Rails - Nov 2005 - [OT - slightly] How to run plugin tests ?

Hi !

I'm building a plugin, and I'd like to add tests, following Jamis
Buck's suggestion.

This is my whole Rakefile:
require 'rake'
require 'rake/testtask'
require 'rake/rdoctask'

task :default => :test_units

desc "Run the unit tests in test/unit"
Rake::TestTask.new("test_units") do |t|
  t.pattern = 'test/unit/**/*_test.rb'
  t.verbose = true
end

I copied bits and pieces from the Rails 0.14.2 and Rails 0.13.1
Rakefiles, but when I run the test_units task, my tests don't run. 
For example, this is one of my tests:
require 'test/unit/testcase'
require 'francois_beausoleil/flash_plugin_helper/application'

class ApplicationTest < Test::Unit::TestCase
  def test_nothing
    flunk
  end
end

puts "ApplicationTest finishing..."

Even though I flunk the test, nothing happens.  The rake test_units
task finishes happily.

So, what am I missing ?  I know this is not Rails specific, but since
this is for a plugin...

Thanks !

I''d like to read more information about this same topic. Hopefully some
more
plugin development documentation will appear soon.

Right now I''m testing my plugin using the main unit tests for my Rails
application because it is so convienent. However the results of

rails script/generate plugin acts_as_fox

hints that testing the plugin directly is the right way to go. Still seems
like a struggle for me.

Maybe it could be possible to allow plugin tests to be run in the  
same context where Rails'' tests run? So that the plugin would get  
access to the sample data (with customers etc.) as well as controllers.

There is a task in 0.14.3 which does this, sort of:

rake test_plugins

Your plugin should have a test/ directory as normal, and it might be a
good idea to set up a test_helper in there to point to the right
fixtures, etc. For the LoginEngine (which is still a plugin, mind),
I''ve got the following:

  require File.dirname(__FILE__) +
''/../../../../test/test_helper'' #
the default rails helper

  # TODO: Add check for database-specific sql files instead
  load(File.dirname(__FILE__) + "/../db/schema.rb")

  Test::Unit::TestCase.fixture_path = File.dirname(__FILE__)  +
"/fixtures/"
  $LOAD_PATH.unshift(Test::Unit::TestCase.fixture_path)

  require File.dirname(__FILE__) + ''/mocks/time''
  require File.dirname(__FILE__) + ''/mocks/mail''

... and each test_ file having:

  require File.dirname(__FILE__) + ''/../test_helper''   # the
plugin''s
own test_helper


That might be a reasonable starting point....

Yes, but what about plugins that don't have models, yada ?  Such as
the FlashHelperPlugin ?  I don't need a full Rails environment to test
the plugin.  That's overkill.  Mind you, if that's the only way I'll
be able to test, I'll do it that way.

Anyway, thanks for the input !

If you don''t need models, chances are you don''t need to load
the Rails
environment. Have a look at the tests in the Engines plugin for an
example....

What about plugins that interact with things in the Controller like the
Flash hash (I''m trying to write an extension to the FlashHelper plugin
and
I''m having no luck running the tests at all!).
