### Question:
SolverHandler { protected boolean hasImproveSolutionOnBackgroundDuration() { return config.getImproveSolutionOnBackgroundDuration().toMillis() > 0; } SolverHandler(final SolverDef solverDef,
                         final KieServerRegistry registry,
                         final TaskAssigningRuntimeDelegate delegate,
                         final UserSystemService userSystemService,
                         final ScheduledExecutorService executorService,
                         final SolverHandlerConfig config); void start(); void destroy();  }### Answer:
@Test public void hasImproveSolutionOnBackgroundDuration() { assertThat(handler.hasImproveSolutionOnBackgroundDuration()).isTrue(); }
