java - How to properly test a Spring Boot using Mockito -


i never did test , decided first. using spring boot , default layout follows: https://zapodaj.net/c8b65f1644e95.png.html file created on startup looks this

@runwith(springrunner.class) @springboottest public class restwebservicesapplicationtests {      @test     public void contextloads() {     }  }

i not change here, because not need it. contrast, created new class

public class checkuserdatarestcontrollertest {      @mock     private userservice userservice;      @injectmocks     private checkuserdatarestcontroller checkuserdatarestcontroller;      private mockmvc mockmvc;      @before     public void setup() {         mockitoannotations.initmocks(this);          mockmvc = mockmvcbuilders.standalonesetup(checkuserdatarestcontroller).build();     }      @test     public void textexistsusername() throws exception {         mockmvc                 .perform(get("/checkusernameatregistering")                 .param("username", "jonki97"))                 .andexpect(status().isok());     } }

to test controller method, should return status ok.

@getmapping("/checkusernameatregistering") public httpentity<boolean> checkusernameatregistering(@requestparam string username) {             return responseentity.ok().body(!userservice.existsbyusername(username)); }

however, during test, throws me out

java.lang.assertionerror: status  expected :200 actual   :404  <click see difference>      @ org.springframework.test.util.assertionerrors.fail(assertionerrors.java:54)         ...

this tested controller: https://pastebin.com/mww9ywih

i did not make special configurations because did not find out needed something.

the error 404 means mock not recognize endpoint test. end point should be:

 @test     public void textexistsusername() throws exception {         mockmvc                 .perform(get("/checkuserdata/checkusernameatregistering")                 .param("username", "jonki97"))                 .andexpect(status().isok());     }

hope help.

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
