Question # 8

In a code review of a merchantâ€™s site you have discovered that there are multiple observers for the checkout_submit_all_after event. After closer inspection, you notice one of these observers is relying on the others being executed before it is called.

What risk does this pose, and how can it be mitigated?

There is no risk posed as long as each event observer specifies a correct sortOrder. Nothing needs to be changed.

Event observers are fired in alphabetical order of the observer name. There is no risk here.

Magento only supports one observer per event. These observers will need to be combined into a single point of customization.

Order of listener execution cannot be guaranteed, resulting in a fragile implementation. This code should be re-worked using plugins

Question # 12

The constructor function for \Magento\Catalog\Model\Category contains this excerpt:

With the automatic dependency injection that Magento provides, how is the StoreManagerInterface resolved?

If no $storeManager is provided, Magentoâ€™s code generator creates a shell concrete class based on \Magento\Store\Model\StoreManagerInterface

Magento finds all classes that implement \Magento\Store\Model\StoreManagerInterface (ordered alphabetically) and injects the first class.

Magento looks to the di.xml files in the entire system for a preference node for \Magento\Store\Model\StoreManagerInterface. This class is constructed and injected

Magento throws an exception because you cannot instantiate an interface
