Provide components integration testing

[konstantina-gramatova]

Enabling fast release cycles, better code quality and components integrity throughout the full development and deployment lifecycle is essential to ensure a stable and production-ready solution.

The following considerations are applicable for all integration tests to be provided:

• The tests have to be provided per component, i.e.
  • in the component's dedicated repository (e.g. integration directory in the root of the repository)
  • cover the functionalities provided by the component only
• The use cases must be tested E2E (where applicable)
  • the tests have to validate against an actual backend - an instance of the Eclipse Cloud2Edge package can be used
• The tests have to be easily executable
  • must be configurable enough to work both locally and in an automated environment
  • must be pluggable enough to work both against a real backend and a mocked one for offline/local development testing
• The tests have to be easily portable to enable quick automated environments integration for automated execution
  • use Go as an implementation language as it enables cross-compiling the TCs in statically linked executable binaries
  • Go is already the widely-adopted project's language which will enable harvesting code coverage from the TCs execution per component
