Integration testing ReactiveMongo

During the development of Moresby Stroll I had to solve the testing of our data access layer. Moresby Stroll Server uses Akka Actors as a base of its architecture, therefore the data access layer is implemented by an Actor, the DataAccessActor.

DataAccessActor is responsible to provide all the persistence functionality what the business logic and higher layers require. Let's take a look at the DataAccessActor.

Scala persistence

I have been examining the persistence solutions in Scala to use one of them in our project

I found there are 4 ways:

• SQL
• Hibernate/JPA
• Type-safe SQL
• Scala syntax db access

The post about the Scala persistence is coming so please be patient.
