I have a method which returns void . However when I run the test I get error stating

java.lang.AssertionError: unexpected invocation: brmUserBo.saveUser(<com.arisglobal.agBRM.user.entity.BrmUser@16672d6>)

expectations:

  allowed, never invoked: brmUserBo.saveUser(<com.arisglobal.agBRM.user.entity.BrmUser@16672d6>); returns a default value

Here is my test :

public void testsaveUsers() {

            try {

                  final  Mockery context = new  JUnit4Mockery()  {{

                    setImposteriser(ClassImposteriser.INSTANCE);

                }};

                  final BrmUserBoImpl userBo = context.mock(BrmUserBoImpl.class);

                  final BrmUser user = new BrmUser();

                  BrmUserServiceImpl userService = new BrmUserServiceImpl();

                  userService.setBrmUserBo(userBo);

                  context.checking(new Expectations() {

                        {

                              allowing(userBo).saveUser(user);

                        }

                  });

                  userService.saveUser(user);

            } catch (Exception e) {

                  fail();

            }

      }
