Hi, i woud like to do some automated backend tests in nestJS. is there an easy way get credentials, for some "dev users" in development stage?

the best way to do this is to run a self hosted core with in memory database and connect to that during testing

and then, the idea is to clear the db for each test?

You can do that by making a new app in the in memory db for each test and deleting that app.

Even though the link above says it’s a paid feature, for in memory db, it’s totally free

how do i launch the in memory version? dont tprovide a db?
