Question

我们总共有2016年使用Jasmine编写的单元测试用例，并使用Karma来运行它们。测试运行时间为1分30秒到2分钟，然后突然Karma与浏览器断开连接。Here是控制台日志的屏幕截图。

问题是我无法诊断为什么会发生这种情况以及哪个测试用例导致它断开连接。我已经尝试了不同的Karma记者，以便能够识别测试用例，迫使它与浏览器断开连接，但到目前为止还没有成功。

我也尝试过短时间运行测试以便能够深入到错误测试用例（如果它是测试用例错误而不是Karma配置）但是到目前为止，所有批次都抛出了错误

根据this帖子，我尝试将browserNoActivityTimeout设置为高达10分钟（600000毫秒），但仍无法解决问题。此外，帖子提到可能存在内存不足的问题，因此我尝试在一个8GB RAM和一个16GB RAM系统中运行这些案例（两者都是Windows 10）。

这是完整的堆栈跟踪：

这是我的配置文件：

module.exports = function(config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine'],
    files: [

      },
    preprocessors: {
      'src/**/*.js':['coverage'],
      'src/**/*.html':['ng-html2js']
    },
    coverageReporter: {

      dir: 'qualityreports/testresults/unit/coverage/'
    },
    htmlReporter: {

  });
};

Here是一个类似的帖子，但它没有所有细节，因此张贴我的。任何帮助都将深表感谢。
