grails - How can I unit test a controller using altered default date binding? -

how can simulate behavior of grails.databinding.dateformats in controller spock test?

in config.groovy, added these settings:

grails.databinding.dateformats = [     'yyyy-mm-dd\'t\'hh:mm:ss.sssx',     'yyyy-mm-dd\'t\'hh:mm:ssx', ] 

what have unit test framework bind date properties using 1 of specified formats?

my controller looks like:

class mycontroller {     static responseformats = ['json']      def get() {         mycommand command = binddata(new mycommand(), params)          command.validate()         if (command.haserrors()) {             ...         }         else {             //...do stuff command object         }     }      @validateable     class mycommand {         long resourceid         date startdate         date enddate         static constraints = {             resourceid nullable: false             startdate nullable: false             enddate nullable: false         }     } } 

when run application, code works normally; however, when binddata() called in unit test, 'resourceid' property on command object populated, while date properties not.
