小松树易失

我正在使用EasyMock为我的21点游戏编写单元测试。 java.lang.IllegalArgumentException: Cannot subclass final class class com.blackjack.game.cards.Card 错误。

不过,我觉得我做得对。 这是我的测试类:

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.easymock.EasyMock;
import org.easymock.EasyMockRunner;
import org.easymock.EasyMockSupport;

@RunWith(EasyMockRunner.class)
public class handTest extends EasyMockSupport{
    private Hand hand;
    private Card seven, nine, ten, jack, ace;

    @Before
    public void setUp() throws Exception
    {
        seven = EasyMock.createNiceMock(Card.class);
        EasyMock.expect(seven.getValue()).andStubReturn(7);
        EasyMock.expect(seven.toString()).andStubReturn("seven value: 7");

    }

    @Test
    public void testTotalHandValueByAddingNumbers() {
        replayAll();
        hand.addCard(seven);

        assertEquals(27, hand.getTotal());


    }
}

编辑:我的类路径中同时有Objenesis和cglib。

谢谢
