在PODAM 7.0.0中创建递归对象时PodamMockeryException

Question

我正在用Mockito和Podam编写一些JUnit测试。很多东西工作正常，但我在一个测试用例中遇到了一个问题，同时生成一个递归对象。

如下代码抛出PodamMockeryException与上manufacturePojo()线podam 7.0.0.RELEASE：

@Test 
public void testDoTest() { 
    PodamFactory podamfactory = new PodamFactoryImpl(); 
    Entity eTest = podamfactory.manufacturePojo(Entity.class); 
    ... 
} 

更多堆栈跟踪和实体如下。

实体是JPA实体，它看起来有点像下面这样：

public class Entity extends AllTheEntities { 
    @Id 
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "DOCUMENT_SEQ") 
    @SequenceGenerator(name = "DOCUMENT_SEQ", sequenceName = "DOCUMENT_SEQ", allocationSize = 1) 
    @Column(name = "DOCUMENT_ID", precision = 19) 
    private long objectId; 
    @Column(name = "NAME") 
    private String name; 

    // bi-directional many-to-one associations 
    @ManyToOne 
    @JoinColumn(name = "FK_STND_MIME_TYPE_ID", nullable = false) 
    private StndMimeTypeEntity stndMimeType; 

    @OneToMany(mappedBy = "document", cascade = CascadeType.REMOVE) 
    private List<FolderThingEntity> FolderThings; 

    @OneToMany(mappedBy = "document", cascade = CascadeType.ALL) 
    private List<FieldData> fieldData; 

    @OneToMany(mappedBy="document") 
    private List<PersonalFormContentEntity> personalFormContents; 

    public Entity() { 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public List<FieldData> getDocumentBindFieldData() { 
     return this.fieldData; 
    } 

    public void setDocumentBindFieldData(
      List<FieldData> fieldData) { 
     this.fieldData = fieldData; 
    } 

    public FieldData addDocumentBindFieldData(
      FieldData fieldData) { 
     getDocumentBindFieldData().add(fieldData); 
     fieldData.setDocument(this); 

     return fieldData; 
    } 

    @Override 
    public String toString() { 
     return "Entity [objectId=" + objectId + ", name=" 
    + name + ", stndMimeType=" + stndMimeType.getStndMimeTypeId() + "]"; 
    } 

    public OfficeActionEntity getForm() { 

     FolderThingEntity fd = getFolderThings().get(0); 

     FolderEntity folderEntity = fd.getFolder(); 

     return folderEntity.getForm(); 

    } 

} 

多一点堆栈跟踪：

Answer 1

我猜FieldData对象包含java.sql.Timestamp或扩展它。后者对其制定者要求非常具体的价值。所以有必要为这个班级量身定制随机值。下面是一个例子，它是如何实现的：

PodamFactory podamFactory = new PodamFactoryImpl(); 
TypeManufacturer<Integer> manufacturer = new IntTypeManufacturerImpl() { 

    @Override 
    public Integer getInteger(AttributeMetadata attributeMetadata) { 

     if (attributeMetadata.getPojoClass() instanceof Timestamp) { 
      return PodamUtils.getIntegerInRange(0, 999999999); 
     } else { 
      return super.getInteger(attributeMetadata); 
     } 
    } 
}; 
podamFactory.getStrategy().addOrReplaceTypeManufacturer(int.class, manufacturer); 

FieldData pojo = podamFactory.manufacturePojo(FieldData.class);
