【问题描述】：
我加入了一个开发团队，我有一个项目在 ruby (2.6.5) on rails (6) 上，我们正在向其中添加测试以增加 simplecov 的覆盖率。问题是从 Mac CatalinaOS 环境转移到 Ubuntu。
我们使用 asdf 版本管理器我们在本地安装了所有依赖项，数据库也安装了，redis 和 sidekiq 相同。项目可以执行；但是，当想要使用 bundle exec rake test 运行测试时，Ubuntu 在运行一些测试后会卡住。
我们通过卸载 ruby、node 和 yarn 版本进行了测试。重新安装所有内容，甚至重新安装 PopOS 19.10，问题仍然存在。有谁知道为什么 ruby 在这些条件下会在 Ubuntu 中挂起？？
我在 CTRL+C 之后添加堆栈跟踪，进程挂起超过 20 分钟。

【问题讨论】：
-
您使用的是什么测试套件？当它“卡住”时，它总是相同的规格吗？在此之前运行多长时间？你能发布你的规范助手/配置吗？您是否能够在不挂起的情况下运行特定的测试文件？您使用什么宝石进行测试？它可以是任何东西，如果没有细节，我们只能在黑暗中拍摄。
-
我使用 minitest、capybara 和 simplecov。当它卡住时，它并不总是在同一个测试中。多长时间是可变的，有时它只运行 5 次测试，但有时运行 100 次。我不能从项目中发布任何文件，因为它是私有的并且归第三方所有。我很确定它不需要对 gem 做任何事情，因为 mac 环境使用的是相同的 gem。甚至 ubuntu 笔记本电脑的所有规格都更高，例如它有一个 ssd，而 mac 仍在使用 hdd。它与ubuntu有关。
-
你在使用 docker 吗？您能否构建一个容器化应用程序来查看问题是否仍然存在？
-
我已经在 Docker、Ubuntu base 和 alpine 中运行过它，但问题并没有持续存在，这就是为什么我认为是关于 Distro 的原因
-
你检查
log/test.log了吗？您是否每次都卡在特定的测试中？比如在调用外部API的测试中，你正在使用的PC的IP发生变化，丢包？
