJS',
      // 'Chrome'
    ],
    singleRun: false
  });
};

The log given by the failure.

$ npm run test -- --watch=false --code-coverage

      Perhaps you are missing some plugin?

Desired functionality.

I would like to change the reporter used for the code coverage, but coverage-istanbul is always used, even though I don’t have the package (I removed it from package.json and used npm prune)

Mention any other details that might be useful.

Thanks for the intel. But I still have one question remaining : what is the point of having those lines

reporters: config.angularCli && config.angularCli.codeCoverage ?
  ['mocha', 'junit'] :
  ['mocha'],

in the karma.conf.js, if they’re not used ?
