Configuration
Tamarama uses the dotenv gem for managing environment variables such as database connection strings.
For you, this boils down to providing .env.development and .env.test files in the project root. Check out example.env.test for an example of what such a config file might look like.
# .env.test
DATABASE_URL="postgres://user:password@localhost/myblog_test"
Migrations
RACK_ENV=test rake db:migrate
RACK_ENV=test rake db:migrate[0]
Testing Connection
RACK_ENV=test rake db:debug
