I'm getting an exception when using PowerMockRule for a test class extending from AbstractTransactionalJUnit4SpringContextTests.

This test works:

@ContextConfiguration(locations="/meta-inf/springtest/applicationContext.xml")
@RunWith(SpringJUnit4ClassRunner.class)
@PrepareForTest({Utils2.class})
public class TempTest {
@rule
public PowerMockRule rule = new PowerMockRule ();

@Autowired
private Utils2 utils;

@Test
public void say() {
    Assert.assertNotNull(this.utils);
}

}

This doesn't:

@ContextConfiguration(locations="/meta-inf/springtest/applicationContext.xml")
@PrepareForTest({Utils2.class})
public class TempTest extends AbstractTransactionalJUnit4SpringContextTests {

@Rule         
public PowerMockRule rule = new PowerMockRule ();

@Autowired
private Utils2 utils;

//@Autowired
// private NeighborhoodService neighborhoodService;

@Test
public void say() {
    // Assert.assertNotNull(this.neighborhoodService);
    Assert.assertNotNull(this.utils);
}

}

I got an exception with this stack trace:

I'm using PowerMock 1.4.10, Javassist 3.15.0.GA, and XStream 1.4.1 on Windows 7.

I also tried not extending AbstractTransactionalJUnit4SpringContextTests, but autowiring an entity object. I got a similar exception on not finding a proxy class (CGLIB enhanced).

It looks like PowerMockRule doesn't work with proxy objects.

Thanks!

Thanks for reporting. The behavior of the PowerMockRule is quite complex and it's hard to cover all the corner-cases. Perhaps what you need to do is to ignore some packages for test that you suspect are creating the proxies (if possible). If not I'm afraid you would have to help us out a bit and dig into the PowerMock code and try to find a solution to the problem.

Hi,

I have this issue too and i understand why:

At some moment PowerMock serialize the test class and Xstream cannot serialize the ApplicationContext class from Spring(Proxy classe too and some others from my experience.)

I try to make a patch but i do not understand why PowerMock deep clone some classes. If you can explain me that, i think i could find a patch.

Thanks for your help.

Hi Again,

After understood that the problem is about Serialization. I add the key-word transient on attribute applicationContext and I run again the test to discover that my test case is executed from the tests class cloned and by consequence attribute applicationContext is null.

Can you explain me why tests cases is executed from the tests class cloned ?

Thanks in advance.

You can try out the Javaagent based PowerMockRule and see if it makes any difference.

Hi GuitarGice,

This week i try to use the powermockagent ( https://code.google.com/p/powermock/wiki/PowerMockAgent ) and it solved my problem.

Indeed my issue was that serialization has tried to serialize a huge object in order to change where my huge instance is loaded. With powermockagent no more serialization is needed by powermock to inject some source code and do its job.

The only constraint to use this agent is its demand some configuration. And if you use eclipse + maven you have to configured eclipse to use the agent and maven too. if you forgot one of them some tests will fail.

In my case i'm using:

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration({ "classpath:/WEB-INF/servlet.xml", "classpath:/WEB-INF/security.xml" })
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
@PrepareForTest({ AccessLoginWebDatabase.class, AccessLoginWebDatabase.class })
public class AuthenticationControllerTestCase
