I have two entity.
one is Profile:
package ry.enstudy.entity;
import java.io.Serializable;
import java.util.List;
import javax.jdo.annotations.*;
import com.google.appengine.api.users.User;
@PersistenceCapable(identityType = IdentityType.APPLICATION)
@Queries(value = {...@query(name = "findByUser", value = "select from
Profile where user == :user")})
public class Profile implements Serializable {
private static final long serialVersionUID = -5700704235163464277L;
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = "datanucleus", key = "gae.encoded-pk", value
= "true")
private String id;
@Persistent
private User user;
@Persistent
private String test;
@Order(extensions = @Extension(vendorName = "datanucleus", key =
"list-ordering", value = "createDate asc"))
@Persistent(defaultFetchGroup = "true")
private List<Sentence> sentences;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public void setSentences(List<Sentence> sentences) {
this.sentences = sentences;
}
public List<Sentence> getSentences() {
return sentences;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getTest() {
return test;
}
public void setTest(String test) {
this.test = test;
}
}
the other one is Sentence
package ry.enstudy.entity;
import java.io.Serializable;
import java.util.Date;
import javax.jdo.annotations.Extension;
import javax.jdo.annotations.IdGeneratorStrategy;
import javax.jdo.annotations.IdentityType;
import javax.jdo.annotations.PersistenceCapable;
import javax.jdo.annotations.Persistent;
import javax.jdo.annotations.PrimaryKey;
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Sentence implements Serializable {
private static final long serialVersionUID = -1183409823615443436L;
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName = "datanucleus", key = "gae.encoded-pk", value
= "true")
private String id;
@Persistent
private String content;
@Persistent
private int rememberState;
@Persistent
private Date createDate;
@Persistent
private Profile profile;
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Date getCreateDate() {
return createDate;
}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
public int getRememberState() {
return rememberState;
}
public void setRememberState(int rememberState) {
this.rememberState = rememberState;
}
public Profile getProfile() {
return profile;
}
public void setProfile(Profile profile) {
this.profile = profile;
}
}
Profile own many Sentence.
This is my unit test:
package ry.enstudy.actions;

public class RememberTaskActionTest{
private static final PersistenceManagerFactory pmfInstance =

.getPersistenceManagerFactory("transactions-optional");
@Before
public void beforeClass() {

ApiProxy.setDelegate(new ApiProxyLocalImpl(new File(".")) {

ApiProxy.setDelegate(null);
ApiProxy.setEnvironmentForCurrentThread(null);
}
@Test
public void TestAddTask() throws Exception {
PersistenceManager pm = pmfInstance.getPersistenceManager();
pm.currentTransaction().begin();
Profile profile = new Profile();
profile.setTest("ssss");
pm.makePersistent(profile);
Sentence sentence = new Sentence();
sentence.setContent("This is test.");
sentence.setCreateDate(Calendar.getInstance().getTime());
profile.getSentences().add(sentence);
Profile p = (Profile) pm.getObjectById(Profile.class,
profile.getId
());
assertEquals(1, p.getSentences().size()); // pass
pm.currentTransaction().commit();
pm.close();
pm = pmfInstance.getPersistenceManager();
pm.currentTransaction().begin();
Sentence s = pm.getObjectById(Sentence.class, sentence.getId());
assertEquals(s.getContent(), "This is test."); // pass
pm.currentTransaction().commit();
pm.close();
pm = pmfInstance.getPersistenceManager();
pm.currentTransaction().begin();
Profile p2 = (Profile) pm.getObjectById(Profile.class,
profile.getId
());
assertEquals(1, p2.getSentences().size());// fail
pm.currentTransaction().commit();
pm.close();
}
}
Any one could help me, why the third assert fail? thank you
