In Ruby on Rails + RSpec, I operate by injecting initial data with SeedFu.seed before running tests.

When you want to change the seed file loading path, you can pass the path as an array to SeedFu.fixture_paths.

# spec/spec_helper.rb

RSpec.configure do |config|
  # Seed_fu
  config.before(:suite) do
    SeedFu.fixture_paths = [
      "#{Rails.root}/db/fixtures",
      "#{Rails.root}/db/fixtures_initialization"
    ]
    SeedFu.seed
  end
end

That’s all from the Gemba.
