I am starting with unit tests. I've made a change to a class in which I not inject the SessionContext so I can make a lookup when needed.
#Resource
private SessionContext ctx;
Now, in my test, I would like to inject it so I can mock the lookup method:
#Mock
private SessionContext ctx;
But when I run the test, I get:

I find it strange, because I have all the dependencies required (this code works in the real application).
How do I mock and inject the SessionContext using mockito? (I can't change the mocking framework).
I went through this same problem and solved by adding a dependency only on test scope!
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-ejb_2.1_spec</artifactId>
<version>1.1</version>
<scope>test</scope>
</dependency>
If you are using below jboss ee 7 spec then you might face this problem. It was previously included in jboss ee 6 spec but some how removed from ee 7 (I am yet to find it out)
<groupId>org.jboss.spec</groupId>
<artifactId>jboss-javaee-all-7.0</artifactId>
to resolve this issue add below dependency.
<dependency>
<groupId>org.jboss.spec.javax.xml.rpc</groupId>
<artifactId>jboss-jaxrpc-api_1.1_spec</artifactId>
<version>1.0.1.Final</version>
<scope>provided</scope>

I have a maven multimodule project of the form
main
query

storage
storage-config
storage-utils
storage-common
tools
I have a class com.vnera.storage.config.ElasticsearchEmbedded.java residing under test folder in storage-config which I want to use in storage-utils from a class TestStorageUtils under test scope. storage-utils also needs storage-config in main phase.
In query module I have added dependency of storage-utils test-jar. But whenever I am trying to access TestStorageUtils in from a test in query module. It is throwing me the below error. All compilation is running fine.

The necessary pom is placed below:-

Can someone let me know what is going wrong and how can I solve this?

I have a problem with some specific classes and their transformation when used in unit tests with PowerMock.
I have looked at many SO responses already, and tried many combinations of PowerMock, JUnit, JavaAssist (overriding dependencies) but can't find a combination that works for this class.
(Some combinations of PowerMock, Junit and Javaassist didn't have this issue but the invalid stack frame one.....so stuck there also - but I would have to tackle that in a separate SO question).
If I include the class ToplevelPanel in the #PrepareForTest() list then it fails. Other JavaFX classes (like Pane.class) cause no problem.
ToplevelPanel has nothing particularly strange about it:
public class ToplevelPane extends Region implements BlockContainer, Bundleable {
Bundleable has no #Serializable annotations or anything special.
This fails when I am testing ToplevelPanel and want it in #PrepareForTest to be able to catch new()'s via whenNew() and when I am testing other classes and want to mock it.
If anyone can share a pom.xml or version combination that allows me to #PrepareForTest such a class, including capturing whenNew() it would be much appreciated.
At the bottom of this post you can find the stack trace of the failure.

Unfortunately, this issue cannot be resolved now in case if you really need to prepare for test the ToplevelPane class. But I'm not sure that it's needed.
I noticed that the ToplevelPane class doesn't have static or final method. And if remove ToplevelPane from annotation then the test fail with another error.

If update Javassist to latest version, then CgLib creates strange proxy class for modified with Javassist code, so JVM throws java.lang.VerifyError. Mockito 1 and PowerMock uses cglib 2 which isn't supported anymore.
Mockito has been migrated to ByteButty since version 2, but it only beta. PowerMock also will be move to ByteButty, but I doubt that it will be early than the end of June.
I'll try to tackle this issue in next PowerMock release (1.6.5), but I'm not sure is it feasible.
I created an issue in our bug tracker. By the way, I can reproduce the issue in case if the javafx.scene.layout.Region is mocked.
I have a java application that uses the Arquillian library for testing. I am attempting to now add the Arquillian reporter extension. As shown in the documentation at https://github.com/arquillian/arquillian-recorder/wiki/Reporter, I have added the dependency to my pom.
<dependency>
<groupId>org.arquillian.extension</groupId>
<artifactId>arquillian-recorder-reporter-impl</artifactId>
<version>1.0.0.Final</version>
</dependency>
However, now when I build my project, which worked before adding this new dependency, I get the error shown below.

This is caused by a conflict between different versions of Arquillian. This error is resolved by updating from 1.1.5.Final to:
<dependency>
<groupId>org.jboss.arquillian</groupId>
<artifactId>arquillian-bom</artifactId>
<version>1.1.8.Final</version>
<scope>import</scope>
<type>pom</type>
</dependency>
The Arquillian version needs to be updated to support the recorder.
I am following this tutorial to create tests using Selenium. I have added the com.google.guava dependency to my pom like this:
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>r09</version>
</dependency>
However, maven seems to be downloading this jar incompletely. There seem to be classes missing. One such is the com.google.common.base.Optional. On the maven repo page, towards the bottom under Source Control there is a link that shows code with the Optional class. But when I look under Maven Dependencies in eclipse, I see this:
(there is no class named Optional)
Where are the rest of the classes?
I have tried re-downloading the jar multiple times but it has had no effect.
Some more information:
I am adding the selenium server dependency like this:
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-server</artifactId>
<version>2.41.0</version>
</dependency>

You are using an old version of google-guava package, cause google guava is in the meantime at version 17. And the problem you are facing that you are looking against the current most-up-to-date code in version control.
Optional was added in Guava 10.0. Also note that the most recent version of Guava is 17.0 and that 9.0 (r09) is over 3 years old at this point.
(Also, it appears that selenium 2.41.0 depends on Guava 15.0: see the <dependencyManagement> section of the pom here.)
Here is my case. I have a AbstractController class. It has a sub class Controller. In one of AbstractController's methods a new ApplicationLock is instantiated. I'd like to mock ApplicationLock when writing ut for Controller. I wrote a test case like below.
#test
public void testMethod(){
ApplicationLock mockLock=PowerMockito.mock(ApplicationLock.class);
PowerMockito.when(mockLock.tryObtain()).thenReturn(true);
PowerMockito.whenNew(ApplicationLock.class).withArguments(argThat(new IsFile()),anyString()).thenReturn(mockLock);
}
I've added necessary annotations to the test class.
#RunWith(PowerMockRunner.class)
#PrepareForTest({AbstractController.class})
But I got the following error when running this test case. That is a static initializer in AbstractController.
Caused by: java.lang.NullPointerException
at com.acompany.controller.common.AbstractController.(AbstractController.java:65)
private static final String DEFAULT_FOLDER = AbstractController.class.getProtectionDomain().getCodeSource()
.getLocation().getPath();

You could use then:
#SuppressStaticInitializationFor({AbstractController.class})
And then, in your test case, set manually all static fields that need to be initialized, including the DEFAULT_FOLDER:
Whitebox.setInternalState(Controller.class, "DEFAULT_FOLDER", "abcd");
Whitebox.setInternalState(Controller.class, "OTHER_FIELD", new Object());
The method Class<?>.getProtectionDomain() depends too much on class loader used, so you probably won't get it to work in JUnit/PowerMock, which use their own.
