PowerMockito (with Mockito) failing with ExceptionInInitializerError

We are using Powermockito with Mockito to mock some static classes. There seems to be java.lang.ExceptionInInitializerError thrown every time.
Can you help me identify where the problem is?
Java class under test
package com.myproject.myproduct.search.domain;
import org.elasticsearch.index.query.MultiMatchQueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
public class MyQueryBuilder {
public MultiMatchQueryBuilder getMultiMatchQueryBuilder() {
MultiMatchQueryBuilder builder = QueryBuilders.multiMatchQuery("term", "field1");
builder.field("field1",200.9f);
return builder;
}
}
Junit test with Powermock runner
package com.myproject.myproduct.search.domain;
import org.elasticsearch.index.query.MultiMatchQueryBuilder;
import org.elasticsearch.index.query.QueryBuilders;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
#RunWith(PowerMockRunner.class)
#PrepareForTest(QueryBuilders.class)
public class MyQueryBuilderTest {
private MyQueryBuilder myQueryBuilder;
#Test
public void test() {
PowerMockito.mockStatic(QueryBuilders.class);
MultiMatchQueryBuilder builder = PowerMockito.mock(MultiMatchQueryBuilder.class);
}
}
That's it. The test code does not work as soon as I try to mock
MultiMatchQueryBuilder.
This is the Exception:

Caused by: java.lang.NullPointerException at
org.elasticsearch.Build.(Build.java:47) ... 41 more
Process finished with exit code 255
Note:
The source code of actual underlying elasticsearch classes can be found here
https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/index/query/QueryBuilders.java
and
https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/index/query/MultiMatchQueryBuilder.java

When calling with mocks org.elasticsearch.Build#getElasticsearchCodebase
Build.class.getProtectionDomain().getCodeSource().getLocation()
returns null because the code has no location (Dynamic method generated by cglib.)
So when initializing org.elasticsearch.Build during your mock code using
final URL url = getElasticsearchCodebase(); // url is null
final String urlStr = url.toString(); // null pointer exception.
Of course, the mock will not success and throw ExceptionInInitializerError which indicates an exception occurred during evaluation of a static initializer or the initializer for a static variable.
You can easily reproduce this exception using following code:
#RunWith(PowerMockRunner.class)
#PrepareForTest({QueryBuilders.class})
public class MyQueryBuilderTest {
#Test
public void test() {
final Build current = Build.CURRENT;
}
}

Mockito/PowerMockito: Weird Stubbing Exception

I'm getting this org.mockito.exceptions.misusing.UnfinishedStubbingException but based on all posts and descriptions I could find at internet, it doesn't seem to make sense.
The exception method states a thenReturn may be missing, but it's not. I left on purpose both ways on my example code below: doReturn and thenReturn. None of them worked. Both with the very same exception message.
Also, there are no inline mocks. I prepared all static classes and am using PowerMockitoRunner.
I can't find any way out. Any one can help me find out what's going on?
Edit: I forgot to mention I'm using Mockito 1.8.5 and PowerMockito 1.4.10.
Full exception:
org.mockito.exceptions.misusing.UnfinishedStubbingException:
Unfinished stubbing detected here:
-> at org.powermock.api.mockito.internal.PowerMockitoCore.doAnswer(PowerMockitoCore.java:31)
E.g. thenReturn() may be missing.
Examples of correct stubbing:
when(mock.isOk()).thenReturn(true);
when(mock.isOk()).thenThrow(exception);
doThrow(exception).when(mock).someVoidMethod();
Hints:
1. missing thenReturn()
2. although stubbed methods may return mocks, you cannot inline mock creation (mock()) call inside a thenReturn method (see issue 53)

This doesn't mean anything to Mockito or PowerMock; you need to specify the specific call you want to mock. That makes this stubbing unfinished. See the PowerMockito when docs as an example.
However, Mockito can't tell on this line that your stubbing is unfinished—it can only raise an error when you interact with it, so it only detects the error condition later, in your mockCaptcha method.
To fix this, either finish your UrlUtil stub as follows (I specify PowerMockito to distinguish from Mockito.doNothing, though it looks like you have your static imports correct):
PowerMockito.doNothing().when(UrlUtil.class);
UrlUtil.methodYouWantToMock();
Or, to make UrlUtil suppress all its behavior by default, remove that doNothing line and put a default answer into your mockStatic call:
mockStatic(UrlUtil.class, RETURNS_SMART_NULLS);

