During a job-interview I was asked to solve this programming exercise:

Code Kata Oktoberfest

Introduction

Bill and Bob attend the Oktoberfest. They are ordering every hour one Mass beer (14.95CHF). Each round they toast themselves:“Prost!”.

My PHP Solution

Let’s write a test first:

<?php

class ParticipantTest extends PHPUnit\Framework\TestCase
{
    public static function setUpBeforeClass() : void {
        require_once 'participant.php';
    }

    public function setUp() : void {
        $this->bob        = new Participant('Bob');
        $this->beer_price = 1495;
    }

    public function testGetDuration() : void {
        $this->assertEquals(3.5, $this->bob->duration);
    }

    public function testGreeting() : void {
        $this->assertEquals("Prost!", $this->bob->toast());
    }

    public function testGetTotalCost() : void {
        $this->assertEquals(0, $this->bob->getTotalCost());
        $this->bob->order();
        $this->assertEquals($this->beer_price, $this->bob->getTotalCost());
        $this->bob->order();
        $this->assertEquals(($this->beer_price * 2), $this->bob->getTotalCost());
    }

    public function testGetTotalConsumption() : void {
        $this->assertEquals(0, $this->bob->getTotalConsumption());
        $this->bob->order();
        $this->assertEquals(1, $this->bob->getTotalConsumption());
        $this->bob->order();
        $this->assertEquals(2, $this->bob->getTotalConsumption());
    }
}

Running the tests:

1. Install RSpec:
2. Execute the tests:

My Python Solution

# oktoberfest_test.python

import unittest

from hello_world import hello

class HelloWorldTest(unittest.TestCase):
    def test_say_hi(self):
        self.assertEqual(hello(), "Hello, World!")


if __name__ == "__main__":
    unittest.main()

Running the tests:

python oktoberfest.py
