Mockito mock calling real method implementation when attempting to stub package protected method

Question

I\'m trying to stub a method using Mockito 1.8.5, but doing so calls the real method implementation (with \"\" as parm values) which throws an exception.

I disagree with the accepted response.

I think, you have to provide more details on your environment. I can't reproduce your problem. I write the following code in a maven project :

package background.internal; //located in src/main/java

public class FileAttachmentContainer {
    String moveAttachment(String arg1, String arg2, String arg3) {
        throw new IllegalStateException();
    }

    String getPersistedValue(Context context) {
        throw new IllegalStateException();
    }
}

and

package background.internal;

public class AttachmentMoveStep {

    private FileAttachmentContainer file;

    public AttachmentMoveStep(FileAttachmentContainer file) {
        this.file = file;
    }

    public Action advance(double acceleration, Context context) {
        String attachmentValue = file.getPersistedValue(context);
        file.moveAttachment(attachmentValue, "attachment", context.getUserName());
        return Action.done;
    }
}

and the following test pass

package background.internal; //located in src/test/java

import static org.junit.Assert.assertEquals;
import static org.mockito.Matchers.anyString;
import static org.mockito.Mockito.doReturn;
import static org.mockito.Mockito.mock;

import org.junit.Test;

public class MoveStepTest {

    @Test
    public void testMoveUpdate() {
        String returnValue = "value";
        FileAttachmentContainer file = mock(FileAttachmentContainer.class);
        doReturn(returnValue).when(file).moveAttachment(anyString(), anyString(), anyString());
        //this also works
        //when(file.moveAttachment(anyString(), anyString(), anyString())).thenReturn(returnValue);

        AttachmentMoveStep move = new AttachmentMoveStep(file);
        Action moveResult = move.advance(1, mock(Context.class));
        assertEquals(Action.done, moveResult);
    }
}

My project use the following dependencies :

• jdk1.7.0_05
• junit-4.10.jar
• mockito-all-1.9.0.jar
• javassist-3.16.1-GA.jar
• objenesis-1.2.jar
• hamcrest-core-1.1.jar
