MultipartFile-Upload-Test im Spring Boot fehlgeschlagen - nicht sicher warum

Question

Ich teste eine POST-Methode in einem Controller, der das Hochladen eines Bildes über eine MultipartFile behandelt. Es darf leer sein, aber wenn eine Datei vorhanden ist, sollte sie hochgeladen werden. Ich schrieb einen Komponententest, um sicherzustellen, dass es funktioniert, aber der Test schlägt fehl und gibt einen 404 zurück, und ich bin mir nicht sicher warum - wahrscheinlich, weil ich nicht geschickt darin bin zu lesen, was passiert. Hier ist der Test:

@Test 
    public void saveAnEntryWhenPOSTNewUserWithAPicture() throws Exception { 
    MockMultipartFile multiPFImage = new MockMultipartFile("ABCPicture", "abcpic.png", 
      "img/png", "Generate bytes to simulate a picture".getBytes()); 
    mockMvc.perform(MockMvcRequestBuilders.fileUpload("/newcontact") 
      .file(multiPFImage) 
      .param("userId", "12345") 
      .param("name", "Picture Uploader User")) 
      .andExpect(status().isOk()) 
      .andExpect(content().string(containsString("savedContact"))); 
    } 

Und hier ist der Stack-Trace, der vom Laufen, dass Testergebnisse:

Edit:

Hier ist die Controller-Methode, die getestet wird:

@PostMapping(path = "/newContact") 
    public String createNewContact(@ModelAttribute ContactDTO newContact) { 
    Contact contact = new Contact(newContact.getUserId(), newContact.getName()); 
    setOptionalContactFields(contact, newContact); 
    contactDAO.save(contact); // contactId automatically generated here (via SQL autoIncrement) 
    newContact.setContactId(contact.getContactId()); // update the newContact to include the contactId 
    if (newContact.getContactImg() !=null) { 
     uploadContactProfileImg(newContact); // handles actual saving of image to persistence layer 
    } 

    return "savedContact"; // assumes template that can display all fields of a Contact will be returned 
    } 

Jede Einsicht würde sehr geschätzt werden.

Answer 1

fand ich heraus, dass man vertippt haben MockMvcRequestBuilders.fileUpload("/newcontact")

MockMvcRequestBuilders.fileUpload("/newContact")

Zusätzliche sein sollte: Es ist ein Tippfehler in Ihrem DTO

public class ContactDTO { 
    private MultipartFile conactImg; 
} 

Anfrage mehrteiliger Name gleich mit DTO sein sollte, ABCPicture sollte conactImg

sein
