Trouble testing plugin with object manager

Question

Issue: When attempting to test a plugin "after" method with $objectManager->create('Shopgate\Base\Model\Config')->startup(), the original startup() method is called but not my plugins afterStartup()

Steps Taken:

• [✔] Confirm module enabled & loaded
• [✔] Clear cache with magento cache:clean config
• [✔] Empty generated code with rm -r generated/*
• [✔] Register plugin as shown below:

In my etc/di.xml, I have the following:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Shopgate\Base\Model\Config">
        <plugin name="bugFixEnableGetSettings" type="MoninGlobal\ShopgateBugfix\Plugin\ShopgateConfig" sortOrder="9999" />
    </type>
</config>

In MoninGlobal\ShopgateBugfix\Plugin\ShopgateConfig I have:

    public function afterStartup($subject, $result){
        var_dump(get_class($subject));
        var_dump($result);

        return $result;
    }

The same occurs when using get() instead of create() on the object manager.

Any insight into what I am missing here would be greatly appreciated.

Despite Magento showing that the module had been loaded and enabled, my registration.php was incorrect:

Bad

use \Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(
    ComponentRegistrar::MODULE,
    'MoninGlobal_Template', # <--- BAD REFERENCE
    __DIR__
);

Good

use \Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(
    ComponentRegistrar::MODULE,
    'MoninGlobal_ShopgateBugfix',
    __DIR__
);
