因果并行npm软件包不适用于圈子CI

Question

我正在使用karma-parallel npm软件包在有角度的应用程序上运行karma单元测试。在我的本地计算机上，它像一个魅力一样工作，并大大减少了构建时间。但是，当我在Circle CI上运行时，单元测试用例似乎失败了。

我仍在寻找Circle CI是否支持业力平行度，但是我还没有发现任何东西

My Karma.conf.js file looks like this:

    module.exports = function (config) {
       config.set({
          basePath: '',
          frameworks: ['parallel', 'jasmine', '@angular-devkit/build-angular'],
          plugins: [
             require('karma-parallel'),
             require('karma-jasmine'),
             require('karma-chrome-launcher'),
             require('karma-spec-reporter'),
             require('karma-jasmine-html-reporter'),
             require('karma-coverage-istanbul-reporter'),
             require('@angular-devkit/build-angular/plugins/karma')
          ],
          parallelOptions: {
             executors: 2,
             shardStrategy: 'round-robin' 

         })};

Expected Behavior: The unit tests should run in parallel on the circle CI as they do on my local machine.

Actual Behavior: The unit test fails on the circle CI and I get the following error:
