PHPUnit_TestMore
PHPUnit is a great unit testing framework for PHP http://www.phpunit.de/manual/current/en/.
This helper library PHPUnit_TestMore https://github.com/c9s/PHPUnit_TestMore is for PHPUnit Test Framework, which brings the good things from the Test::More http://search.cpan.org/~mschwern/Test-Simple-0.98/lib/Test/More.pm library of Perl into PHP platform.
The original PHPUnit TestCase is trivial, for example:
function test() {
$this->assertTrue( true );
$this->assertArrayHasKey('foo', array('bar' => 'baz'));
$this->assertClassHasAttribute('foo', 'stdClass');
$this->assertContains(4, array(1, 2, 3));
}
If you write Perl, you must be familiar with this:
#!/usr/bin/env perl
use Test::More tests => 10;
$val = 1;
ok( $val );
is( 1, 1 );
Which is much simpler and easy, let you not to hate writing unit tests.
Then here is the PHP version's Test::More:
class FooTest extends PHPUnit_Framework_TestCase
{
function test()
{
ok(1);
ok(true);
ok('string');
not_ok(false);
}
}
Setup phpunit.xml configuration
Create a file named phpunit.xml, and set the attribute printerClass to PHPUnit_Util_Log_TAP:
<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="tests/bootstrap.php"
backupGlobals="false"
verbose="true"
syntaxCheck="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
printerClass="PHPUnit_Util_Log_TAP">
<testsuites>
<testsuite name="PHPUnit">
<directory suffix="Test.php">tests</directory>
</testsuite>
</testsuites>
</phpunit>
In your bootstrap.php, require the TestMore helper.
require 'tests/PHPUnit_TestMore.php';
How it works
To reduce unit testing code, there is a function called debug_backtrace, which returns a call stack of current function call.
Here is some ideal PHP code synopsis for testing:
function test()
{
ok( 1 );
is( 1, 1);
}
To let the ok function get the caller object, we use debug_backtrace to call the original assertNotEmpty method:
function ok( $v , $msg = null )
{
$stacks = debug_backtrace( DEBUG_BACKTRACE_PROVIDE_OBJECT ); $testobj = $stacks[1]['object'];
$testobj->assertTrue( $v ? true : false , $msg );
}
