[Lassal]

List all intermediate components that need to fully covered by Unit Tests.

Use Mockito to create the mocks.

Components to be covered:

• DBModelSerializer and all its children
• ParallelSerializer
• DBVersionCommand
• ParallelDBVersionCommand
• JacksonYamlSerializer : ? test all model serialization ?

[Lassal]

Create unit tests for each object serializer: TableSerializer, ViewSerializer, IndexSerializer, TriggerSerizalizer, and RoutineSerializer.

Mock all dependencies for database using Mockito.

We have covered the main component tests in the referenced tasks, the YAML serialization and deserialization were covered in the serializer tests and in the DBModelFS integration tests.
