WrapIO

Allows the faking of input to STDIN and capturing of output from STDOUT with semantic method names. Great for testing!

Installation

Add this line to your application's Gemfile:

gem 'wrapio'

And then execute:

$ bundle

Or install it yourself as:

$ gem install wrapio

Usage

WrapIO

Captures output from STDOUT

# wrapio_test.rb

output = WrapIO.of do
	puts "Hello World!"
end

puts output
$ ruby wrapio_test.rb

"Hello World!"

Enable debug to see the faked STDIN

# wrapio_test.rb

WrapIO.debug = true
output = WrapIO.of('input') do
	gets
	puts 'output'
end
$ ruby wrapio_test.rb

-- WrapIO Capture#output  --
-- WrapIO Fake#gets 1 --
input
________________________
output

____________________________

Or use the internal module classes separately

WrapIO::Fake

# fake_test.rb

WrapIO::Fake.input('Hello!') do
	input = gets
end
puts input
$ ruby fake_test.rb

"Hello!"

WrapIO::Capture

# capture_test.rb

output = WrapIO::Capture.output do
	print "Hi!"
end
puts output
$ ruby capture_test.rb

"Hi!"

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
