我正在将我的 angular 从 4 升级到版本 7。我有 karma-parallel 来运行 tdd，它在 Angular 4 中按预期工作。现在升级到 7 后，相同的测试在停止执行之前运行了两次。我的 karma.conf.js 如下，

    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'], …
