<?php
/*
Test-Simple-OO.php:
A workalike of Perl's Test::Simple for PHP.
Why Test-Simple?
Test-Simple is a super simple way to start testing RIGHT NOW.
Why ok and not ok?
Test-Simple produces TAP compliant output.
For more on TAP, see: http://testanything.org
For the TAP spec, see: http://search.cpan.org/dist/TAP/TAP.pm
Why plan?
Planning is enforced because, unless you explicitly declare your
intent, the test set cannot ensure that all the required testing
was performed. An assumption could be made, but error prone
assumptions are exactly what testing is here to prevent.
Other testing libraries:
You can replace Test-Simple with Test-More without making any changes
to existing test code, providing access to further testing methods.
You can also replace any other PHP Test::More workalike library out there
with Test-More.php and it will work without making any changes to the code.
Assertions:
produce TAP output
provide basic testing functions (plan, ok)
exit with error code:
0 all tests successful
255 test died or all passed but wrong # of tests run
any other number how many failed (including missing or extras)
Example:
require_once('Test-More-OO.php');
$t = new TestMore();
$t->plan(2);
$t->ok(1 + 1 = 2, 'One plus one equals two');
$t->ok( doSomethingAndReturnTrue() , 'doSomethingAndReturnTrue() successful');
Procedural Example:
require_once('Test-Simple');
plan(2);
ok(1 + 1 = 2, 'One plus one equals two');
ok( doSomethingAndReturnTrue() , 'doSomethingAndReturnTrue() successful');
From a browser
If you are running Test-Simple on a web server and want slightly more web-readable
output, call the web_output() method/function.
Updates
Updates will be posted to the Google code page:
http://code.google.com/p/test-more-php/
Bugs
Please file bug reports via the Issues tracker at the google code page.
