Development Junit test notification

Question

I'm in the development phase of a Test class to test send notifications :

1- SMS (send SMS using phone number )

2- Email (send email )

3- WebSocket (send websocket )

This is the first time I have used Junit. It's working but I need a check of the quality of code. My project is a spring boot application rest API.

the below code test Class

@RunWith(SpringRunner.class)
@WebMvcTest(NotificationController.class)
@Import(TestConfigForMail.class)
@ActiveProfiles("local")
public class NotificationTest  {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private SpanAccessor tracer;


    /**
     * test send SMS notification 
     * @throws Exception
     */
    @Test
    public void testSMSNotification() throws Exception {
        Notifications notification=new Notifications();
        List<GeneralNotificationInfo> listNotifications=new ArrayList<GeneralNotificationInfo>();
        SMSNotification smsNotification=new SMSNotification();
        smsNotification.setTemplateId(1);
        smsNotification.setSmsTo(new String[] {"+10002222"});
        Message message=new Message();
        message.setTitle("HELLO FROM SMSNOTIFICATION TEST");
        message.setBody("HELLO FROM SMSNOTIFICATION TEST");
        smsNotification.setMessage(message);
        listNotifications.add(smsNotification);
        notification.setNotfication(listNotifications);
        ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
        this.mockMvc.perform(post(NotificationURI_Constants.SEND_NOTFICATION).contentType(
                MediaType.APPLICATION_JSON).content(ow.writeValueAsString(notification)))
        .andExpect(status().isOk())
        .andExpect(jsonPath("$.result.status.SMSNotification", is("TRUE")));

    }

    /**
     * test Email Notification
     * @throws Exception
     */
    @Test
    public void testEmailNotification() throws Exception {
        Notifications notification=new Notifications();
        List<GeneralNotificationInfo> listNotifications=new ArrayList<GeneralNotificationInfo>();

        EmailNotification emailNotification=new EmailNotification();
        emailNotification.setTemplateId(1);
        emailNotification.setEmail(new String[] {"[email protected]"});
        Message messageEmail=new Message();
        messageEmail.setTitle("HELLO EMAIL NOTIFICATION FROM TEST");
        messageEmail.setBody("HELLO EMAIL NOTIFICATION FROM TEST BODY");
        emailNotification.setMessage(messageEmail);
        listNotifications.add(emailNotification);

        notification.setNotfication(listNotifications);
        ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
        this.mockMvc.perform(post(NotificationURI_Constants.SEND_NOTFICATION).contentType(
                MediaType.APPLICATION_JSON).content(ow.writeValueAsString(notification)))
        .andExpect(status().isOk())
        .andExpect(jsonPath("$.result.status.EmailNotification", is("TRUE")));

    }


    /**
     * test Web Socket Notification 
     * @throws Exception
     */
    @Test
    public void testWebSocketNotification() throws Exception {
        Notifications notification=new Notifications();
        List<GeneralNotificationInfo> listNotifications=new ArrayList<GeneralNotificationInfo>();

        WebSocketNotification  webSocketNotification=new WebSocketNotification();
        webSocketNotification.setTemplateId(1);
        webSocketNotification.setUsersID(Arrays.asList(new String[] {"john"}));
        Message messageEmail=new Message();
        messageEmail.setTitle("HELLO WEBSOCKET NOTIFICATION FROM TEST");
        messageEmail.setBody("HELLO WEBSOCKET NOTIFICATION FROM TEST BODY");
        webSocketNotification.setMessage(messageEmail);
        listNotifications.add(webSocketNotification);

        notification.setNotfication(listNotifications);
        ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
        this.mockMvc.perform(post(NotificationURI_Constants.SEND_NOTFICATION).contentType(
                MediaType.APPLICATION_JSON).content(ow.writeValueAsString(notification)))
        .andExpect(status().isOk())
        .andExpect(jsonPath("$.result.status.WebSocketNotification", is("TRUE")));

    }
}

A few small tweaks that can improve the readability of your code:

Your code could really benefit from a few strategically placed white spaces.
Instead of instantiating objects at the start of a method and forgetting about them for 5+ lines, try creating your objects only when you must. Same idea applies when storing primitive types.
Be consistent with the spaces between your assignment operators.

Bringing the above ideas together might look something like this:

@Test
public void testSMSNotification() throws Exception {
    Message message = new Message();
    message.setTitle("HELLO FROM SMSNOTIFICATION TEST");
    message.setBody("HELLO FROM SMSNOTIFICATION TEST");

    SMSNotification smsNotification = new SMSNotification();
    smsNotification.setTemplateId(1);
    smsNotification.setSmsTo(new String[] {"+10002222"});
    smsNotification.setMessage(message);

    List<GeneralNotificationInfo> listNotifications = new ArrayList<GeneralNotificationInfo>();
    listNotifications.add(smsNotification);

    Notifications notification = new Notifications();
    notification.setNotfication(listNotifications);

    ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
    this.mockMvc.perform(post(NotificationURI_Constants.SEND_NOTFICATION).contentType(
            MediaType.APPLICATION_JSON).content(ow.writeValueAsString(notification)))
    .andExpect(status().isOk())
    .andExpect(jsonPath("$.result.status.SMSNotification", is("TRUE")));
}
