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

Question

我一直面临一个奇怪的问题。基本上，当我正常运行 Mockito 测试时，即“作为 Junit 测试运行”时，它给了我以下错误。有人可以帮助我请问我的错误是什么？

收到的错误:

    java.lang.NoSuchMethodError: org.mockito.Mockito.framework()Lorg/mockito/MockitoFramework;
        at org.powermock.api.mockito.mockmaker.MockMakerLoader.doLoad(MockMakerLoader.java:45)

测试类:

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

Answer 1

如果您删除 PowerMock 依赖项，则该示例有效。问题是使用的 Mockito 和 PowerMock 版本彼此不兼容。对于 PowerMock 2.x，您至少需要 Mockito 2.8.9+。 PowerMock 提供了一个 compatibility list显示什么版本的 PowerMock 与什么版本的 Mockito 兼容。修复版本以相互兼容，您的示例将开始工作。
