Testing plugins in Redmine 2.x

Added by Harry Garrood over 12 years ago

I am trying to write tests for my redmine 2.x plugin. I've read http://www.redmine.org/projects/redmine/wiki/Plugin_Tutorial#Testing-your-plugin, and have created the following files in test/:

test_helper.rb
fixtures/release_notes.yml
unit/release_note_test.rb

Then, in release_note_test.rb, i call:

fixtures 'release_notes'

Unfortunately, this results in:

Errno::ENOENT: No such file or directory - /home/harry/code/redmine/test/fixtures/release_notes.yml

It seems Redmine is looking in its own fixtures directory, and not my plugin's. Is there a good way of telling it to use the plugin's fixtures? I've considered adding code to copy fixtures to Redmine's own location in test_helper.rb but that feels very naughty...

I think I've fixed this, by using this in my test_helper.rb:

# Load the normal Rails helper
require File.expand_path(File.dirname(__FILE__) + '/../../../test/test_helper')

# Ensure that we are using the temporary fixture path
class ActiveSupport::TestCase
  self.fixture_path = File.dirname(__FILE__) + '/fixtures'
end

It seems this replace redmine fixtures and you will not be able to load redmine objects like issues for your tests. ActiveSupport::TestCase.fixture_path = File.dirname(FILE) + '/fixtures'

Yes, that's true. For the benefit of anyone else -- I've also copied issues.yml from redmine's fixtures directory into my plugin's fixtures directory to get around that.

For me it was solved by that code:

class ContactsControllerTest < ActionController::TestCase  
  fixtures :projects,
           :users,
           :roles,
           :members,
           :member_roles,
           :issues,
           :issue_statuses,
           :versions,
           :trackers,
           :projects_trackers

    ActiveRecord::Fixtures.create_fixtures(File.dirname(__FILE__) + '/../fixtures/', 
                            [:contacts,
                             :contacts_projects,
                             :contacts_issues,
                             :deals,
                             :notes,
                             :roles,
                             :enabled_modules,
                             :tags,
                             :taggings,
                             :contacts_queries])

Hello, Kirill.

Your code works fine for me, thank you so much!

Also I added this workaround in my plugin's test_helper.rb.

require File.expand_path(File.dirname(__FILE__) + '/../../../test/test_helper')
ActiveRecord::Fixtures.create_fixtures(File.dirname(__FILE__) + '/fixtures/',
                                       [:my_plugin_fixture_1, :my_plugin_fixture_2])

Hello,

I've packaged this feature in the plugin's test_helper.rb.

module Redmine
  module PluginFixturesLoader
    def self.included(base)
      base.class_eval do
        def self.plugin_fixtures(*symbols)
          ActiveRecord::Fixtures.create_fixtures(File.dirname(__FILE__) + '/fixtures/', symbols)
        end
      end
    end
  end
end

unless ActionController::TestCase.included_modules.include?(Redmine::PluginFixturesLoader)
  ActionController::TestCase.send :include, Redmine::PluginFixturesLoader
end

Then you can use the plugin_fixtures the same way you use fixtures.

I've tried these suggestions, but changing the value of fixture_path and using #create_fixtures has not allowed me to use methods like #my_models(:some_fixture), which is what I expect.

Is anyone using the techniques described above with the class accessor methods, or is everyone accessing the fixtures another way?

RE: Testing plugins in Redmine 2.x - Added by Harry Garrood almost 12 years ago

This doesn't really answer your question (I don't know the answer), but I gave up with fixtures and switched to factory_girl . I remember thinking it worked quite well for me. Definitely worth a try, at least.

Thanks Akiko Takano, that worked perfect. Justin, I thought it wasn't working either, but after you implement Akiko's solution, you must also include them in the fixtures declaration in your test class.

test_helper.rb

# Load the normal Rails helper
require File.expand_path(File.dirname(__FILE__) + '/../../../test/test_helper')
ActiveRecord::Fixtures.create_fixtures(File.dirname(__FILE__) + '/fixtures/', [:contracts, :user_contract_rates, :user_project_rates])

contracts_controller_test.rb

# include main and custom fixtures here
fixtures :issues, :projects, :users, :time_entries,
         :contracts, :user_contract_rates, :user_project_rates

def setup
    @contract = contracts(:contract_one)
    @project = projects(:projects_001)
    etc......
