This is a project specific .autotest file that allows me to run the tests for the Community Engine plugin when I override classes in my main project. This way, I know anytime my social networking site breaks core CE functionality. The PLUGIN_TEST_TO_IGNORE array keeps track of CE features whose tests will break because I've cut off routes to them or disabled them in some way. The goal is to keep CE pristine in the vendor directory, make all changes to the parent app, and use autotest to catch any errors I introduce.

Let .autotest run your plugin tests

PLUGIN_PATH = "vendor/plugins/community_engine/"
PLUGIN_TESTS_TO_IGNORE = ["functional/skills_controller_test.rb",
                          "functional/posts_controller_test.rb"].collect { |t| "#{PLUGIN_PATH}test/#{t}"}
