+# VegetableGlue
+
+Easy way to start/stop/restart a dependent Rails API app in a consumer's acceptance tests.
+Uses `database_cleaner`'s `:truncation` mode to clean out your databases after each run.
+
+## Installation & Usage
+
+In both apps' Gemfiles:
+
+``` ruby
+gem 'vegetable_glue'
+```
+
+In the provider (API):
+
+* Create or use a Rails environment that has a database that you don't mind nuking (say `test`, `acceptance`, or `cucumber`)
+* Modify `config/routes.rb`:
+
+``` ruby
+require 'vegetable_glue/routes'
+
+MyApp::Application.routes.draw do
+  # ... your other routes ...
+
+  acceptance_helper_routes #=> for the :acceptance env, or
+  acceptance_helper_routes_for :cucumber #=> for the :cucumber env
+end
+
+The two additional routes are only added in that environment.
+
+In the consumer (Frontend):
+
+* For Cucumber, add the following to `features/support/env.rb`:
+
+``` ruby
+require 'vegetable_glue/cucumber'
+
+VegetableGlue.url = 'http://localhost:6161/' #=> include the port in here, too, that's where the app will run
+VegetableGlue.path = '../path/to/the/app'
+```
+
+The app will clean its database on each scenario. To restart the app, pass in the environment variable `GLUE_RESTART`:
+
+    GLUE_RESTART=true bundle exec cucumber
+
+If you're using ActiveResource, a good source of the URL is `ActiveResource::Base.site`.
+
+## Contributing

+1. Fork it
+2. Create your feature branch (`git checkout -b my-new-feature`)
+3. Commit your changes (`git commit -am 'Added some feature'`)
+4. Push to the branch (`git push origin my-new-feature`)
+5. Create new Pull Request
