If you only need to extract those lines the most efficient solution is 
probably

fgrep TestPhase <your files>

If you want to do it in Ruby you can do

ruby -ne 'puts $_ if /TestPhase/' <your files>

If you need to further process those lines you can do

ARGF.each |line|
   if /TestPhase/ =~ line
     # ...
     puts line
   end
end

There are probably plenty other options.

Kind regards
