A unit testing framework in a tweet.

sample.php

<?php
require_once 'TestFrameworkInATweet.php';
it("should sum two numbers", 1+1==2);
it("should display an X for a failing test", 1+1==3);
done();

TestFrameworkInATweet.php

<?php
function it($m,$p){echo ($p?'✔︎':'✘')." It $m\n"; if(!$p){$GLOBALS['f']=1;}}function done(){if(@$GLOBALS['f'])die(1);}

Now there's even more, added error file and line every failed test and short summary at shutdown:

<?php
function it($m,$p){echo"\e[3".($p?"2m✔︎":"1m✘")."\e[0m It $m\n";if(!$p){$GLOBALS['e']=1;$d=debug_backtrace()[0];echo"ERROR {$d['file']}@{$d['line']}\n";}}register_shutdown_function(function(){echo"\e[1;3".(($e=@$GLOBALS['e'])?"7;41mFAIL":"2mOK")."\e[0m\n";die($e);});

Failing example:

it('should pass', true);
it('should fail', false);
it('should also fail', false);

Results:

✔︎ It should pass
✘ It should fail
ERROR /home/brzuchal/test-oneliner.php@6
✘ It should also fail
ERROR /home/brzuchal/test-oneliner.php@7
FAIL

Passing example:

it('should pass', true);

Results:

✔︎ It should pass
OK

And here is a link to my fork of this gist https://gist.github.com/brzuchal/5aeec672207bc9df4898ba99d6f7b369#file-testframeworkinatweet-php

So if someone would wanan use it can just:

<?php
include 'https://gist.githubusercontent.com/brzuchal/5aeec672207bc9df4898ba99d6f7b369/raw/22ce43d813007323e7cf1cee6a101f1ce7674466/TestFrameworkInATweet.php'
it('should pass', true);
it('should fail', false);
it('should also fail', false);

nice one :)

I gave up to colors, but

• use standard output/error for the success/failure output
• add some mimimum formatting
• add possibility to pass a callback as predicate

<?php
function it($m,$p){ $d=debug_backtrace(0)[0];
 is_callable($p) and $p=$p();
 global $e;$e=$e||!$p;
 $o=($p?"✔":"✘")." It $m";
 fwrite($p?STDOUT:STDERR,$p?"$o\n":"$o FAIL: {$d['file']} #{$d['line']}\n");
}

register_shutdown_function(function(){global $e; $e and die(1);});

Example:

it('should display an X for a failing test.', 1+1===3);

it('should append to an ArrayIterator.', function() {
  $iterator = new ArrayIterator();
  $iterator->append('test');
  return count($iterator) === 1 && $iterator->current() === 'test';
});

it('should pass test for InvalidArgumentException exception.', function() {
  try {
    throw new InvalidArgumentException();
  } catch(InvalidArgumentException $e) {
    return true;
  }
});

with output:

✘ It should display an X for a failing test. FAIL: /path/to/file.php #11
✔ It should append to an ArrayIterator.
✔ It should pass test for InvalidArgumentException exception.
