How to Stub ActionController#render for Testing

Sometimes you just want to ensure that render will get called with the correct parameters in a test. Say, for instance, if you have your own special site_render method that examines subdomains or other info about the current request, and then does the real render based on that. This little test helper [...]

Continous Builder gets some Campfire love

I noticed a recent check in on the Rails timeline to the Continuous Builder plugin. DHH has added Campfire integration - so now you can get notified in real time chat about the chump who broke the build, and then proceed to mock them.
Peer pressure can be a powerful thing, so grab [...]

Five Ruby Blogs to Feed Your Head (and Soul)

I subscribe to far too many feeds. I never catch up, and recently somehow blew away my entire "non-ruby programming blogs" folder in NetNewsWire, and didn't really notice (or care).
That said, I think its important to keep up with the Ruby "blogs", as kids call them these days, if only because things [...]

Adding your Lib Tests and Plugin Tests to Autotest

My work lately has involved managing a lot of common code across three different Rails projects, some of it managed by svn:externals in /lib and some in plugins. So since I've been using ZenTest's autotest (which is very nice with the growl and redgreen plugins in 3.4), naturally I want the lib and vendor/plugin [...]

Accessing Rails Configuration and database.yml Programatically

I changed our database.yml to use merge keys, but we have a case where the host is different for production from all the other environments. I wanted to test and ensure the prod db host remained correct with the yaml merge - the docs say it works like hash#merge, but you don't wanna mess [...]

Using Autotest with Integration Tests

Autotest by default doesn't try to do anything with integration tests...since they can test so many files, its impossible to map x controller and z model to a integration test. However, that shouldn't prevent it from at least rerunning an integration test when there are changes to the integration test itself, and also running [...]

Hacking green bar color output into Autotest

update: You don't need to do this hack anymore - the RedGreen plugin is builtin into autotest with the latest versions.
A much welcome upgrade of the indispensable autotest recently came out which speeds things up greatly, but the output was still plain test_unit output. There are now hooks to add plugins to add widgets [...]

Testing named routes or url_for in functional test

If you've ever tried using named routes or url_for in functional tests, you might have seen an error like this:
1) Error:
test_article_override_to_meta(ArticleControllerTest):

The error occured while evaluating nil.rewrite

Testing the ApplicationController in Rails

Not sure why this test case isn't generated right away, but here it is:

require File.dirname(__FILE__) + '/../test_helper'
require 'application'
# Re-raise errors caught by the controller.
class ApplicationController; def rescue_action(e) raise e end; end
class ApplicationControllerTest <Test::Unit::TestCase
 
  def setup
    @controller = ApplicationController.new
  end
 
# your test here
  def test_truth
    assert true
  end
end
