Interview Questions

How do you set the shipping address to the order or shipping group?

• We use the ShippingGroup droplet to display all the available shipping addresses. The ShiipingGroupDroplet will get the available addresses from the Profiles shipingAddress and secondaryAddresses properties.
• Then the user will select the shippingAddress from the list. 
• Then the selected address will be set the current shipping group by calling the handleApplyShippingGroups method of ShippingGroupFormHandler.
• We can create a shipping group manually by using the ShippingGroupManager.createShippingGroup by passing the address. After that we call ShippingGroupManager.addShippingGroupToOrder method.
• The user will also select the shipping method and set to the shipping group such as NextDay , Two Day or Ground.We will use AvailableShippingMethods droplet which fetches all the shipping methos names from the Shipping calculators. Each Shipping Calculator has a property called shiipingMethod.
