EcomDev_PHPUnit assert block property contains

Question

I am having a problem asserting that a blocks property contains an array key.

I have added a link to the my customer account area using the following XML:

<customer_account>
    <reference name="customer_account_navigation">
        <action method="addLink" translate="label" module="namespace_ordermigration">
            <name>migration</name>
            <path>migration/order/list/</path>
            <label>Migrated Orders</label>
        </action>
    </reference>
</customer_account>

That addLink method is called on the block Mage_Customer_Block_Account_Navigation which has a protected property $_links = array();

Here the closest I could get with a EcomDev_PHPUnit_Test_Case_Controller test:

public function testMyAccountButtonDefined()
{
    $this->dispatch('migration/order/list');

    $this->assertLayoutBlockPropertyEquals('customer_account_navigation', '_links', array('migration' => ''));
}

Which fails:

1) Namespace_OrderMigration_Test_Controller_OrderController::testMyAccountButtonDefined
Failed asserting that two arrays are equal.

+    'account' => Varien_Object Object (...)
+    'account_edit' => Varien_Object Object (...)
+    'address_book' => Varien_Object Object (...)
...

Does anybody know how I could get access to the property it is testing so I could do a simpler PHPUnit test with the results?

Another potential option is creating a new wrapper around the assertContains method of PHPUnit_Framework_Assert in EcomDev_PHPUnit_Test_Case_Controller called something like $this->assertLayoutBlockPropertyContains. This is quite a bit of work and it would probably be better spent exposing the response.

Answer 1

This is how I ended tested a blocks property contains the array key I defined in my layout.xml, a bit more of a direct route and only possible as the property is exposed in the block, so not a valid answer just a work around

public function testMyAccountButtonDefined()
{
    $this->dispatch('migration/order/list');

    /* @var $block Mage_Customer_Block_Account_Navigation */
    $block = $this->app()->getLayout()->getBlock('customer_account_navigation');

    $this->assertContains('migration', array_keys($block->getLinks()));
}
