I assume this is very newbie stuff but I'm learning Ruby by doing, and I'm developing a small CLI tool that receives a couple of parameters in order to do its stuff properly. This is my current workflow:
I want to test (using Minitest) all the possible flows:
Now, if I run tests the only thing I see is the help output as there is no parameter being passed.
So, a couple of questions:
puts

nice diagram!
you can either use helpers like aruba https://github.com/cucumber/aruba
or dig into ruby internals in order to bend it to your will!
# test.rb
pseudoIO = StringIO.new
$stdout = pseudoIO
puts "hi #{ARGV.join(', ')}"
ARGV.replace ["file1"]
puts "now its #{ARGV.join(', ')}"
abort "captured: #{pseudoIO.string}"
output should be
ruby text.rb "whutup"
# => captured: hi whutup
# => now its file1
