I don't know the test harness but what is the issue with having testcontainers and docker? What would be the benefit using the harness (except it might be faster)?

[kevintanhongann]

It is faster to get things up and running to prototype quickly without spinning a docker instance (though it's not that urgent to include). Correct me if I'm wrong.
On the other hand, I really enjoyed what jhipster can do with neo4j since the AI hype has been picking up nowadays with graph databases.

I don't think we have any other database that could be used like this.
Actually it should be possible to use Neo4j https://neo4j.com/docs/java-reference/current/java-embedded.
Depending on the complexity we may accept PRs, but I think it should be closed since we prefer testcontainers for simplicity.

Embedded DB is more complex than testcontainers.
We should avoid more maintenance burden.
