使用 karma 运行测试时出现间歇性断开消息错误

如何解决使用 karma 运行测试时出现间歇性断开消息错误

我正在使用 karma 和 jasmine 运行角度测试，最初在日志中我得到这些行

中间的某个地方我得到了这个

build   19-Jun-2021 06:47:01         [exec] [36m19 06 2021 13:47:01.322:DEBUG [HeadlessChrome 72.0.3617 (Windows 10.0.0)]: [39mNew connection /#UZNKm8o6mz9HgVItAAAB (already have /#TqAbgSkB7WclfRg0AAAA)

最终测试用例失败，此日志

我已经尝试通过添加 captureTImeout 和 browserNoActivityTimeout 仍然行为相同。

谁能帮我解决这个问题。提前致谢。
