Culerity normally assumes you have JRuby installed somewhere on your system and in your environment. This fork embeds JRuby 1.4.0 (in the form of the jruby complete jar) within Culerity itself. This way, JRuby does not need to be installed system-wide.
Culerity integrates Cucumber and Celerity in order to test your application's full stack.
Culerity lets you:
- run Celerity from within Cucumber which allows you to test the full stack of your Rails (or other web) application from Database to in browser JavaScript
- run your application in any Ruby (like MRI 1.8.6) while Celerity runs in JRuby so you can still use gems/plugins that would not work with JRuby
- reuse existing Webrat-Style step definitions
The following guide is written for a Rails application (tested with 2.3.5) but Culerity should work with any other Web Framework that is supported by Cucumber.
Install the Culerity gem:
gem install culerity --source http://gemcutter.org
Assuming you have a Rails application set up already you can run the RSpec, Cucumber and Culerity generators:
cd RAILS_ROOT
script/generate rspec
script/generate cucumber
script/generate culerity
This creates the features folder and a file culerity_steps.rb into your application. This file contains step definitions for basic interactions like clicking links or filling out forms. Now is a good time to get rid of any webrat specific files generated by cucumber (i.e. features/step_definitions/webrat_steps.rb).
After you have written a first feature you can run it just like you would run a standard cucumber feature. The only difference is that you have to start a web server (e.g. mongrel) with the test environment enabled beforehand.
rake culerity:rails:start
cucumber features/my_feature.feature
The Rails instance uses a special environment culerity.
When you have finished running culerity/cucumber you can turn off the Rails instance:
NOTE: The default port for this server is 3001. You can change this in features/step_definitions/common_celerity.rb
rake culerity:rails:stop
If you are using RVM there's an integration guide for culerity on their website.
While Celerity is based on Java and requires JRuby to run, with Culerity you can still run your tests in your own Ruby Environment. When you run your features a separate JRuby process for Celerity is spawned and all Celerity Commands are redirected to this other process.
I get Connection Refused errors
- make sure you have started a server in the test environment that runs on port 3001
My application can't find the data I create in my steps
- make sure you have disabled transactional fixtures in your env.rb
My database is not cleared automatically between scenarios
-
Rails can't clean the database because you had to disable transactional fixtures - which only work if your test process is the same as your web server process. Hence you have to clean your database manually. A quick way would be:
Before do [User, .... all your models].each do |model| model.delete_all end end