PowerMock Static method stubbing doesn't appear to work

I've done a bunch of googling and messing around with my code but in the end I can't seem to figure out why the static mocking isn't working with PowerMock and Mockito.
I am trying to mock the LogCommand class' on() method in the JavaHg Library https://bitbucket.org/aragost/javahg which takes a javahg BaseRepository object as an argument and returns an instance of the LogCommand class. I want to have this return a mock log object so I can verify whether it's execute() command is called, but Mockito exceptions keep getting thrown.
Here's my code:
#RunWith(PowerMockRunner.class)
#PrepareForTest(LogCommand.class)
public class MyRepositoryTest {
private BaseRepository mockHgRepo;
private MyRepository myRepository;
#Before
public void before() {
mockHgRepo = mock(BaseRepository.class);
PowerMockito.mockStatic(LogCommand.class);
}
#Test
public void staticMockTest() throws IOException {
LogCommand mockLogCommand = mock(LogCommand.class);
when(LogCommand.on(any(BaseRepository.class))).thenReturn(mockLogCommand); // Problem Line!
myRepository = new MyRepository(mockHgRepo);
}
}
With this code I get stack trace:
org.mockito.exceptions.misusing.InvalidUseOfMatchersException:
Misplaced argument matcher detected here:
-> at com.mycompany.repository.config.MyRepositoryTest.getNextTagNumberTest(MyRepositoryTest.java:39)
You cannot use argument matchers outside of verification or stubbing.
Examples of correct usage of argument matchers:
when(mock.get(anyInt())).thenReturn(null);
doThrow(new RuntimeException()).when(mock).someVoidMethod(anyObject());
verify(mock).someMethod(contains("foo"))
Also, this error might show up because you use argument matchers with methods that cannot be mocked.
Following methods *cannot* be stubbed/verified: final/private/equals()/hashCode().

If I remove the matchers and use a BaseRepository object in the when instead of a matcher, it still throws an exception:
org.mockito.exceptions.misusing.MissingMethodInvocationException:
when() requires an argument which has to be 'a method call on a mock'.
For example:
when(mock.getArticles()).thenReturn(articles);
Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.
2. inside when() you don't call method on mock but on some other object.
3. the parent of the mocked class is not public.
It is a limitation of the mock engine.

Any help would be greatly appreciated--thanks!
Edit: As per #Ducan's request, here is some example code that is doing a very similar thing as the third party code I am using. Thanks!
public class TestRepository {
private String repoLocation;
public static TestRepository on (String repoLocation) {
return new TestRepository(repoLocation);
}
public TestRepository(String repoLocation, String extraflags) {
this.repoLocation = repoLocation;
}
private TestRepository (String repoLocation) {
this(repoLocation, "default flags");
}
}
#RunWith(PowerMockRunner.class)
#PrepareForTest(TestRepository.class)
public class MyRepositoryTest {
#Test
public void staticMockTest() throws IOException {
PowerMockito.mockStatic(TestRepository.class);
TestRepository mockRepository = mock(TestRepository.class);
when(TestRepository.on(anyString())).thenReturn(mockRepository);
}
}
This does not work, but gives a different exception from above, which I'm guessing may be a root problem that are somehow hidden from the ones above:

Progress? If I set it so on() calls a constructor that doesn't call another constructor this(), it doesn't give me this error.

Recently I had a similar issue trying to test my source code where static method from external class is used.
I solved this using EasyMock and PowerMock.
#RunWith(PowerMockRunner.class)
#PowerMockIgnore("javax.management.*")
#PrepareForTest({ManagementFactory.class, InstallerAppCheckerManagerImpl.class})
public class AppCheckerTester {
#Test
public void testBeanManager() throws Exception {
// this action is required by PowerMock
PowerMock.mockStatic(ManagementFactory.class);
// here is where a mock for static method is defined
MBeanServer server = PowerMock.createMock(MBeanServer.class);
EasyMock.expect(ManagementFactory.getPlatformMBeanServer()).andReturn(server);
// ...
PowerMock.replayAll();
/* some test logic between replay and verify. */
PowerMock.verifyAll();
}
}
#PowerMockIgnore defers the loading of a certain package to the parent classloader. Static method from javax.management is used in this case:
ManagementFactory.getPlatformMBeanServer()
#PrepareForTest is used to configure both your class and external class.
Hope this ideas help you in your test case.

I believe the error is in the line:
LogCommand mockLogCommand = mock(LogCommand.class);
which appears to calling the mock(Class) method from the Mockito class (due to a static import), when it should be from PowerMockito.

