GreenDay

Green Day creates workspaces and tests for Atcoder contests （日本語で解説した記事はこちら)

Add this line to your application's Gemfile:

gem 'green_day'

And then execute:

$ bundle

Or install it yourself as:

$ gem install green_day

login(this command stores your cookie as .cookie-store in current directory)

$ bundle exec green_day login

If you want to delete session, remove .cookie-store

This command creates directory and spec.

$ bundle exec green_day new <contest-name>

For example

$ bundle exec green_day new abc150

Example of output spec

RSpec.describe 'abc150/A.rb' do
  it 'test with "2 900\n"' do
    if ENV['GD_REPL']
      File.chmod(0o755, 'abc150/A.rb')
      system(%q(expect -c 'set timeout 2; spawn ruby abc150/A.rb; send "2 900\n\\004"; interact'))
    else
      io = IO.popen('ruby abc150/A.rb', 'w+')
      io.puts("2 900\n")
      io.close_write
      expect(io.readlines.join).to eq("Yes\n")
    end
  end

  it 'test with "1 501\n"' do
    if ENV['GD_REPL']
      File.chmod(0o755, 'abc150/A.rb')
      system(%q(expect -c 'set timeout 2; spawn ruby abc150/A.rb; send "1 501\n\\004"; interact'))
    else
      io = IO.popen('ruby abc150/A.rb', 'w+')
      io.puts("1 501\n")
      io.close_write
      expect(io.readlines.join).to eq("No\n")
    end
  end

  it 'test with "4 2000\n"' do
    if ENV['GD_REPL']
      File.chmod(0o755, 'abc150/A.rb')
      system(%q(expect -c 'set timeout 2; spawn ruby abc150/A.rb; send "4 2000\n\\004"; interact'))
    else
      io = IO.popen('ruby abc150/A.rb', 'w+')
      io.puts("4 2000\n")
      io.close_write
      expect(io.readlines.join).to eq("Yes\n")
    end
  end

end

You can debug your code with sample input and REPL by setting GD_REPL environment variable.

$ GD_REPL=1 bundle exec rspec abc150/spec/A_spec.rb

abc150/A.rb
spawn ruby abc150/A.rb
2 900

From: abc150/A.rb @ line 2 :

    1: a, b = gets.split.map(&:to_i)
 => 2: binding.irb
    3: puts "Yes"

irb(main):001:0> a
=> 2
