是否有办法模拟密封接口?
原标题：Is there any way to mock a sealed interface?

今天,我为“java 16”预约创建了一个小型测试项目。 我创建了一个密封的接口和最后执行。

我想知道,是否有任何途径能够改变封闭的接口,以便我能够测试使用密封接口的安装。

package gluestick;

public sealed interface Test permits TestImpl {
    int doIt();
}

package gluestick;

public final class TestImpl implements Test {
    @Override
    public int doIt() {
        return 0;
    }
}

import org.junit.jupiter.api.Test;
import org.mockito.Mockito;

public class MyTest {

    @Test
    public void test() {
        Mockito.mock(gluestick.Test.class);
    }
}

然而,所有这些都造成了 j。 无法执行密封等级。

org.mockito.exceptions.base.MockitoException: 
Mockito cannot mock this class: interface gluestick.Test.

Mockito can only mock non-private & non-final classes.
If you re not sure why you re getting this error, please report to the mailing list.

不可能 mo一个密封的舱。

如果你认为自己有能力这样做,那么你就应当怀疑你是否应该完全使用密封的舱。

封印班的实际使用量为小的<>>,你可能不需要。

在奥赫里,你发现各种原因之一,即穿制服的课堂,是你可能永远不会在没有非常好的理由的情况下使用的东西。

海运班次应为always抽象。

Mock 是已知的,不是密封的。
