MockMVC tests how can I verify the answer

Question

I have a following test method in mockMVC

I need to improve the tests to make sense. at the moment tests are not testing, how to improve to test? just add verification of data compliance? how to add it? What could be the example of data validation verification? how to test if UUID agrees?

how to improve these tests?

Answer 1

You could do something like this:

@Test
public void createUser() throws Exception {
    User user = userRepository.save(new User("testname", "testemail", 10));
    String userJson = toJson(user);

    this.mockMvc.perform(post("/user/add/")
            .contentType(contentType)
            .content(userJson))
            .andExpect(status().isCreated());
}

or

@Test
public void getUserById() throws Exception {
    User user = userRepository.save(new User("testname", "testemail", 10));   
    mockMvc.perform(get("/user/" + user.getId()))
            .andExpect(status().isOk())
            .andExpect(content().contentType(contentType))
            .andExpect(jsonPath("$.id", is(user.getId())))
            .andExpect(jsonPath("$.username", is(user.getUsername())))
            .andExpect(jsonPath("$.age", is(user.getAge())))
            .andExpect(jsonPath("$.emailAddress", is(user.getEmailAddress())));
}
