ExceptionInInitializerError when mocking org.hibernate.Hibernate.class

[Vanga]

here is my code with imports

import static org.easymock.EasyMock.anyObject;
import static org.powermock.api.easymock.PowerMock.replay;

import org.hibernate.Hibernate;
import org.powermock.api.easymock.PowerMock;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit3.PowerMockSuite;
import junit.framework.TestCase;
import junit.framework.TestSuite;

@PrepareForTest(Hibernate.class)
public class TempTest extends TestCase {

@SuppressWarnings("unchecked")
public static TestSuite suite() throws Exception {
return new PowerMockSuite("Unit tests for " +
TempTest.class.getSimpleName(), TempTest.class);
}

public void testTemp(){
PowerMock.mockStatic(Hibernate.class);
Hibernate.initialize(anyObject());
replay(Hibernate.class);
}
}

Line PowerMock.mockStatic(Hibernate.class); causes
java.lang.ExceptionInInitializerError . Why? I need to mock
Hibernate.initialize(); . Who can help?

Could you please post the stack trance? Maybe you need to suppress a static initializer.

There is something with log4j. Maybe I need to disable it? but how, I can't change code.

Try to add
@PowerMockIgnore("org.apache.commons.logging")

Ok, I'll try tomorrow and say

Hm, it works. But it works, even if I don't mock HIbernate.initialize() at all!! What does this annotation do?

[Илья Иля]

Sorry ) only one Hibernate.initialize() go on success. But others no. So I mock it and it works well now. What about this annotation is?

[Jan Kronquist]

This annotation tells PowerMock not to load classes starting with this
name with PowerMock's classloader. Instead the normal classloader will
be used:
