Scenarios is a little RubyGem for organizing arbitrary snippets of Ruby code.

We specifically use it to load up the development database with data. It’s especially powerful in combination with a nice factory gem like Factory Girl / Object Daddy or, for loading up the database with lots of data, a data generation gem like Faker

To load up the development data with scenario(s) …

1 $ rake scenarios:load NAME=dependencies,create_lots_of_data

It can also be useful to use scenarios from tests/specs

1 describe 'Home Page' do
2 
3   scenarios :dependencies, :website_pages
4 
5   it 'should actually show something on the home page'
6 
7 end
