AssertionError：在JSON路径上没有值，但是在有效的JSON响应中存在值

Question

我试图尽可能地保持代码清晰，所以我决定创建许多测试类，包括测试项，例如：

@Getter
@Setter
public class SalesTaskTestItem {

    public static SalesTask buildTestItem(){

        List<ContactPerson> contactPersonTestItemList = new ArrayList<>();
        contactPersonTestItemList.add(ContactPersonTestItem.buildTestItem());

        List<SalesMan> supportingSalesTeamList = new ArrayList<>();

        List<Product> discussedProductsTestList = new ArrayList<>();
        discussedProductsTestList.add(ProductTestItem.buildTestItem());

        List<SalesTaskProgress> progressTestList = new ArrayList<>();
        progressTestList.add(SalesTaskProgressTestItem.buildTestItemNo1());
        progressTestList.add(SalesTaskProgressTestItem.buildTestItemNo2());
        progressTestList.add(SalesTaskProgressTestItem.buildTestItemNo3());

        List<Offer> alreadySentOffersTestList = new ArrayList<>();
        alreadySentOffersTestList.add(OfferTestItem.buildTestItem());

        List<AssignedTaskDocument> assignedTaskDocumentsTestList = new ArrayList<>();
        assignedTaskDocumentsTestList.add(AssignedTaskDocumentTestItem.buildTestItem());

        List<InternalProcedureDocument> internalProceduresDocumentsTestList = new ArrayList<>();
        internalProceduresDocumentsTestList.add(InternalProcedureDocumentTestItem.buildTestItem());


        SalesTask testItem = new SalesTask();
        testItem.setId(1L);
        testItem.setVersion(1);
        testItem.setTaskEstablishedDate(DateFormatter.fromStringToDate("10-12-2020T09:12:45"));
        testItem.setLastProgressDate(DateFormatter.fromStringToDate("10-12-2020T09:30:56"));
        testItem.setCompany(CompanyTestItem.buildTestItem());
        testItem.setContactPersonsList(contactPersonTestItemList);
        testItem.setMainSalesMan(SalesManTestItem.buildTestItemNo1());
        testItem.setSupportingSalesTeam(supportingSalesTeamList);
        testItem.setDiscussedProducts(discussedProductsTestList);
        testItem.setProgressList(progressTestList);
        testItem.setCurrentTaskValue(BigDecimal.valueOf(250000));
        testItem.setChanceOfPositiveFinishingTask(0.45);
        testItem.setEstimatedDateOfFinishingTask(DateFormatter.fromStringToDate("30-12-2020T13:00:00"));
        testItem.setAlreadySentOffersList(alreadySentOffersTestList);
        testItem.setAssignedTaskDocumentsList(assignedTaskDocumentsTestList);
        testItem.setInternalProceduresDocumentsList(internalProceduresDocumentsTestList);
        return testItem;
    }

}

我的测试用例是：

我在堆栈跟踪中看到了my MockHttpServletResponse，在那里我可以找到“TaskEstablishedDate”：“2020-12-10t09:12:45.000+00:00”。此外，如果我复制整个响应并将其传递到https://jsonformatter.curiousconcept.com/中，验证将毫无问题地通过。

MockHttpServletResponse:
           Status = 201
    Error message = null
          Headers = [Content-Type:"application/json"]
     Content type = application/json
             Body = {"id":1,"version":1,"taskEstablishedDate":"2020-12-10T09:12:45.000+00:00","lastProgressDate":"2020-12-10T09:30:56.000+00:00", (...) }
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

package com.jmdev.storycrm.domain.company;

import com.jmdev.storycrm.utils.JSONFormatter;
import lombok.Getter;
import lombok.Setter;
import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
@Getter
@Setter
public class Company {

    @Id
    private Long id;
    private String name;
    private Long nipNumber;
    private Address address;

    @Override
    public String toString() {
        return JSONFormatter.useGSON(this);
    }   
}

package com.jmdev.storycrm.utils;

public class JSONFormatter {

    public static String useGSON(Object object){
        return new com.google.gson.Gson().toJson(object);
    }
}

但是我得到了两个值完全相同的java.lang.AssertionError.

java.lang.AssertionError: JSON path "$.company" (...)
Expected :{"id":1,"name":"TestCompanyName","nipNumber":345353534354335,"address":{"id":1,"voivodeship":"Region name","postalCode":"99-000","city":"My City name","street":"Main Street name","fullBiuldingNumber":"100","flatNumber":1}}
Actual   :{"id":1,"name":"TestCompanyName","nipNumber":345353534354335,"address":{"id":1,"voivodeship":"Region name","postalCode":"99-000","city":"My City name","street":"Main Street name","fullBiuldingNumber":"100","flatNumber":1}} 

Answer 1

您需要向ObjectMapper注册JavaTimeModule。
您可以注册JavaTimeModule如下所示。

ObjectMapper objectMapper = new ObjectMapper().registerModule(new JavaTimeModule());

然后使用相同的objectMapper创建json字符串

String newSalesTaskJSON = objectMapper.writeValueAsString(newSalesTask);

javatimemodule来自com.fasterxml.jackson.datatype.jsr310.javatimemodule

.andExpect(jsonPath("$.taskEstablishedDate").value(SalesTaskTestItem.buildTestItem().getTaskEstablishedDate().toString()))
.andExpect(jsonPath("$.lastProgressDate").value(SalesTaskTestItem.buildTestItem().getLastProgressDate().toString()))
.andExpect(jsonPath("$.estimatedDateOfFinishingTask").value(SalesTaskTestItem.buildTestItem().getEstimatedDateOfFinishingTask().toString()))
