java.lang.NoClassDefFoundError : Could not initialize class org. mockito.internal.util.MockUtil

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，并没有extends 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

这是一个defect in Mockito当上下文类加载器与用于加载 PowerMock 和 Mockito 的不同时加载插件。

它可以在 Mockito 2 中修复，但正如评论中提到的那样

Not sure we have the build infrastructure to backport the fix on 1.x

对于 Mockito 1，无法提供修复，因此我在 PowerMock 中进行了修复，修复将包含在下一个 PowerMock 版本中(PowerMock 1.6.5)。
