Question

我正在用Mockito和Podam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，同时生成了一个递归对象。

以下代码在PodamMockeryException行上使用podam 7.0.0.RELEASE抛出manufacturePojo()：

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

更多堆栈跟踪和实体在下面。

实体是JPA实体，它看起来有点像：

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();

    }

}

Answer 1

我猜FieldData对象包含java.sql.Timestamp或扩展它。后者需要非常具体的设置值。因此需要为此类定制的定制随机值。这是一个例子，如何实现：

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);

在PODAM 7.0.0中创建递归对象时出现PodamMockeryException
