If I add code to my seed file to seed more tables, then re-run

prisma db seed --preview-feature

is that going to add duplicate seed data to previously seeded tables?

@Chris Tsongas 👋 Yes. You would need to add a check for the records if those are already added. Best to split those into separate functions and only call what’s needed for the latest migration.

@Ryan thanks. Seems like it would be ideal to also share those functions with integration tests that need seed data...know of any examples I could reference?

I would need to check if there are any examples, but you can always run

prisma db seed

before the test.

I just set up Apollo Server but have yet to start setting up tests. I remember reading about people generating random test database names so multiple tests can run in parallel, each against their own test database...would be amazing to see an example of that!

Ohh I do have an example for that here!
