  1. test: use IO#popen instead of Kernel#open 

    open("|command") spawns command and create pipes for
processing pipeline.

This feature of Kernel#open is deprecated, replace it with
IO#popen.

It fixes the following warning:

  warning: Calling Kernel#open with a leading '|' is deprecated and will
  be removed in Ruby 4.0; use IO.popen instead
