Karma-Jasmine测试执行错误HeadlessChrome

Question

我正在尝试测试我的图表组件，我收到以下错误：

  

HeadlessChrome 64.0.3240（Linux 0.0.0）ERROR已断开连接，因为   在60000毫秒内没有消息。 HeadlessChrome 64.0.3240（Linux 0.0.0）：   执行0 of 416 DISCONNECTED（1分0.007秒/ 0秒）   HeadlessChrome 64.0.3240（Linux 0.0.0）ERROR HeadlessChrome 64.0.3240   （Linux 0.0.0）：执行0 of 416 DISCONNECTED（1分0.007秒/ 0   秒）

我不知道问题所在。我做错了什么？

我在不同的其他组件中使用图表组件作为共享组件。
