Example mocking Mage getControllerInstance

Mocking - Mage::getControllerInstance()

Code you want to test

<?php
class MyCompany_MyModule_Model_Example_Mocking
{
    public function doSomething()
    {
        /** @var MyCompany_MyModule_Index_IndexController $indexController */
        $indexController = Mage::getControllerInstance('mycompany_mymodule/index_index')
        return $indexController;
    }
}

Test implementation

<?php
class MyCompany_MyModule_Unit_Model_Example_MockingTest
    extends TechDivision_MagentoUnitTesting_TestCase_Model
{
    /**
     * @var string
     */
    protected $_testClassName = 'MyCompany_MyModule_Model_Example_Mocking';

    /**
     * @var MyCompany_MyModule_Model_Example_Mocking
     */
    protected $_instance;

    public function testDoSomething()
    {
        // Build a mock object and register it for the
        // Mage::getControllerInstance() method with the correct key
        $controller = $this->buildMock('MyCompany_MyModule_Index_IndexController');
        $this->addMageControllerInstance('mycompany_mymodule/index_index', $controller);

        $result = $this->_instance->doSomething();
        $this->assertSame($controller, $result);
    }
}
