Unit Testing a PHP Script -


i have php scripts run cronjobs. no classes , few functions.

id test script phpunit make sure working appears need rewrite php class, dont want (or know how to).

for example if had script , function add 1 , 2 together, 

 <?php   $a=1;  $b=2  $c=$a+$b;   ?>

how test $c==3 phpunit?

thanks, don

for example, don't test $c = 3.

but because example little simplistic. variable $c stops existing after script executes. fact exists doesn't matter. want test code does, not how things.

i modify example little bit:

job.php

<?php  $a=1; $b=2 echo $a + $b;  ?>

now have output , behavior. test like:

public function testjob() {    require('job.php');    $this->expectoutputstring('3'); }

phpunit has ability assert against stdout. make sure code outputs expect. tests these types of files check did correct. since php's require statement execute file @ point, can run script , check output.

if file has functions, include , check each function in own individual test.
