PowerMock will not work with JAXB Unmarshal

Question

I'm creating a test case wherein, I input xml and unmarshal it to procced with processing. I'm trying to use PowerMock and I keep getting

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.xxxxxxx.org/xxxxx/xx/xx", local:"Element"). Expected elements are <{}NotifRQ>,<{http://www.xxxxxxx.org/xxxxx/xx/xx}NotifRS>,etc

I unmarshal it in this Fashion:

JAXBContext jaxbContext = JAXBContext.newInstance(NotifRQ.class);
        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        NotifRQ notifRQ= (NotifRQ) unmarshaller.unmarshal(new File("filename"));

Answer 1

I'm encoutering the same issue about PowerMock failing JAXB unmarshalling XML data from test resources.

I've found this solution to be working : just add this line below @RunWith(PowerMockRunner.class):

@PowerMockIgnore({ "javax.xml.*", "org.xml.sax.*" })

Answer 2

    @RunWith(PowerMockRunner.class)
    @PrepareForTest(Transport.class)
    @PowerMockIgnore({ "javax.xml.*", "org.xml.sax.*" })
    public class AggregateMojoTest {

Great, it fixed my problem !
