Unit testing

@Test
void deleteTask() {
    Task testTask = new Task("Test 1", "some test description 1", false);
    taskRepository.save(testTask);
    taskRepository.deleteById(testTask.getId());
    //Search the Task Validating if yet exist
        Optional<Task> taskFound = taskRepository.findById(testTask.getId());
        assertEquals(Optional.empty(),taskFound);
    }

Other test

    boolean changeDoneTask (Long id){
        Task task = taskRepository.findById(id)
                .orElseThrow(() -> new ResourceNotFoundException("The task not exists in the id " + id));
        boolean stateStarted = task.isDone();
        task.setDone(!task.isDone());
        Task updatedTask = taskRepository.save(task);

        if(stateStarted != updatedTask.isDone()){
            return true;
        }else{
            return false;
        }
    }

    @Test
    void updateTaskDone() {
        Task testTask = new Task("Test 1", "some test description 1", false);
        taskRepository.save(testTask);
        assertTrue(changeDoneTask(testTask.getId()));
