How to test Procedural code using "PHPUnit" Framework?

[dhillarun]

Hi All,

I have written some PHPUnit test code by using classes.
test.php

 
<?php
require_once('PHPUnit/Framework.php');
include("hello.php");
 class Test1 extends  PHPUnit_Framework_TestCase
 {
 
        function testAdd() {
            $a=3;
            $b=6;
             $r=add($a,$b);
            $this->assertNotNull($r);
            $this->assertEquals($r,9);
            $this->assertTrue($r>0);
        }
}
?>
 

hello.php

 
<?php
  function add($a,$b)
 {
      return ($a+$b);
}
?>
 

Here I am able to test whether the function is returning the expected value for the given input paramaters or not.

But, How to test the code inside the function "add()".

I mean, the testing should be done to the php code (for example:- for loops, if conditions etc.) present inside the "add()" function body.

Pl. do reply me.
