Java PowerMock-mockStatic没有'；t捕获模拟的静态void方法调用

我尝试在Mockito上使用PowerMock模拟静态void方法，但效果不太好

我的示例代码：

BlackTempleTest.java

package com;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

import com.BlackTempleTest.Illidan;

@RunWith(PowerMockRunner.class)
@PrepareForTest({ Illidan.class, EvilBrother.class })
public class BlackTempleTest {

    Answer<Object> defaultAnswer = new Answer<Object>() {
        @Override
        public Object answer(InvocationOnMock invocation) throws Throwable {
            System.out.println("Haha!");
            return null;
        }
    };

    @Test(expected = AssertionError.class)
    public void testIllidanFight() throws Exception {
        Illidan.startFight();
    }

    @Test
    public void testCheatOnIllidanFight() throws Exception {
        PowerMockito.mockStatic(Illidan.class, defaultAnswer);

        Illidan.startFight();
    }

    @Test(expected = AssertionError.class)
    public void testEvilBrotherFight() throws Exception {
        EvilBrother.startFight();
    }

    // dont work
    @Test
    public void testCheatOnEvilBrotherFight() throws Exception {
        PowerMockito.mockStatic(EvilBrother.class, defaultAnswer);

        EvilBrother.startFight();
    }

    static class Illidan {
        static void startFight() {
            Assert.fail("You are not prepared!");
        }
    }
}

我的问题是，使用@PrepareForest和PowerMockito.mockStatic的组合按预期模拟嵌套类，但是如果该类在其自己的类文件中，这些语句就不起作用

a如何修复此测试

编辑：

可以通过Powermock通过管道传输错误调用，但是会执行Assert.fail

解决方案是，你必须模仿伊利丹而不是邪恶兄弟，即使你调用邪恶兄弟.startFight，因为方法是继承的

@Test
public void testCheatOnEvilBrotherFight() throws Exception {
    PowerMockito.mockStatic(Illidan.class, defaultAnswer);

    EvilBrother.startFight();
}

我有相同的错误。但是我的模拟类没有从另一个类继承。请发布您的代码。没有你，我无法帮助你。我解决了我的问题。谢谢你的回复。在某些情况下，单个测试框架并不包括您需要的所有必要工具。这就是为什么在上面的示例中使用PowerMock的原因。
