seeds.rb isn't executed within database resets run by tests

I've attempted to use the seeds.rb to setup some low-level data in the database, which my code depends upon. In this specific case, I'm setting up a reference data table that backs a model, then I'm using this model and the assumed content to perform a join in a named_scope query of another model.

My tests are failing to run, as the seed data isn't available, so when the model is loaded and the named_scope is evaluated, the reference data isn't available to fulfill the setup of the query.
