java - JUnit 测试用例：参数不同！通缉：
问题描述
我正在尝试使用在控制器级别JUnit为请求编写测试用例。当我这样做时，我遇到了测试用例失败POSTmockitoMockito.verify
AccountMaintenanceSave
public class AccountMaintenanceSave {
public Integer nAccountId;
public String sClientAcctId;
public String sAcctDesc;
public String sLocation;
public Integer nDeptId;
public Integer nAccountCPCMappingid;
public Integer nInvestigatorId;
//Getter and Setter
@Override
public String toString() {
return "AccountMaintenanceSave [nAccountId=" + nAccountId + ", sClientAcctId=" + sClientAcctId + ", sAcctDesc="
+ sAcctDesc + ", sLocation=" + sLocation + ", nDeptId=" + nDeptId + ", nAccountCPCMappingid="
+ nAccountCPCMappingid + ", nInvestigatorId=" + nInvestigatorId + "]";
}
@Override
public boolean equals(Object accountMain) {
if (this == accountMain) return true;
if (accountMain == null || getClass() != accountMain.getClass()) return false;
final AccountMaintenanceSave that = (AccountMaintenanceSave) accountMain;
if (nAccountId != that.nAccountId) return false;
if (nAccountCPCMappingid != that.nAccountCPCMappingid) return false;
if (nDeptId != that.nDeptId) return false;
if (nInvestigatorId != that.nInvestigatorId) return false;
if (sLocation != null ? !sLocation.equals(that.sLocation) : that.sLocation != null) return false;
if (sAcctDesc != null ? !sAcctDesc.equals(that.sAcctDesc) : that.sAcctDesc != null) return false;
return sClientAcctId != null ? sClientAcctId.equals(that.sClientAcctId) : that.sClientAcctId == null;
}
@Override
public int hashCode() {
int result = nAccountId;
result = 31 * result + (sLocation != null ? sLocation.hashCode() : 0);
result = 31 * result + nAccountCPCMappingid;
result = 31 * result + (sAcctDesc != null ? sAcctDesc.hashCode() : 0);
result = 31 * result + nDeptId;
result = 31 * result + (sClientAcctId != null ? sClientAcctId.hashCode() : 0);
result = 31 * result + nInvestigatorId;
return result;
}
}
帐户控制器
@RestController
@RequestMapping("/api.spacestudy.com/SpaceStudy/Admin")

@Autowired
AccountService accService;

AccountMaintenanceSave accountMain = new AccountMaintenanceSave();
accountMain.setnAccountId(65175);
accountMain.setsLocation("B");
accountMain.setnAccountCPCMappingid(8);
accountMain.setsAcctDesc("FY07 GEN GIFTS");
accountMain.setnDeptId(21728);
accountMain.setsClientAcctId("2100012");

Mockito.when(accountService.btnSaveClick(accountMain))

RequestBuilder requestBuilder = MockMvcRequestBuilders
.put("/api.spacestudy.com/SpaceStudy/Admin/Account/saveAttributes").accept(MediaType.APPLICATION_JSON)
.contentType(MediaType.APPLICATION_JSON).content(json);
MvcResult result = mockMvc.perform(requestBuilder).andReturn();
MockHttpServletResponse response = result.getResponse();
assertEquals(HttpStatus.OK.value(), response.getStatus());
Mockito.verify(accountService).btnSaveClick(accountMain).toString();
}
}
堆栈跟踪
Argument(s) are different! Wanted:
accountService.btnSaveClick(
AccountMaintenanceSave [nAccountId=65175, sClientAcctId=2100012, sAcctDesc=FY07 GEN GIFTS, sLocation=B, nDeptId=21728, nAccountCPCMappingid=8, nInvestigatorId=65760]
);
-> at com.spacestudy.AccountControllerTest.btnSaveClickTest(AccountControllerTest.java:71)
Actual invocation has different arguments:
accountService.btnSaveClick(
AccountMaintenanceSave [nAccountId=65175, sClientAcctId=2100012, sAcctDesc=FY07 GEN GIFTS, sLocation=B, nDeptId=21728, nAccountCPCMappingid=8, nInvestigatorId=65760]

解决方案
根据您的equals方法，您似乎正在根据引用相等比较 Objects (boxed primitives) 。无论您是否以及如何使用 Mockito，这都是一个错误。
尽管int可以使用 比较==像这样的原语，但不应将像 Integer 这样的盒装原语与 进行比较==：您可能有两个单独的 Integer 实例，每个实例都表示 integer 3，这样firstInt != secondInt但是firstInt.equals(secondInt)是正确的。这可能导致不一致的行为：Java 机会主义地尝试对文字字符串和小整数使用相同的实例，但您不能依赖这种行为。toString如您所见，这也会导致您的输出相同。
这里最好的答案是使用像 Integer 这样的原语int而不是像 Integer 这样的盒装原语：只要结果总是非空的，你就不会通过存储盒装版本获得任何东西。如果您这样做，那么您当前的equals方法（首先在已删除的答案中通过 glytching 发布）将可以正常工作。
如果您出于某种原因需要使用盒装原语，您应该将它们与它们的equals方法进行比较。
因此，而不是像这样的检查：
if (nAccountId != that.nAccountId) return false;
if (nAccountCPCMappingid != that.nAccountCPCMappingid) return false;
像这样进行检查：
if (!nAccountId.equals(that.nAccountId)) return false;
if (!nAccountCPCMappingid.equals(that.nAccountCPCMappingid)) return false;
请注意，整数字段，如字符串字段，可以是null. 为了防止这种情况发生，您应该null像使用 Strings 一样进行显式检查，或者使用Java 8 中的新Objects.equals方法：
if (!Objects.equals(this.nAccountId, that.nAccountId)) return false;
if (!Objects.equals(this.nAccountCPCMappingid, that.nAccountCPCMappingid)) return false;
