这是我的自定义格式化程序：
require 'pp'
require 'ap'
require "rspec/core/formatters/base_text_formatter"
def example_passed(example)
super(example)
output.print success_color('.')
ap example
end
def example_pending(example)
super(example)
output.print pending_color('*')
end
def example_failed(example)
super(example)
output.print failure_color('F')
end
def dump_summary(duration, example_count, failure_count, pending_count)
output.print 'Yep, everything\'s all finished'
end
end
我正在创建自己的rspec格式化程序，example哈希中有很多非常有用的数据。
查看我将example_passed方法打印到屏幕上的方法。然而，这将它打印成一个巨大的，无懈可击的文本墙，这使得编写代码来访问这些值几乎是不可能的。
我需要pp，并尝试pp example。什么都不做，巨大的文字墙。
我已安装并需要ap（awesome_print）并尝试ap example。仍然坚持着这一巨大的文字墙。
我没有收到任何错误消息，说明不能要求任何一个库。这与example的复杂性有关吗？它在某种程度上不仅仅是一个多维哈希吗？
这是庞然大物本身：
