ng 测试不起作用 业力无法启动“ChromeHeadless 在 2000 毫秒内没有被杀死，正在发送 SIGKILL。”

Question

I am not able to start angular tests due to unknown reasons. it says endlessly, "Chrome have not captured in 60000 ms, killing, ChromeHeadless was not killed by SIGKILL in 200ms, continuing".

I have no idea what is the problem? What is missing at my side? Attached is the screenshot for this.

Following is karma.conf.js

  //Karma configuration file, see link for more information
 //https://karma-runner.github.io/1.0/config/configuration-file.html

const { join } = require('path');
  const getBaseKarmaConfig = require('../../karma.conf');

  module.exports = function(config) {
     const baseConfig = getBaseKarmaConfig();
     config.set({
    ...baseConfig,
    coverageIstanbulReporter: {
      ...baseConfig.coverageIstanbulReporter,
      dir: join(__dirname, '../../coverage/apps/login/')
    }
  });
};

and complete karma.conf.js is :

    // Karma configuration file, see link for more information
// https://karma-runner.github.io/1.0/config/configuration-file.html

const { join } = require('path');
const { constants } = require('karma');

module.exports = () => {
    return {
        basePath: process.cwd() + '/apps/login',
        frameworks: ['jasmine', '@angular-devkit/build-angular'],
        plugins: [
            require('karma-jasmine'),

            require('karma-jasmine-html-reporter'),

            require('karma-spec-reporter'),
            require('@angular-devkit/build-angular/plugins/karma')
        ],
        proxies : {
            '/assets/': 'assets/'
        },
        client: {
            clearContext: false // leave Jasmine Spec Runner output visible in browser
        },
        coverageIstanbulReporter: {
            dir: join(__dirname, '../../coverage'),
            reports: ['html', 'lcovonly', 'text-summary'],

};

Are you using puppeteer to install ChromeHeadless? Try specifying the path to the executable and see if that gets ChromeHeadless to launch properly.

Here is a sample karma.conf.js:

module.exports = function (config) {
  const puppeteer = require('puppeteer');
  process.env.CHROME_BIN = puppeteer.executablePath();

  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    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')
    ],
    client: {
      clearContext: false // leave Jasmine Spec Runner output visible in browser
    },
    coverageIstanbulReporter: {
      reports: ['html', 'lcovonly', 'text-summary'],
      fixWebpackSourcePaths: true
    },
    reporters: ['progress', 'kjhtml'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome', 'ChromeHeadless'],
    singleRun: true,
    restartOnFileChange: true
  });
};
