java.lang.NoSuchMethodError：org.mockito.Mockito.framework（）Lorg / mockito / MockitoFramework

Question

我一直面临着一个特殊的问题。基本上，当我正常运行Mockito测试（即“以Junit测试运行”）时，会出现以下错误。有人可以帮我解决我的错误吗？

收到错误：

测试类别：

public class ListTest {
    @Test
    public void letsMockListSize() {
        List<?> list= mock(List.class);
        when(list.size()).thenReturn(2);
        assertEquals(2, list.size());
    }
}

Answer 1

如果删除PowerMock依赖项，该示例将起作用。问题是所使用的Mockito和PowerMock的版本彼此不兼容。对于PowerMock 2.x，您至少需要Mockito 2.8.9+。 PowerMock提供了compatibility list，它显示了哪个版本的PowerMock与哪个版本的Mockito兼容。修复版本以使其相互兼容，您的示例将开始工作。
