java - 如何使用 mockito 和 testNg 测试枚举中的默认值

Question

我有一个像这样的第三方枚举类:

package se.api;
public enum InvestigationResultStatus {
  PENDING("PendingResult.rr"),
  NEW("NewResult.rr"),
  MODIFIED("ModifiedResult.rr"),
  FINAL("FinalResult.rr"),
  PRELIMINARY("PreliminaryResult.rr"),
  ADDITIONAL("AdditionalResult.rr"),
  REJECTED("RejectedResult.rr"),
  COMPLETE("Path.Results.InvestigationInformation.Complete"),
  UNDEFINED("");

  private final String languageKey;

  private InvestigationResultStatus(String languageKey) {
    this.languageKey = languageKey;
  }

  public String getLanguageKey() {
    return this.languageKey;
  }
}

在我的代码中，我为这个类创建了枚举

package se.dto;
public enum InvestigationResultStatus
{
   PENDING,
   NEW,
   MODIFIED,
   FINAL,
   PRELIMINARY,
   ADDITIONAL,
   REJECTED,
   UNDEFINED
}

为了将这些 api 枚举映射到我的枚举，我创建了枚举映射器:

package se.mapper;

import se.dto.InvestigationResultStatus;

public class InvestigationResultStatusMapper
{
  public InvestigationResultStatus mapOmResultStatusToNovaResultStatus(final se.api.InvestigationResultStatus investigationResultStatus){
    switch (investigationResultStatus){
      case PENDING:
        return InvestigationResultStatus.PENDING;
      case NEW:
        return InvestigationResultStatus.NEW;
      case MODIFIED:
        return InvestigationResultStatus.MODIFIED;
      case FINAL:
        return InvestigationResultStatus.FINAL;
      case PRELIMINARY:
        return InvestigationResultStatus.PRELIMINARY;
      case ADDITIONAL:
        return InvestigationResultStatus.ADDITIONAL;
      case REJECTED:
        return InvestigationResultStatus.REJECTED;
      case UNDEFINED:
        return InvestigationResultStatus.UNDEFINED;
      default:
        throw new IllegalArgumentException("Unknown InvestigationResultStatus: " + investigationResultStatus);
    }
  }
}

现在我想测试 InvestigationResultStatusMapper 类的默认案例路径并抛出 IllegalArgumentException。我搜索并以多种方式尝试它。但是大多数示例都在使用 powermockito。但是我想要 mackito 和 testNg。我如何测试它。我用这个尝试它，

@Test(expectedExceptions = { IllegalArgumentException.class })
  public void testMapOmResultStatusToNovaResultStatus_whenHaveDefaultValue_thenThrowIllegalArgumentException()
  {
    se.api.InvestigationResultStatus investigationResultStatusNewEnum = mock(se.api.InvestigationResultStatus.class);
    Whitebox.setInternalState(investigationResultStatusNewEnum, "name", "DEFAULT");
    Whitebox.setInternalState(investigationResultStatusNewEnum, "ordinal", "DefaultResult.rr");

    se.api.InvestigationResultStatus investigationResultStatusCosmic = mock(se.api.InvestigationResultStatus.class);

    when(investigationResultStatusCosmic.values()).thenReturn(
        new se.api.InvestigationResultStatus[] { InvestigationResultStatus.PENDING, InvestigationResultStatus.NEW,
            se.api.InvestigationResultStatus.MODIFIED, InvestigationResultStatus.FINAL, InvestigationResultStatus.PRELIMINARY,
            se.api.InvestigationResultStatus.ADDITIONAL, InvestigationResultStatus.REJECTED,
            se.api.InvestigationResultStatus.COMPLETE, InvestigationResultStatus.UNDEFINED, investigationResultStatusNewEnum });

    investigationResultStatusMapper.mapOmResultStatusToNovaResultStatus(investigationResultStatusNewEnum);
  }

您可以直接创建实例以避免模拟。

@Test(expectedExceptions = { IllegalArgumentException.class })
public void testMapOmResultStatusToNovaResultStatus_whenHaveDefaultValue_thenThrowIllegalArgumentException()
{

  InvestigationResultStatus investigation = new InvestigationResultStatus();
  investigation.mapOmResultStatusToNovaResultStatus(-10000);
   ....

}
