code_challenge_2018

This picks out randomized groups based on a list of entries and the number of entries per group.

It requires a CSV file containing entries, they can be multiple colums, however entries are comma separated.

#example test.csv
entry
john
jane
jack

#or test.csv
entry1,entry2
john,john
jack,jack
jane

It will return a CSV file titled results.csv, where each row is a group of randomized, deduped entries and each column is an entry.

#example results.csv
entry_1,entry_2
john,jack
jane

dependencies

This repo runs in Ruby, version 2.3.0. All dependencies are located in the Gemfile. In the command line, run:

$ bundle install

testing

Unit Tests for determining groups (picker.rb) are written using RSpec. To run all tests:

$ bundle exec rspec

To test the user interface, create a test CSV file:

$ ruby gen_test_file.rb

To optionally check for dedupe logic:

$ ruby gen_test_file.rb dup

Then run app.rb in your terminal:

$ ruby app.rb

filename containing names to group?
#enter name of source file

how many entries per group?
#enter number of entries

how to use

Run app.rb in terminal:

$ ruby app.rb

filename containing names to group?
#enter name of source CSV file

how many entries per group?
#enter number of entries

The app will print results to the screen and ask if you would like to regenerate those results (y/n).
