业力并行执行测试用例两次

Question

我正在将我的angular从4升级到版本7。我已经进行了业力并行运行tdd，并且它在Angular 4中可以按预期工作。现在，在升级到7之后，相同的测试运行两次，然后停止执行。我的karma.conf.js如下，

const path = require('path');
module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: [ 'parallel', 'jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-parallel'),
      require('karma-jasmine'),
      require('karma-spec-reporter'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-coverage-istanbul-reporter'),
      require('@angular-devkit/build-angular/plugins/karma')
    ],
    parallelOptions: {
      executors: 3, // For Jenkins enterprise, stick to 6 executors. For local laptop, change to 3-5
      shardStrategy: 'round-robin'
    },
    client: {
      jasmine: {
        random: false
      },
      clearContext: false
    },
    coverageIstanbulReporter: {
      reports: ['html', 'json', 'text-summary'],
      dir: path.join(__dirname, 'coverage'),
      fixWebpackSourcePaths: true
    },    
    reporters: ['spec', 'kjhtml'],
    specReporter: {
         maxLogLines: 5,
         suppressErrorSummary: true,
         suppressFailed: false,
         suppressPassed: false,
         suppressSkipped: true,
         showSpecTiming: true,
         failFast: false
      },
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['ChromeHeadlessNoSandbox'],
    customLaunchers: {
        ChromeHeadlessNoSandbox: {
            base: 'ChromeHeadless',
            flags: [
                '--no-sandbox', // required to run without privileges in docker
                '--user-data-dir=/tmp/chrome-test-profile',
                '--disable-web-security',
                '--no-proxy=http://0.0.0.0:9876/'
            ]
        }
    },
    singleRun: true,
    concurrency: Infinity,
    captureTimeout: 180000,
    browserDisconnectTimeout: 90000,
    browserNoActivityTimeout: 180000
  });
};

用于运行测试用例的命令如下，

node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng test --watch=false --code-coverage --source-map=false

请咨询。

所以我找到了问题。在angular.json文件中，我有2个项目都配置了测试块，这导致它运行两次。删除最后一个项目测试块即可解决。
