junit - Spring Boot unit testing a Service, manual tests pass but mocked service fails -

in order test service logic have set initial test data in 3 repositories. bit of test working, updates service supposed make never happen in repositories , test fails. if show test followed service logic more clear i'm trying do.

i think i'm missing annotations mocking service properly. think mocked service not connected mocked repository. don't know specific configurations add.

here code:

test:

package portal.services;  import static org.junit.assert.assertequals;  @runwith(springjunit4classrunner.class) @datajpatest public class testrunservicetest {     @mockbean     private testrunservice testrunservice;     @autowired     private testrunrepository testrunrepository;     @autowired     private testcaserepository testcaserepository;     @autowired     private testtoolrepository testtoolrepository;     @autowired     private testsuiterepository testsuiterepository;      testcase testcase = new testcase();     testtool testtool = new testtool();     testsuite testsuite = new testsuite();     testrun testrun = new testrun();      @before      public void createtestdata(){         // create test case         testcase.setid(1);         testcase.setname("agent charities");         testcaserepository.save(testcase);          // create test tool         testtool.setid(1);         testtoolrepository.save(testtool);          //create test suite         testsuite.setid(1);         testsuite.settestcase(testcase);         testsuite.settesttool(testtool);         testsuiterepository.save(testsuite);          // create test run         testrun.settestsuite(testsuite);         testrun.setstartdatetime(new date());         testrun.setenddatetime(new date());     }      @test     public void aggregatedatacountwhenresultispass(){          // test run result true 5 data items         testrun.setresult(true);         testrun.setgenerateddatacount((long)5);         testrunservice.add(testrun);          // test run result false 3 data items         testrun.setresult(false);         testrun.setgenerateddatacount((long)3);         testrunservice.add(testrun);          // test fails because testrunservice did not persist data         system.out.println(testrunrepository.count()); //output = 0          // test tool , test case repositories should show count of 5         assertequals((long)5, testcaserepository.findbyid((long)1).getgenerateddatacount().longvalue());         assertequals((long)5, testtoolrepository.findbyid((long)1).getgenerateddatacount().longvalue());         // test failed nullpointerexception, generateddatacount not updated testrunservice     }  } 

service:

public interface testrunservice {     iterable<testrun> listalltestruns();     testrun gettestrunbyid(integer id);     responseentity<?> add(@requestbody testrun input); }   @service public class testrunserviceimpl implements testrunservice {      private testrunrepository testrunrepository;     private testsuiterepository testsuiterepository;     private testcaserepository testcaserepository;     private testtoolrepository testtoolrepository;      @autowired     public void settestrunrepository(testrunrepository testrunrepository) {         this.testrunrepository = testrunrepository;     }     @autowired     public void settestsuiterepository(testsuiterepository testsuiterepository) {         this.testsuiterepository = testsuiterepository;     }     @autowired     public void settestcaserepository(testcaserepository testcaserepository) {         this.testcaserepository = testcaserepository;     }     @autowired     public void settesttoolrepository(testtoolrepository testtoolrepository) {         this.testtoolrepository = testtoolrepository;     }      @override     public iterable<testrun> listalltestruns() {         return testrunrepository.findall();     }      @override     public testrun gettestrunbyid(integer id) {         return testrunrepository.findone((long)id);     }      @override     public responseentity<?> add(@requestbody testrun input) {          // save te test run         testrun result = testrunrepository.save(input);         uri location = servleturicomponentsbuilder                 .fromcurrentrequest().path("/{id}")                 .buildandexpand(result.getid()).touri();          // update runtime total test tool         testsuite suite = testsuiterepository.findbyid(result.gettestsuite().getid());         testtool tool = testtoolrepository.findbyid(suite.gettesttool().getid());         tool.settotalruntime(result.getruntimemilliseconds());          // if run pass, update generated data count         if (result.getresult() == true){             tool.setgenerateddatacount(result.getgenerateddatacount());         }         // save updated test tool information         testtoolrepository.save(tool);          // update runtime total test case         testcase testcase = testcaserepository.findbyid(suite.gettestcase().getid());         testcase.settotalruntime(result.getruntimemilliseconds());          // if run pass, update generated data count         if (result.getresult() == true){             testcase.setgenerateddatacount(result.getgenerateddatacount());         }         // save updated test case information         testcaserepository.save(testcase);          return responseentity.created(location).build();             } } 

the thing know service works through manual testing , inspecting database, it's frustrating me can't unit test pass.

i'm not sure why using @mockbean annotation service.

can try constructing proper testrunservice object in setup method , use that?

for example:

@before  public void createtestdata(){      //set service      testrunservice = new testrunserviceimpl();      //invoke repository setters on service object      //data creation      }
