MockStdio

Helpers for working with stdin and stdout in tests

Installation

Add this line to your application's Gemfile:

gem "mock_stdio"

And then execute:

$ bundle

Or install it yourself as:

$ gem install mock_stdio

Usage

Include in your spec helpers

require "mock_stdio"

RSpec.configure do |config|
  config.include MockStdio
end

Supply input to gets or any read from the stdio buffer and return anything written to stdout:

follow_prompts "Yes", "No", "Maybe" do
  puts "Should I?"
  gets
  puts "Really?"
  gets
  puts "Are you sure?"
  gets
end

Capture and return stdout:

capture_stdout { puts "Hey" }

Silence stdout to keep spec output clean:

config.before(:all, &:silence_output)
config.after(:all, &:enable_output)
