Thank you to everyone who attended my May 25th PHP|Tek talk on Test Driven Development. If you have not had a chance, please do leave feedback on joind.in.

Per the audiance request, below are the requirements, test file and source code we developed during the live tutorial.

Requirements:
Hash object
get and set function
respond to array access

Tests:

<?php

require 'simpletest/autorun.php';
require 'hash.php';

class TekTDDUnitTestCase extends UnitTestCase {
    protected $subject;
    function setup() {
        $this->subject = new Hash;
    }

    function testClassExists() {
        $this->assertTrue(class_exists('Hash'),'Hash Class does not exist');
    }

    function testSetMethod() {
            $this->assertNull($this->subject->set('key','value'));
    }
    function testGetMethod() {
            $key = 'foo';
            $value = 'bar'.rand(0,100);

            $this->subject->set($key,$value);
            $this->assertEqual     ($value, $this->subject->get($key));
    }
    function testAccessAsAnArray() {
            $key = 'foo';
            $value = 'bar'.rand(0,100);

            $this->subject[$key] =$value;
            $this->assertEqual($value, $this->subject[$key]);

    }
}

?>

hash.php

<?php

class Hash implements ArrayAccess {
    protected $store = array();
    function offsetExists($key) {
    }
    function offsetGet($key) {
        return $this->get($key);
    }
    function offsetSet($key,$value) {
        $this->set($key, $value);
    }
    function offsetUnset($key) {
    }
    function set($key, $value) {
        $this->store[$key] = $value;
    }
    function get($key) {
        return $this->store[$key];
    }
}

?>
