junit - Apache Camel Beans Unit Testing -

i using apache camel spring boot in application. working on unit test.

java code

• dataroute class

  from("direct:getdata") .routeid("getdata") .bean(dataservice.class, "processdata") .marshal().json(jsonlibrary.jackson) .end(); 

• dataservice class

  public data processdata() {     return new data("hello world"); } 

• data class getters, setters , jackson tostring method

  private string value; 

unit test

• basecamelcontextunittext

  public abstract class basecamelcontextunittest extends cameltestsupport {      @autowired      private dataservice dataservice;       @produce      private producertemplate producertemplate;       public camelcontext getcamelcontext() {          return camelcontext;      }        @override      protected context createjndicontext() throws exception {          jndicontext context = new jndicontext();          context.bind("dataservice", dataservice);          return context;      }       @test      public void shouldprocessdata() throws exception {           routedefinition routedef = getcamelcontext().getroutedefinition("getdata");           routedef.advicewith((modelcamelcontext) getcamelcontext(), new routebuilder() {               @override              public void configure() throws exception {                   from("direct:getdata")                     .pipeline("bean:dataservice?method=processdata");              }      });       getcamelcontext().start();       string responsedata = "{"         + "\"value\":\"unit test success\""         + "}";       object response = producertemplate.sendbody("direct:getdata",   exchangepattern.inout, null);       bytearrayoutputstream bytearrayoutputstream = new bytearrayoutputstream(); ((inputstreamcache) response).writeto(bytearrayoutputstream);       assertthat(new string(bytearrayoutputstream.tobytearray()), is(responsedata));      }   } 

how mock

   .bean(dataservice.class, "processdata") 

in unit test return mock data object default string variable "unit test success" , test see if route give mocked object instead of object "hello world" string variable?

you can autowired dataservice in dataroute like

@component public class dataroute extends routebuilder {      @autowired     private dataservice dataservice;      @override     public void configure() throws exception {         from("direct:getdata")         .routeid("getdata")         .bean(dataservice, "processdata")         .marshal().json(jsonlibrary.jackson)         .end();     }  } 

so can mock dataservice usual.

an alternative using beanref("beanname", "methodname") in route.
