je postup jak v phpunit mockovat běžné metody. Zná někdo chodivý způsob jak podobně mockovat magickou metodu __get? Zatím jsem dospěl k tomu, že problém je s vícenásobným voláním funkce __get s různými parametry. Uvádim příklad srovnávající běžnou a magickou metodu:

<?php
require_once 'PHPUnit/Framework.php';

class myClass
{
    public function normalMethod() {
        return 'normal';
    }
    public function normalMethod2() {
        return 'normal2';
    }
    public function __get($name) {
        switch($name){
            case 'propertyA':
                return 'AAA';
            case 'propertyB':
                return 'BBB';
        }
    }
}

class testedClass
{
    public function testedMethodNormal(myClass $obj) {
        // tady se bude nejak pracovat s metodami objektu $obj
        return $obj->normalMethod() == 'fake' && $obj->normalMethod2() == 'fake2';
    }
    public function testedMethodMagic(myClass $obj) {
        // tady se bude nejak pracovat s vlastnostmi objektu $obj
        return $obj->propertyA == 'fakeA' && $obj->propertyB == 'fakeB';
    }
}

class testedClassTest extends PHPUnit_Framework_TestCase
{
    public function testNormal() {
        $mock = $this->getMock('myClass');
        $mock->expects($this->any())
             ->method('normalMethod')
             ->will($this->returnValue('fake'));
        $mock->expects($this->any())
             ->method('normalMethod2')
             ->will($this->returnValue('fake2'));
        $this->assertEquals('fake', $mock->normalMethod()); // OK
        $this->assertEquals('fake2', $mock->normalMethod2()); // OK
        $tested = new testedClass();
        $this->assertTrue($tested->testedMethodNormal($mock)); // OK
    }

    public function testMagic() {
        $mock = $this->getMock('myClass');
        $mock->expects($this->any())
             ->method('__get')
             ->with($this->equalTo('propertyA'))
             ->will($this->returnValue('fakeA'));
        $this->assertEquals('fakeA', $mock->propertyA); // OK
        $mock->expects($this->any())
             ->method('__get')
             ->with($this->equalTo('propertyB'))
             ->will($this->returnValue('fakeB'));
        $this->assertEquals('fakeB', $mock->propertyB); // fail
    }

    public function testMagic2() {
        $mock = $this->getMock('myClass');
        $mock->expects($this->any())
             ->method('__get')
             ->with($this->equalTo('propertyA'))
             ->will($this->returnValue('fakeA'));
        $this->assertEquals('fakeA', $mock->propertyA); // OK
        $mock = $this->getMock('myClass');
        $mock->expects($this->any())
             ->method('__get')
             ->with($this->equalTo('propertyB'))
             ->will($this->returnValue('fakeB'));
        $this->assertEquals('fakeB', $mock->propertyB); // OK
        // tohle reseni nevyhovuje, protoze mockovany objekt se predava do
        // testovane metody a je potreba mockovat vice vlastnosti
        $tested = new testedClass();
        $this->assertTrue($tested->testedMethodMagic($mock)); // fail
    }

    public function testMagic3() {
        $mock = $this->getMock(
            'myClass',
            array('_get'),
            array('propertyA', 'propertyB'),
            '',
            false
        );
        $mock->expects($this->any())
             ->method('__get')
             ->with($this->equalTo('propertyA'))
             ->will($this->returnValue('fakeA'));
        $this->assertEquals('fakeA', $mock->propertyA); // fail
        $mock->expects($this->any())
             ->method('__get')
             ->with($this->equalTo('propertyB'))
             ->will($this->returnValue('fakeB'));
        $this->assertEquals('fakeB', $mock->propertyB); // fail
    }
