Hi guys, its probably a miss understanding of the framework but I need your assistance.
Here is the problem of one of my teammates: I have a hard time writing rspecs for a class I developed. The class in question reads an xml document, instanciates the model classes found in the xml and saves the classes and their attributes in the database with the good foreign keys. The class is stored in a lib. The class : class XmlReader def self.import_xml(xml_doc) objects_xml = Array.new keys_obj = Array.new xml = REXML::Document.new(xml_doc) read_xml(xml, objects_xml, keys_obj) raise AnError.new("Can not save xml objects") if (objects_xml.empty?) objects_xml.each { |instance| save_class(instance, keys_obj[objects_xml.index(instance)]) } end … end The import_xml function acts as an entry point but there are two other functions involved in the process : - read_xml : reads the xml elements one by one and instanciates the classes that have to be with the attributes found in the xml document. It is called recursively. The two arrays, objects_xml and keys_obj, contain respectively all the instanciated objects found and all the foreign keys defined in the relations of the models. - save_class : saves the instanciated objects contained in the objets_xml array with the good foreign keys for the relations to be well done. Now, I am trying to test if the objects_xml array is empty. If so, the class should raise an error. The rspec : # mocks … @mock_element = mock(REXML::Element) mock_element.stub!(:text) @mock_element.stub!(:name) @mock_element.stub!(:elements) @xml_doc = mock(REXML::Document, :elements => { "e1" => @mock_element, "e2" => @mock_element }) @xml_doc.stub!(:new) @xml_doc.stub!(:has_elements?) xml_doc.stub!(:encoding) @objets_xml = mock(Array) @objets_xml.stub!(:[]=) @objets_xml.stub!(:[]) objets_xml.stub!(:empty?) @keys_obj = mock(Array) @keys_obj.stub!(:[]=) @keys_obj.stub!(:[]) Array.should_receive(:new).and_return(@objets_xml) Array.should_receive(:new).and_return(@keys_obj) REXML::Document.should_receive(:new).and_return(@xml_doc) XmlReader.should_receive(:read_xml).and_return(true) objets_xml.should_receive(:empty?).and_return(true) lambda { XmlReader.import_xml(xml_valid) }.should raise_error(AnError, "Can not save xml objects") The error : undefined method `new' for ActiveSupport::Callbacks::CallbackChain:Class This is where my problem is. This error occurs after the test is made and finished. In other words, the test passes but the framework fails after it on a callback made in rails for whatever reason.

Many thanks in advance.
