Ruby Pry 定位触发 pry 的测试文件

Question

我有一段代码通过集成测试触发我的 pry 会话，但不存在单元测试。因此，我不确定哪个测试正在执行此代码，并且每次我希望它触发时都需要运行所有测试。有没有办法在撬会话中冒泡测试/测试文件？我不需要触发 pry 会话的 _file_。

我最好的解决方案是在 pry 会话中引发错误，然后继续测试套件，希望这会弄错测试并能够在测试报告中找到该测试。这种做法有点像在黑暗中刺伤。

您应该能够通过简单地调用 caller 来获得完整的调用堆栈：

$ pry
[1] pry(main)> caller
=> ["/home/john/.gem/ruby/2.7.0/gems/pry-0.13.1/lib/pry/pry_instance.rb:290:in `eval'",
 "/home/john/.gem/ruby/2.7.0/gems/pry-0.13.1/lib/pry/pry_instance.rb:290:in `evaluate_ruby'",
