无法在 Windows 10 上运行角度规范测试

Question

I am trying to run unit tests for an angular component in a Windows machine. What I observe is that there are no test launches. There is no error trace on console either. Following is what I get:

>ng test my-component

0% compiling(node:6420) DeprecationWarning: Tapable.plugin is deprecated. Use new API on .hooks instead

29 07 2019 16:52:05.121:INFO [karma]: Karma v1.7.1 server started at http://0.0.0.0:9876/

29 07 2019 16:53:09.138:WARN [launcher]: Chrome was not killed by SIGKILL in 2000 ms, continuing.

How to get tests running?

Cannot tell, without looking into your configuration, however try following karma configuration, do npm install with including the dependencies, post this, remove any unnecessary dependencies for you like "puppeteer" etc

const puppeteer = require('puppeteer');
process.env.CHROME_BIN = puppeteer.executablePath();

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    files: [
      './assets/content-and-assets/mock-google-api.js'
    ],

    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma'),
      require('karma-junit-reporter')
    ],
    client: {
      jasmine: {
        random: false
      },
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      dir: require('path').join(__dirname, '../coverage'),
      reports: ['html', 'lcovonly', 'cobertura', 'text', 'text-summary'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml', 'junit'],
    junitReporter: {
      outputFile: '../../junitreport/credit-check-tests.xml'
    },
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    customLaunchers: {
      ChromeHeadless: {
        base: 'Chrome',
        flags: [
          '--headless',
          '--disable-gpu',
          '--no-sandbox',
          '--remote-debugging-port=9222',
        ]
      },
      Chrome1: {
        base: 'Chrome',
        flags: ['--disable-web-security',
          '--enable-gpu']
      },
      ChromeDebugging: {
        base: 'Chrome',
        flags: ['--remote-debugging-port=9333']
      },

    },
     browsers: ['ChromeDebugging'],
     singleRun: false
    //browsers: ['ChromeHeadless'],
    //singleRun: true
  });
};

Works for me in Win10 as per my requirement.

PS : You can run chrome in headless mode, toggle-comment last two lines.

EDIT

I assume you have already installed chrome browser in your machine.( suggested )

In case, you intent not to use browser you can go for PhantomJS, however that is not performance efficient.
