java - Mockito when().thenReturn doesn't work -

-

i'm trying write tests spring controller , having problem. following code returns redirect:/welcome though have when(result.haserrors()).thenreturn(true); should return add. may i'm doing wrong. me solve this, please.

controller

@controller public class springcontroller {  @autowired private userservice userservice;  @autowired private correctvalidator correctvalidator;  @autowired private existvalidator existvalidator;  @autowired private unwrapper unwrapper;      @requestmapping(value = "/create", method = requestmethod.post)     public string create (wrapper wrapper,                       bindingresult result)         throws parseexception {         correctvalidator.validate(wrapper, result);         existvalidator.validate(wrapper, result);         if (result.haserrors()) {             return "add";         }         userservice.create(unwrapper.unwrap(wrapper));         return "redirect:/welcome";     } }

test

@runwith(springjunit4classrunner.class) @webappconfiguration @contextconfiguration(locations={"file:src/main/webapp/web-inf/spring-servlet.xml"}) @testexecutionlisteners({ dependencyinjectiontestexecutionlistener.class}) public class controllertest {  @injectmocks private springcontroller controller;  @mock private wrapper wrapper;     @mock private bindingresult result;  @before public void setup() throws exception {     mockitoannotations.initmocks(this);     mockmvc = standalonesetup(controller)             .setsingleview(mockview)             .build(); }      @test     public void testcreatebad() throws exception {         when(result.haserrors()).thenreturn(true);          mockmvc.perform(post("/create", wrapper, result))                 .andexpect(status().isok())                 .andexpect(view().name("add"));     }  }

the problem not using post() method correctly. see javadoc here.

in arguments pass 

post("/create", wrapper, result)

wrapper , result used url variables, not method arguments create method. cannot mock bindingresult way. it's extremely hard imo mock , not worth in long run. if should test command objects or won't valid.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
