PowerMockito (with Mockito) failing with ExceptionInInitializerError

We are using Powermockito with Mockito to mock some static classes. There seems to be java.lang.ExceptionInInitializerError thrown every time.
Can you help me identify where the problem is?
Java class under test
package com.myproject.myproduct.search.domain;
import org.elasticsearch.index.query.MultiMatchQueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
public class MyQueryBuilder {
public MultiMatchQueryBuilder getMultiMatchQueryBuilder() {
MultiMatchQueryBuilder builder = QueryBuilders.multiMatchQuery("term", "field1");
builder.field("field1",200.9f);
return builder;
}
}
Junit test with Powermock runner
package com.myproject.myproduct.search.domain;
import org.elasticsearch.index.query.MultiMatchQueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
#RunWith(PowerMockRunner.class)
#PrepareForTest(QueryBuilders.class)
public class MyQueryBuilderTest {
private MyQueryBuilder myQueryBuilder;
#Test
public void test() {
PowerMockito.mockStatic(QueryBuilders.class);
MultiMatchQueryBuilder builder = PowerMockito.mock(MultiMatchQueryBuilder.class);
}
}
That's it. The test code does not work as soon as I try to mock
MultiMatchQueryBuilder.
This is the Exception:

org.elasticsearch.Build.(Build.java:47) ... 41 more
Process finished with exit code 255
Note:
The source code of actual underlying elasticsearch classes can be found here
https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/index/query/QueryBuilders.java
and
https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/index/query/MultiMatchQueryBuilder.java

When calling with mocks org.elasticsearch.Build#getElasticsearchCodebase
Build.class.getProtectionDomain().getCodeSource().getLocation()
returns null because the code has no location (Dynamic method generated by cglib.)
So when initializing org.elasticsearch.Build during your mock code using
final URL url = getElasticsearchCodebase(); // url is null
final String urlStr = url.toString(); // null pointer exception.
Of course, the mock will not success and throw ExceptionInInitializerError which indicates an exception occurred during evaluation of a static initializer or the initializer for a static variable.
You can easily reproduce this exception using following code:
#RunWith(PowerMockRunner.class)
#PrepareForTest({QueryBuilders.class})
public class MyQueryBuilderTest {
#Test
public void test() {
final Build current = Build.CURRENT;
}
}

So, what am I doing wrong?

You didn't defined any strategy to your generated id for message.
By default, Hibernate will check on your database to find any sequence or strategy to generate values. Try this :
#GeneratedValue(strategy = GenerationType.IDENTITY)

SSLContext mock not behaving as expected

I've the following simple class:
import javax.net.ssl.SSLContext;
public class AClass {
public void someMethod() throws Exception {
SSLContext context = SSLContext.getInstance("SSL");
context.init(null, null, null);
}
}
And its JUnit:
import javax.net.ssl.SSLContext;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
#RunWith(PowerMockRunner.class)
#PrepareForTest({ SSLContext.class })
public class ATest {
#Test
public void testSomeMethod() throws Exception {
PowerMockito.mockStatic(SSLContext.class);
SSLContext context = Mockito.mock(SSLContext.class);
Mockito.when(context.getInstance("SSL")).thenReturn(context);
new AClass().someMethod();
}
}
The JUnit fails with the following stack trace:

The stack trace points to the line with context.init(null, null, null); having a null pointer. However when I debug (in Eclipse), I can clearly see that the value of the context variable is a Mock for SSLContext, hashCode: 1857173583. If a mock, then a void method like init() shouldn't do anything. So, why is it throwing a NullPointerException?

Looking at the API and decompiled signature for the init method which throws the NPE, it shows as final, which basic Mockito.mock() can not handle.
On the other hand, the javadoc for PowerMockito.mock() reads:
org.powermock.api.mockito.PowerMockito
public static T mock(Class type)
Creates a mock object that supports mocking of final and native methods.
Type Parameters:
    T - the type of the mock object
Parameters:
    type - the type of the mock object
Returns:
    the mock object.
So, changing a bit your test should make it work:
#RunWith(PowerMockRunner.class)
#PrepareForTest({SSLContext.class})
public class ATest {
#Test
public void testSomeMethod() throws Exception {
// create the mock to return by getInstance()
SSLContext context = PowerMockito.mock(SSLContext.class);
// mock the static method getInstance() to return above created mock context
PowerMockito.mockStatic(SSLContext.class);
Mockito.when(SSLContext.getInstance("SSL")).thenReturn(context);
// invoke the object under test
new AClass().someMethod();
//TODO - add verifications / assertions
}
}
Update:
Since you're running the test with the PowerMockRunner, you can also replace
SSLContext context = PowerMockito.mock(SSLContext.class);
with a field
#Mock
private SSLContext context;
which will also be handled by PowerMock (or use MockitoJUnitRunner if you just need basic mockito)

java.lang.NoClassDefFoundError: Could not initialize class Hibernate.util.HibernateUtil

The following is my HibernateUtil class:
package Hibernate.util;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.SessionFactory;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from standard (hibernate.cfg.xml)
// config file.
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Log the exception.
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
My controller:
package Controllers;
import DAOImpl.ProductDAOImpl;
import Entities.Product;
import java.sql.SQLException;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class ProductController {
#RequestMapping("/products.htm")
public String getAllProducts() throws SQLException
{
ProductDAOImpl mapping = new ProductDAOImpl();
Product p = new Product();
p.setCost(1000);
p.setName("Саморезы");
mapping.addProduct(p);
return "index";
}
}
But when I run web-app I have excpetion:
java.lang.NoClassDefFoundError: Could not initialize class Hibernate.util.HibernateUtil
DAOImpl.ProductDAOImpl.addProduct(ProductDAOImpl.java:24)

Any Idea?
Might HibernateUtil must be registered in any place?

i think you don't have mysql-connector.jar in your Classpath

This class first of all must be on your classpath. And then make sure that ProductDAOImpl ge the sessionFactory(to eventually provide the session) via HibernateUtil.getSessionFactory().
You are anyway free to define this class as a bean in you application context if you like to do so.

Casting Error related to XmlBeanFactory

When trying to run the Junit Test I got this error. This line :
AppConfig.getGatewayConfigurations().getURL();
is working fine on some places. Also I have no problem related to the path of XML File. And the class GatewayConfigurations is built well and its attributes assigned well in bean configuration file !
Here is the trace
java.lang.ClassCastException: org.springframework.beans.factory.xml.XmlBeanFactory cannot be cast to com.me.vpc.configurations.GatewayConfigurations

PaymentQueryStringBuilderThirdPartyTest Class

AppConfig Class
public class AppConfig {
/**
* Default xml configurations file
*/
private final static String APP_CONFIG_FILE = "vpc-configurations.xml";
/**
* Load gateway configurations
* #return GatwayConfigurations object
*/
public static GatewayConfigurations getGatewayConfigurations(){
return (GatewayConfigurations)getBeans();
}
/**
* Get the desired configuration bean
* #param beanName
* #return BeanFactory object
*/
private static BeanFactory getBeans()
{
return new XmlBeanFactory(new FileSystemResource(APP_CONFIG_FILE));
}
}

Looking at the API for XmlBeanFactory, I can't see how it could be cast to com.me.vpc.configurations.GatewayConfigurations (not surprisingly because you have created that class / interface).
getBeans() returns a XmlBeanFactory, and getGatewayConfigurations() casts that to GatewayConfigurations. This will never work.
