Test fixture persistence with NoSQL DBs in Phoenix and Ecto? (Unique constraint violations)

I’m using ArangoDB through the arangox_ecto package. I had to remove the ecto_sql package to get things to work properly. I’m still having trouble with the persistence of test fixtures, as they are not removed from the database between tests. This means that when another test tries to create the same test fixture, I get a unique constraint violation.

How can I fix this so that the fixtures are cleaned up properly, as happens with the SQL Sandbox adapter.

@TomGrozev if you see this I’d love your input.
