java.lang.NoClassDefFoundError: 无法初始化 class org.mockito.inte

Question

我想用testng + powermock + spring来运行测试代码，我的jar版本是：

powermock = 1.6.2
powermock-module-testng = 1.6.2 
mockito = 1.10.19
testng = 6.8.7
spring = 4.1.1.RELEASE
JDK = 1.8.0

而我的测试代码如下，并且不扩展AutoBaseTest，可以正常运行，AutoBaseTest包含@ContextConfiguration（locations={"/test/resources/applicationContext-test.xml"}）

    @PrepareForTest({test.class}) 

  public class mockTest extends AutoBaseTest {
    @ObjectFactory
    public IObjectFactory getObjectFactory() {
        return new PowerMockObjectFactory();
    }

    @Test
    public final void test() throws Exception  {
        ......
    }
    }

Answer 1

这是Mockito加载插件

的一个缺陷，当上下文类加载器与用于加载PowerMock和Mockito的加载器不同时。

它可以在 Mockito 2 中修复，但正如评论中提到的

不确定我们是否有构建基础结构来向后移植 1.x 上的修复程序

对于 Mockito 1，修复无法交付，所以我在 PowerMock 中修复，修复将包含在下一个 PowerMock 版本（PowerMock 1.6.5）中。

Answer 2

我遇到了同样的问题。这对我有帮助在虚拟机选项中的配置下添加 JMockit.Jar 位置，如下所示：

javaagent：C：/.../.../jmockit.jar
