android - How verify the order of mock methods in JUnit -


i have class these structure , need test behaviour of onrequestlistoflunchsfinished interface

@override public void getlistoflunchs(final onrequestlistoflunchsfinished callback) {      zip().onerrorresumenext(new function<throwable, observablesource<? extends lunchserviceresponse>>() {          @override         public observablesource<? extends lunchserviceresponse> apply(@nonnull throwable throwable) throws exception {             callback.onerror(new runtimeexception(throwable));             callback.onend();              return observable.empty();         }      }).subscribe(new consumer<lunchserviceresponse>() {          @override         public void accept(lunchserviceresponse response) throws exception {             list<lunch> result = new arraylist<>();              list<ingredientresponsevo> ingredients = response.getingredients();             map<integer, ingredient> hash = new hashmap<integer, ingredient>();              (ingredientresponsevo vo : ingredients)                 hash.put(vo.id, new ingredient(vo.id, vo.name, new bigdecimal(vo.price.tostring()), vo.image));              for(infolunchresponsevo vo: response.getlunch()){                 lunch lunch = new lunch();                 lunch.setid(vo.id);                 lunch.setimage(vo.image);                 lunch.setname(vo.name);                  for(integer id : vo.ingredients){                     ingredient ingredient = hash.get(id);                     lunch.addingredient(ingredient);                 }                  result.add(lunch);             }              callback.onsuccess(result);             callback.onend();         }      });      callback.onstart(); }  private observable<lunchserviceresponse> zip(){     return observable.zip(getrequestoflistoflunchs(), getrequestoflistofingredients(), new bifunction<list<infolunchresponsevo>, list<ingredientresponsevo>, lunchserviceresponse>() {          @override         public lunchserviceresponse apply(@nonnull list<infolunchresponsevo> infolunchresponsevos, @nonnull list<ingredientresponsevo> ingredientresponsevos) throws exception {             return new lunchserviceresponse(infolunchresponsevos, ingredientresponsevos);         }      }); }

i have test method

@test public void teste(){     list<ingredientresponsevo> ingredients = collections.emptylist();     list<infolunchresponsevo> lunchs = collections.emptylist();      when(mockapi.getlistofingredients()).thenreturn(observable.just(ingredients));     when(mockapi.getlunchs()).thenreturn(observable.just(lunchs));      mockimplementation.getlistoflunchs(callback);      inorder order = inorder(callback);      order.verify(callback).onstart();     order.verify(callback).onsuccess(anylist());     order.verify(callback).onend();      order.verifynomoreinteractions(); }

but receiving exception:

org.mockito.exceptions.verification.verificationinorderfailure:  verification in order failure wanted not invoked: callback.onsuccess(<any>);

if this:

callback.onstart(); callback.onsuccess(collections.<lunch>emptylist()); callback.onend();  inorder order = inorder(callback);  order.verify(callback).onstart(); order.verify(callback).onsuccess(anylist()); order.verify(callback).onend();  order.verifynomoreinteractions();

this works.

how verify calls of mock callback?

you must not use inorder object.

mockimplementation.getlistoflunchs(callback);  mockito.verify(callback).onstart(); mockito.verify(callback).onsuccess(anylist()); mockito.verify(callback).onend();  mockito.verifynomoreinteractions();

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
