+ 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.
