Unit testing Karma测试失败，浏览器断开连接错误，退出代码：1

我们总共有2016个用Jasmine编写的单元测试用例，并且正在使用Karma来运行它们。测试运行1分钟30秒到2分钟，然后Karma突然与浏览器断开连接。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。我尝试了不同的Karma记者，以便能够识别迫使它与浏览器断开连接的测试用例，但到目前为止都没有成功

我也尝试过在短批中运行测试，以便能够深入到错误测试用例（如果是测试用例错误而不是Karma配置），但到目前为止，所有批都抛出了错误

根据帖子，我尝试将

browserNoActivityTimeout

设置为高达10分钟（600000毫秒），但仍然没有分辨率。此外，文章还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（两者都是Windows 10）中运行这些案例

以下是完整的堆栈跟踪：
