I have a plugin that plugs into the execute method of \Magento\Checkout\Controller\Cart\Index and redirects under some condition.


<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    <type name="Magento\Checkout\Controller\Cart\Index">
        <plugin sortOrder="1" name="do_stuff_with_cart" type="MyVendor\MyModule\Plugin\CartPlugin"/>

The Plugin itself:


namespace MyVendor\MyModule\Plugin;

use MyVendor\MyModule\Helper\Data;
use Magento\Framework\App\Action\Action;
use Magento\Framework\App\ActionFlag;
use Magento\Framework\App\Response\RedirectInterface;
use Magento\Framework\Controller\ResultFactory;
use Magento\Framework\Event\Observer;
use Magento\Framework\Message\ManagerInterface;
use Magento\Framework\Pricing\Render;

class CartPlugin
    protected Data $helper;
    protected RedirectInterface $redirect;
    protected ResultFactory $resultFactory;

    public function __construct(
        Data $helper,
        RedirectInterface $redirect,
        \Magento\Framework\Controller\ResultFactory $resultFactory
    ) {
        $this->helper = $helper;
        $this->resultFactory = $resultFactory;
        $this->redirect = $redirect;

    public function aroundExecute($subject, callable $proceed)
        if ($this->helper->isEnabled()) {
            $resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);

            return $resultRedirect;

        return $proceed();

When I access the /checkout/index/ route locally in my dev environment, everything works as expected. However, this integration test fails:


namespace MyVendor\MyModule\Test\Integration;

use Magento\TestFramework\TestCase\AbstractController;

class FormTest extends AbstractController
     * @magentoConfigFixture current_store vendor/module/enabled 1
    public function testShouldRedirectToForm()


I debugged into my plugin and it looks like the method is never called, even a die('HERE') in the aroundExecute method does not work. I've tried all the usual stuff (clearing cache, sandbox, generated) already.

When I dump $this->getResponse() in the test, it has a status code of 200 but the response content itself is empty.

EDIT: I've tried moving the plugin configuration from etc/frontend/di.xml to etc/di.xml with no success.

  • Did you clear the test sandbox after enabling your module?

    @AsadUllah But preference is not a good practice to do.
