I’m a bit confused as to how Ecto works with seeded data when it is conducting its tests. What EXACTLY is the flow when you commence a test run (whether it be all of them via “mix test”, or only a specific file, or a specific test by specifying a line number)? Does the testing database get seeded in this process?
For example, I have some data (e.g. a list of countries) that should be the same in all environments. Do I need to explicitly seed that in the testing database? I have other data that I COULD seed ONLY in the test database just to help write thorough integration tests. How should that be best accomplished?
Thanks for any guidance!

mix testwon’t seed your database, because nothing will cleanup the data which was inserted outside of the sandbox transactions of single tests. Also having those countries seeded would mean they are the same to all tests, which imho can be as annoying as any other global state in your system. I’d rather opt for inserting those countries via a Factory on demand, so you can control on a per test basis which countries are in the database.Most Liked

Thank you, this is helpful – I need some time to digest it.
