Setup ArchUnit

[simonhir]

Is your feature request related to a problem? Please describe.

As a developer i want that the complete code complies with the ADRs. In specific i want that naming conventions, package structure is correctly used.

Describe the solution you'd like

• Setup ArchUnit tests
  • Need to be discussed where the tests should go
• Implement ADRs as ArchUnit tests (i.e. integrations hexagonal architecture and naming conventions)

Describe alternatives you've considered

• The code architecture is not checked and is not correctly implementing all ADRs

Acceptance Criteria

• [ ] It is defined where which ArchUnit tests should go
• [ ] ArchUnit verifies integration architecture, i.e.:
  • Package concerns
  • Naming conventions
