Re: [powermock] java.lang.VerifyError: Wrong return type in function

[Johan Haleby]

Hi, 

What JDK version are you using? What rule implementation are you using? (java agent or classloader based?)

Regards,

Hello everyone,

I am using Powermockito 1.5 (with mockito 1.9.5), using junit4-rule-1.5.  I'm mocking a static method which is checked through production code called indirectly by the test.  However, when I try to set up the test, I need to create a JMenu object - however, this throws a VerifyError - I think because the method it is complaining about is static - but I am not trying to (nor want to) mock it.

My test class looks basically like this:

@PrepareForTest( {MyClassWithStaticMethod.class} )

public class tester

{

@Rule

        public PowerMockRule rule = new PowerMockRule();

@Test

public void test()

{  

 mockStatic( MyClassWithStaticMethod .class);

 when( MyClassWithStaticMethod.staticMethod(true)).thenReturn(true);

 JMenuItem menuthing = new JMenu("hello");

                 

                 // the rest of the test

        }

}

and I get this error message when I run it....

java.lang.VerifyError: (class: javax/swing/plaf/metal/MetalLookAndFeel, method: getLayoutStyle signature: ()Ljavax/swing/LayoutStyle;) Wrong return type in function

Any ideas what I am doing wrong?

Thanks,

James.

Hi,

Currently using 1.6.0_30 and using classloading objenesis.  I couldn't get the xstream to work either.

Cheers,

James.

They are all experimental, I would try the Java agent based rule and see if that works.

Ah, excellent, yes, changed to the agent and it all works perfectly now, thank you very much!

Cheers,

James.
