The test endpoints used to create an order, add a product, confirm the
order and ship it are not embracing the asynchronous approach of the
CommandGateway. Make sure that all commands are composed with one
another and return the completable future for Spring to resolve
#BAEL-4767
Change PlaceOrderCommand/OrderPlacedEvent to
CreateOrderCommand/OrderCreatedEvent. Placed suggests it is already
placed, meaning products cannot be changed. However with the new
OrderLine member and its operations it's no longer correct to state the
order placed upon creation. Furthermore, the OrderedProduct is no longer
a single product, but contains several. Renaming this to Order is more
in line with what this query model resembles
#BAEL-4767
Add test cases to reach a 100% coverage of all message handling
functions of the OrderAggregate and OrderLine member. Added, upgrade to
JUnit 5
#BAEL-4767
Adjust the OrderAggregate to contain an OrderLine aggregate member. The
OrderLine is added as soon as a Product is added through the
AddProductCommand. The OrderLine member is capable of handling the
increment and decrement product count commands, to increase/decrease the
number of instances for that OrderLine. Decreasing the count below 1
will publish the ProductRemovedEvent from within the OrderLine.
Additional business validation is added to unsure a given Product isn't
added twice (adding a second should go through increment) and that the
products aren't adjusted as soon as the product is confirmed.
#BAEL-4767
- Introduce a DuplicateOrderLineException to signal whenever somebody
wants to add the same product twice instead of using the increment
command.
- Introduce OrderAlreadyConfirmedException to signal whenever the order
is confirmed, so that adding products and incrementing/decrementing
their count is not possible once the order has been confirmed
#BAEL-4767
- Adjust OrderPlacedEvent to only construct the order
- Introduce ProductAddedEvent to be able to add several products
to a order
- Introduce ProductCountIncrementedEvent to increase the number of
product instances for a given Order
- Introduce ProductCountDecrementedEvent to increase the number of
product instances for a given Order
- Introduce ProductRemovedEvent to signal whenever all the product count
drops below 1
#BAEL-4767
- Adjust PlaceOrderCommand to only construct the order
- Introduce AddProductCommand to be able to add several products to an
order
- Introduce IncrementProductCountCommand to increase the number of
product instances for a given Order
- Introduce DecrementProductCountCommand to increase the number of
product instances for a given Order
