Mocking com.ibm.mq.jms.MQQueueConnectionFactory

[ron.difrango]

I'm attempting to mock com.ibm.mq.jms.MQQueueConnectionFactory and when I do, I get the following error:

java.lang.VerifyError: (class: com/ibm/msg/client/jms/internal/JmsReadablePropertyContextImpl, method: toString signature: ()Ljava/lang/String;) Unable to pop operand off an empty stack

at java.lang.Class.forName0(Native Method)

at com.capitalone.api.commons.web.config.MQAuditSpringConfigTest.testAuditTemplate(MQAuditSpringConfigTest.java:55)

My test starts with:

@RunWith(PowerMockRunner.class)

@MockPolicy(Slf4jMockPolicy.class)

@PrepareForTest({MQAuditSpringConfig.class, MQAuditSpringConfigTest.class, MQConnectionFactory.class,

        MQQueueConnectionFactory.class, JmsJndiConnectionFactoryImpl.class, JmsConnectionFactoryImpl.class,

        JmsPropertyContextImpl.class, JmsReadablePropertyContextImpl.class})

@SuppressStaticInitializationFor({"com.ibm.mq.jms.MQConnectionFactory", "com.ibm.mq.jms.MQQueueConnectionFactory",

        "com.ibm.msg.client.jms.admin.JmsConnectionFactoryImpl",

        "com.ibm.msg.client.jms.admin.JmsJndiConnectionFactoryImpl",

        "com.ibm.msg.client.jms.internal.JmsPropertyContextImpl",

        "com.ibm.msg.client.jms.internal.JmsReadablePropertyContextImpl"})

And then the line in question is:

MQQueueConnectionFactory mqFactory = new MQQueueConnectionFactory();

[ron.difrango]

MQQueueConnectionFactory mqFactory = PowerMockito.mock(MQQueueConnectionFactory.class);

Seems like a complicated test setup. Perhaps you could just use an in-memory JMS provider such as ActiveMQ when you run your tests? Otherwise you could try starting your JVM with "-XX:-UseSplitVerifier".

/Johan

MQQueueConnectionFactory mqFactory = PowerMockito.mock(MQQueueConnectionFactory.class);

Johan,

Unfortunately that is not an option as our production code needs to use IBM MQ and therefore I was trying to build unit tests that we build the classes appropriate, but I wanted to do so via mocks.

I'll try the -XX:-UseSplitVerifier and see if that works.

Thanks,

Ron
