Angularjs 如何从我的业力日志中删除HeadlessChrome日志消息

我正在运行Angular应用程序，我的单元测试按预期运行，但每次运行测试时都会收到以下警告：

HeadlessChrome 0.0.0 (Mac OS X 10.12.6) LOG: '>>>>>>', '', 'Error: STACKTRACE TRACKING'

这也是我的业力配置：

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular/cli'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular/cli/plugins/karma')
    ],
    client:{
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      reports: [ 'html', 'lcovonly' ],
      fixWebpackSourcePaths: true
    },
    angularCli: {
      environment: 'dev'
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    browsers: ['ChromeHeadless'],
    concurrency: Infinity,
    files: [
      { pattern: 'node_modules/hammerjs/hammer.min.js', included: true, watched: false },
      { pattern: 'node_modules/hammerjs/hammer.min.js.map', included: false, watched: false },
      { pattern: 'node_modules/@angular/material/prebuilt-themes/indigo-pink.css', included: true, watched: true },
    ]
  });
};

我真的很想从我的终端上删除这些日志消息。

有什么想法吗？

当您运行karma测试时，您可以尝试从

polyfill.ts

中删除

长堆栈跟踪区.js

。

对于未来的读者，请将此添加到您的karma配置中：

        browserConsoleLogOptions: {
        level: 'warn',
        format: '%b %T: %m',
        terminal: false
    },

我得到了同样的东西，只有我的开始：Chrome61.0.3163（MacOSX10.12.6）LOG:“…”我的测试失败了。
