如何获得挂起 Ruby 进程的回溯？

Question

有一个包含 Capybara、Selenium、Allure 的复杂测试套件，但都被滥用了：

• 它会自行启动和退出 Chrome，而不是将这项工作留给 Capybara
• 之前和之后的钩子放错了地方，造成的影响，例如，当你这样做时会填充远程数据库rspec --dry-run
• Allure 报告 gem 几乎被遗弃了，我相信这里的集成也并非没有错误做法

现在当我运行测试时，它们有时会挂起，所以我按 ^C 但它们不会停止：

RSpec is shutting down and will print the summary report... Interrupt again to force quit.

无论我等待多长时间，甚至手动关闭浏览器，它都不会停止。

当我再次按^C 时，它什么也没有打印——没有回溯。
我怎么知道它挂在哪里？我如何随时获得它的回溯？

Answer 1

输出Ruby相关进程。

终止 Rspec 进程。
