Useful code for file-based Unit Test in PHP

You may need some kind of unit testing when you develop a project composed of multiple PHP files.

Below code block is what I am using for unit testing

if (is_array($argv) && ($argv[0]==basename(__FILE__))) foreach($argv as $v) if ($v=="-d")
{

	// write your test code here

	


	echo <<< CLI_MESSAGE
	===================
	TEST COMPLETED !
	\n\n
	CLI_MESSAGE;
	
}

You can test your code as following on the command line:

php <your filename> -d

Below is the class template I use

global $ck;
$__class_obj_name = pathinfo(__FILE__)['filename'];
if (@is_object($ck[ $__class_obj_name ]) == false)
{
	// beginning of class ------------------------------------------------------------------------------------------------------
	class TCKYOURCLASS
	{
		function __construct()
		{
		}
	};
	// end of class  ------------------------------------------------------------------------------------------------------

	if (!is_array($ck)) $ck=[];
	$ck[ $__class_obj_name ] = new TCKYOURCLASS;

	if (!function_exists( 'MYFUNCTION' ) )
	{
		function MYFUNCTION()
		{
		}
	}


	/*
		test code
		-----------

		php <YOURFILENAME> -d
	*/
	if (is_array($argv) && ($argv[0]==basename(__FILE__))) foreach($argv as $v) if ($v=="-d")
	{

		// write your test code here

		


		echo <<< CLI_MESSAGE
		===================
		TEST COMPLETED !
		\n\n
		CLI_MESSAGE;
		
	}

}

// removed end of PHP tag intentionally to avoid unintended CR+LF at the code

I hope this is helpful for you
