I got some test setup with sandbox db connection in my testcases. I configured text.exs to use a different db for the testcases and everything works as intended. The only thing which does not work properly is dropping the db before creating, migrating and seeding. The occurred error specifies that there is already an open connection to the db:
$ mix test
** (Mix) The database for MyApp.Repo couldn't be dropped: ERROR 55006 (object_in_use) database "test" is being accessed by other users
There is 1 other session using the database.

config :my_app, MyApp.Repo,
adapter: Ecto.Adapters.Postgres,

[
#when calling "mix test" elixir sets the ENV to :test automatically, if you call a different task you need the code below

]
end
In test_helper.exs i just do the recommended ExUnit.start() and Ecto.Adapters.SQL.Sandbox.mode(MyApp.Repo, :manual).
I don’t get where the connection is being accessed before and how can i fix that, so i can drop the db.
