Very simple SimpleTest drupal example

It was done to check basics of drupal SimpleTest work.
Module part just created a menu page with some "Hello World" text.
Test should check:

1. If drupal slice generated by SimpleText exists
2. If menu page exists
3. If menu page has a string "Lets test it!"

Module code:

1:  <?php  

2:    

3:  function alternative_example_menu() {  

4:   $items['alt_example'] = array(   

5:    'title' => 'Hello World test example',  

6:    'description' => 'Its easy and fun',  

7:        'page callback' => '_alt_example_basic_instructions',  

8:    'page arguments' => array(t('Hello World')),   

9:    'access callback' => TRUE,  

10:    'type' => MENU_NORMAL_ITEM,  

11:   );  

12:   return $items;  

13:   }  

14:     

15:   function _alt_example_basic_instructions($content = NULL) {  

16:   $base_content = t('Lets test it!');  

17:   return '<div>' . $base_content . '</div><br />';  

18:  }  

Test code:

1:  <?php  

2:    

3:  /**  

4:   * @file  

5:   * Tests for alternative example module.  

6:   */  

7:  class AlternativeExampleTestCase extends DrupalWebTestCase {  

8:   protected $custom_user;  

9:    

10:   public static function getInfo() {  

11:    return array(  

12:     'name' => 'Hello world example functionality',  

13:     'description' => 'Checks "Hello world" string and page',  

14:     'group' => 'Alternative Examples',  

15:    );  

16:   }  

17:    

18:   /**  

19:    * Enable modules and create user with specific permissions.  

20:    */  

21:   public function setUp() {  

22:    parent::setUp('alternative_example');  

23:   }  

24:   function testAlternativeHelloExample() {  

25:        // Load site  

26:    $this->drupalGet('');  

27:    // Load page  

28:    $this->clickLink(t('Hello World test example'));  

29:    // Look for string  

30:    $this->assertText(t('Lets test it!'));  

31:   }  

32:   }

Also there is possible to run SimpleTest through drush:

Nothing enormous. Tests should run faster if they will done like unit tests way but i should check that option next time.

array_rand function alternative

Strange thing happened with array_rand function after PHP 5.2.10 Release... I should paste it from official site:

"The resulting array of keys is no longer shuffled." 

C'mon i dont even understand now how it works. Anyway some good man make good and also elegant alternative, when you need to shuffle an array and take some entries from it.

 <?php  
 function array_random($arr, $num = 1) {  
   shuffle($arr);  
     
   $r = array();  
   for ($i = 0; $i < $num; $i++) {  
     $r[] = $arr[$i];  
   }  
   return $num == 1 ? $r[0] : $r;  
 }  
   
 $a = array("apple", "banana", "cherry");  
 print_r(array_random($a));  
 print_r(array_random($a, 2));  
 ?>
