groovy - spock possible bug? -

here're of base interfaces:

public interface parsingservice {    boolean isqualifiednode(resource resource) }  interface indexbuilder {     boolean buildsingleresource(resource resource) }   // osgi component. implementation indexbuilder @component(     immediate = true ) @service class solrindexbuilder implements indexbuilder {   list<parsingservice> parsers       @override     public boolean buildsingleresource(resource subject) {         boolean success = true         solrclient client = serverconfiguration.getsolrclient()          (parsingservice parser : parsers) {             try{                 if(parser.isqualifiednode(subject)) {                     client.commit()                 }                 else {                     log.debug(" ${subject.path} not qualified parsing parser: ${parser.servicesummary}")                     continue //continue trying next parser                 }             } catch (exception e) {                 success = false                 log.error("error while parsing resource: ${subject} parser: ${parser.servicesummary}")                 continue //continue trying next parser             }         }         return success     } } 

and here's corresponding spock unit-test

class solrindexbuilderspecification extends specification {     solrindexbuilder indexbuilder     solrclient mockclient = mock()     solrserverconfiguration mockserverconfiguration = mock()     parsingservice parser = mock()     parsingservice parser_page = mock()     parsingservice parser_asset = mock()      def setup(){         indexbuilder = new solrindexbuilder()         mockserverconfiguration.getsolrclient() >> mockclient     }      def "testing buildsingleresource: parsers qualify node, process node under scrutiny"() {         setup:         resource pageresource = mock()         parser.isqualifiednode(_) >> false         parser_page.isqualifiednode(_) >> true  // why not return true in method under test?          indexbuilder.parsers = arrays.aslist(parser,parser_page)          when:         indexbuilder.buildsingleresource(pageresource)          then:         1 * parser.isqualifiednode(pageresource)         1 * parser_page.isqualifiednode(pageresource)         /*          * todo: troubleshoot below when have time.          * parser supposed invoke mockclient.commit() call once. invocation clause:          *   1 * mockclienct.commit()          *          * should yield true.  however, doesn't hold. instead invocation clause:          *   0 * mockclient.commit()          *          * holds true.           */         0 * mockclient.commit()  // shouldn"t !! 1 of parsers should return true 'isqualifiednode(..)'     } } 

as can see in test under investigation: have 2 mocks 'parsingservice' interface defined. 'parser' , 'parser_page'. also, 1 of them designed return true when .isqualifiednode(..) method called. however, both of them, false returned. why ? can try recreate this. more look, more i'm convinced bug, unless don't understand fundamental spock!

get rid of

    parser.isqualifiednode(_) >> false     parser_page.isqualifiednode(_) >> true 

and change

    1 * parser.isqualifiednode(pageresource)     1 * parser_page.isqualifiednode(pageresource) 

to

    1 * parser.isqualifiednode(pageresource) >> false     1 * parser_page.isqualifiednode(pageresource) >> true
