Rails 5: Is there a way to run a single set of tests against the development database?

I would like to run a single set of tests against the development database. My seeds.rb file populates the databse from a CSV and I want to ensure that the data is stored in the database in the way I expect. I don't want to run all tests against the development database, just a particular set.

seeds.rb

I created an integration test. I thought I could switch environments in #setup but it looks like Rails.env = 'development' has no effect.

#setup

Rails.env = 'development'

require 'test_helper'

class DbTest < ActionDispatch::IntegrationTest
def setup
Rails.env = 'development'
end

def test_total_settlements
...


Is it possible to run tests in different environments? If so, how is this done?

I'd recommend to create a class to seed the information into a configurable database, and then run tests against that class. In that way, you don't need to run the tests to an operational database and run that tests the number of times you want, without having to manually modify your development database in case the seed failed (like removing leftover records).

Once you have that class, you could add a task to your Rakefile and use your class :)

In my opinion, the simplest solution would be to just seed your test database.
You can call Rails.application.load_seed before the tests you need seed data for.

Rails.application.load_seed
