ArchFizzBuzz

An example of using Behavior-Driven Development and (very basic) Domain Driven Design for creating a FizzBuzz library and command-line utility using Behat 3 for functional testing and PhpSpec 2 for unit testing / specing.

Install

$ git clone https://github.com/archfizz/archfizzbuzz
$ cd archfizzbuzz
$ composer install # requires Composer to be installed globally

Usage

To print the sequence for 100 steps for example, run:

$ ./fizzbuzz 100      # returns 1, 2, Fizz, 4, Buzz, Fizz, 7, 8...

If no number is provided, it will default to 15 steps.

Run Unit Tests/Specifications with PhpSpec

$ bin/phpspec run -fpretty

This specs can be found in the specs directory.

Run Integration/Functional Tests with Behat

$ bin/behat --format=pretty

The tests can be found in the features directory.

Feature: Generating the FizzBuzz sequence
  In order to teach about division (or BDD)
  As a teacher (or developer)
  I need to generate the sequence of the FizzBuzz game

Scenario: Printing the sequence from 1 to 32
  Given I am in the FizzBuzz app directory
   When I run "./fizzbuzz 32"
   Then it should print:
"""
1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, Buzz, 11, Fizz, 13, 14, FizzBuzz, 16, 17, Fizz, 19, Buzz, Fizz, 22, 23, Fizz, Buzz, 26, Fizz, 28, 29, FizzBuzz, 31, 32
