PhpUnit::How can be __construct with protected variables tested?
(not always we should add public method getVal()- soo without add method that return protected variable value)
Example:
class Example{
protected $_val=null;
function __construct($val){
$this->_val=md5 ($val);
}
}
Edit:
also exist problem to test in function that return void
Edit2:
Example why we need test __construct:
class Example{
protected $_val=null;
//user write _constract instead __construct
function _constract($val){
$this->_val=md5 ($val);
}
function getLen($value){
return strlen($value);
}
}
class ExampleTest extends PHPUnit_Framework_TestCase{
test_getLen(){
$ob=new Example();//call to __construct and not to _constract
$this->assertEquals( $ob->getLen('1234'), 4);
}
}
test run ok, but Example class "constructor" wasn't created!
Thanks
