Rails core - Nov 2011 - How to stub "install_using_#{method}" in railties/lib/rails/commands/plugin.rb

Dear all,

I am trying to write tests that test installation of plugins using "rails
plugin install xxx". So far I have setup a basic PluginTest class taking
inspiration from RunnerTest:

railties/test/application/plugin_test.rb

require ''isolation/abstract_unit''

module ApplicationTests
  class PluginTest < Test::Unit::TestCase

    def setup
      build_app
    end

    def teardown
      teardown_app
    end

    def test_successful_installing_of_plugin
      assert Dir.chdir(app_path) { `bundle exec rails plugin install
http://example.com/my_svn_plugin` }
    end
  end
end

When above test is run, it will try to _actually_ install my_svn_plugin.
The methods that cause installation of plugins are defined in
railties/lib/rails/commands/plugin.rb. These are install_using_export,
install_using_checkout, install_using_externals, install_using_http and
install_using_git defined as instance methods on Plugin class.

How can I stub these methods so that test does not try to _actually_
install a plugin? If there is another way I can avoid actual installation
in tests, I am open to that also. Please point me to some example code that
I can refer to.

I am doing this to fix issue #208[1]

Thanks!
