PowerMockito not working : -java.lang.NoClassDefFoundError: org/mockito/internal/creation/CglibMockMaker

Question

我正在尝试使用 powermockito 模拟 CouchbaseCluster.create() 的静态方法。这是我的测试 class.

@PrepareForTest(CouchbaseCluster.class)
public class IAMKafkaConsumerTest extends PowerMockTestCase {
    
    private IAMKafkaConsumer iamKafkaConsumer;
    private CouchbaseCluster mockCouchbaseCluster;
    private Bucket mockBucket;
    
    @ObjectFactory
    public IObjectFactory getObjectFactory() {
        return new org.powermock.modules.testng.PowerMockObjectFactory();
    }

    @Test
    public void happyPath()
    {
        PowerMockito.mockStatic(CouchbaseCluster.class);
       
    }
    
}

我的项目pom包括以下依赖：

            <groupId>cglib</groupId>
            <artifactId>cglib</artifactId>
            <scope>test</scope>

            <artifactId>testng</artifactId>
            <scope>test</scope>
        </dependency>

当我运行通过 TestNG 框架进行测试时，我收到此错误日志。

Answer 1

事实证明，PowerMockito 1.5.X 版本在与 mockito 1.10.9 一起使用时损坏

因此将版本更改为 1。6.X 对我有用。这 link 帮助了我。

Answer 2

除了 Puneet 的回答，你的项目中总是有可能有多个版本的 powermock lib，尤其是当它很大的时候。在我的例子中，我通过项目文件搜索 'powermock' 关键字并找到 powermock-mockito-release-full-1.6.1-full.jar 和 powermock-api-mockito-1.7.0.jar，都有PowerMockMakerclass。因此，删除不兼容的 1.6.1 版本解决了这个问题。