Your PowerMock setup seems to be incomplete.
Include the following three dependencies:
testCompile 'org.powermock:powermock-api-mockito:1.6.2'
testCompile 'org.powermock:powermock-module-junit4-rule:1.6.2'
testCompile 'org.powermock:powermock-classloading-xstream:1.6.2'
Add the following rule as a field to your unit test class:
#Rule public PowerMockRule rule = new PowerMockRule();
Additionally add the following annotation to your test class:
#PowerMockIgnore("org.mockito.*")
Then just follow the instructions on Mocking Static Methods.

MockitoAnnotations.initMocks(this);
do this on your setupMethod to enable anotations
#Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}

Casting Error related to XmlBeanFactory

When trying to run the Junit Test I got this error. This line :
AppConfig.getGatewayConfigurations().getURL();
is working fine on some places. Also I have no problem related to the path of XML File. And the class GatewayConfigurations is built well and its attributes assigned well in bean configuration file !
Here is the trace

PaymentQueryStringBuilderThirdPartyTest Class

AppConfig Class
public class AppConfig {
/**
* Default xml configurations file
*/
private final static String APP_CONFIG_FILE = "vpc-configurations.xml";
/**
* Load gateway configurations
* #return GatwayConfigurations object
*/
public static GatewayConfigurations getGatewayConfigurations(){
return (GatewayConfigurations)getBeans();
}
/**
* Get the desired configuration bean
* #param beanName
* #return BeanFactory object
*/
private static BeanFactory getBeans()
{
return new XmlBeanFactory(new FileSystemResource(APP_CONFIG_FILE));
}
}

Looking at the API for XmlBeanFactory, I can't see how it could be cast to com.me.vpc.configurations.GatewayConfigurations (not surprisingly because you have created that class / interface).
getBeans() returns a XmlBeanFactory, and getGatewayConfigurations() casts that to GatewayConfigurations. This will never work.

Spring ROO: JUnit test fails

I am having trouble executing my Spring IntegrationTests, when i run the code below it is failing at the persist method:
#RooIntegrationTest(entity = Person.class)
public class PersonIntegrationTest {
#Test
public void test() {
}
#Test
public void testCountPeople(){
Person personToPersist = PersonTestUtil.createTestPerson();
personToPersist.persist();
Long count = Person.countPeople();
assertNotNull(personToPersist);
assertTrue(personToPersist.countPeople() == 1);
}
}
The Stack trace is below

Anyone run into this problem?

It seems that you have not injected the EntityManager and the related application context to your test.
Please try adding the following line above the class declaration.
#ContextConfiguration(locations = { "/META-INF/spring/applicationContext.xml","/META-INF/spring/applicationContext-security.xml" })
and try making your test class to inhert from AbstractJUnit4SpringContextTests. Do keep in mind that you might have to implement authentication for some operations to be executed.
Your test class could look like below.
package com.myapp.test;
#ContextConfiguration(locations = { "/META-INF/spring/applicationContext.xml","/META-INF/spring/applicationContext-security.xml" })
public class TestMyService extends AbstractJUnit4SpringContextTests {
#Autowired
MyService service = new MyService();
private void setUp() {
//Do the setting up of your classes for the test
}
#Test
public void testOperation() throws IOException {
//My Test Code here
}
}
Note that you should generally have a different context for your testing purposes.
Cheers.

If you're using Springsource Tool Suite (or another Eclipse) try to clean the project. I think Eclipse someimes doesn't use the AJDT Compiler, specially at startup.
I don't remember this message from the Roo console, that uses maven under the hood.
Try "perform eclipse" from the Roo shell or even maven directly from the console (mvn clean install or something like that)

It seems that you forgot to inject the EntityManager and the application context.
Try something like this, it worked for me with Spring Roo:
import static org.junit.Assert.assertEquals;
import org.junit.Test;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import com.jitter.finance.analyzer.domain.Address;
#ContextConfiguration(locations = { "classpath*:/META-INF/spring/applicationContext*.xml"})
public class EmTest extends AbstractJUnit4SpringContextTests {
#Test
public void checkEm(){
Address a = new Address();
a.setName("Primo");
a.persist();
Address b = new Address();
b.setName("Secondo");
b.persist();
for(Address ad : Address.findAllAddresses()){
System.out.println(ad.getName());
assertEquals(ad.getName().charAt(ad.getName().length()-1), 'o');
}
}
}
