Unit tests in JUnit failing when I run update/delete commands - spring

Question

I am currently working on an API implementation in Java with spring and hibernate.
I have two tables in my Model package
User and UserDetail which has a OneToMany mapping
#Entity
public class User {
private Long id;
private String userId;
private Set<UserDetail> userDetails;
#OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "user")
public Set<UserDetail> getUserDetails() {
return userDetails;
}
public void setUserDetail(Set<UserDetail> userDetails) {
this.userDetails = userDetails;
}
}
#Entity
public class User {
private Long id;
private String key;
private String value;
private User user;
#ManyToOne
#JoinColumn(name = "USER_ID", nullable = false)
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
My API looks like this
#Transactional(propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)
public void addUserDetail(AddUserDetailRequest request) {
//... adds the user detail for the userId as request.getUserId()
}
#Transactional(propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)
public void deleteUserDetail(DeleteUserDetailRequest request) {
//... deletes a particular value for a user with userId as request.getUserId() and userDetail key as request.getDeleteKey()
}
I have written Junit test cases to test the addition and deletion of UserDetails for a user, My addUserDetail is working as it should, but when I call the delete the changes are not reflected and they fail.
Below is my test case
#Test
public void testDeletUserDetail() throws Exception {
//GIVEN
String userId = client.newUser().call(getCreateUserRequest()).getId();
client.newAddUserDetail().call(getAddUserDetailRequest(userId, "key1", "value1"));
client.newAddUserDetail().call(getAddUserDetailRequest(userId, "key2", "value2"));
//WHEN
client.newDeteteUserDetail().call(getDeleteUserDetailRequest(userId, "key2"));
//THEN
List<UserDetail> userDetails = client.newGetUserDetail().call(getGetUserDetailRequest(userId));
assertEquals(userDetails.size(), 1); // This check fails and says it has a size of 2 instead of 1.
}
I am using HSQL for testing purposes
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="com.iiitd.myAPI.model" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="database" value="HSQL" />
<property name="generateDdl" value="true" />
<property name="showSql" value="false" />
</bean>
</property>
</bean>
<jdbc:embedded-database id="dataSource" type="HSQL" />
I have two implementation for deleteUserDetail and one of them fails.
// This one works in both jUnit and manual testing
#Transactional(propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)
public void deleteUserDetail(DeleteUserDetailRequest request) {
User user = userRepository.findByUserId(request.getUserId());
if(!CollectionUtils.isEmpty(user.getUserDetail())) {
UserDetail toRemove = null;
for(UserDetail userDetail : user.getUserDetail()) {
if(StringUtils.equals(userDetail.getKey(), request.getDeleteKey())) {
toRemove = userDetail;
}
}
Assert.notNull(toRemove, "Detail user doesn't exist.");
user.getUserDetail().remove(toRemove);
userRepository.save(user);
}
}
//This one doesn't and unit tests fails but manual tests are OK
#Transactional(propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)
public void deleteUserDetail(DeleteUserDetailRequest request) {
UserDetail userDetail = userDetailRepository.getUserDetail();
Assert.notNull(userDetail, "Detail doesn't exists");
userDetailRepository.delete(userDetail);
}
All the repositories extends JpaRepository
Could anyone explain how to circumvent this issue ?
Any help would be appreciated.
