How can I unit test a Symfony2 controller?

Question

I want to use Test Driven Development as much as possible — it\'s a great way of working.

Use mocks to isolate models and other objects from main controller method's logic, see http://www.phpunit.de/manual/3.7/en/test-doubles.html#test-doubles.mock-objects

I think that in older versions you could mock entire class, but with latest phpunit 3.6.10 that i have it doesn't seem to work. So i guess you are left with depency injection pattern

class objss{
    function ss(){
        $x = new zz();
        var_dump($x->z());
    }
}



class MoTest extends PHPUnit_Framework_TestCase{
    public function setUp(){

    }

    public function testA(){
        $class = $this->getMock('zzMock', array('z'), array(), 'zz');
        $class->expects($this->any())->method('z')->will($this->returnValue('2'));

        $obj = new objss();
        $this->assertEquals('2', $obj->ss());
    }
}
