Can PowerMock be used with ElasticsearchIntegrationTest? - java

I have been using ElasticsearchIntegrationTest for testing my code without elasticsearch server. There are few private members in my class so thought of using Powermock for accessing private members. While running test i get exception.
Can Powermock be used with ElasticsearchIntegrationTest??
Code :
import org.elasticsearch.test.ElasticsearchIntegrationTest;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
#RunWith(PowerMockRunner.class)
#PrepareForTest(AbstractTest.class)
public class PowerMockitTest extends ElasticsearchIntegrationTest{
AbstractTest abstractTest = mock(AbstractTest.class);
#Test
public void testPowerMokito() throws Exception{
doReturn(internalCluster().transportClient()).when(abstractImporter, "initClient");
}
}
Exception :
java.lang.IllegalStateException: Failed to transform class with name org.elasticsearch.test.ElasticsearchIntegrationTest. Reason: cannot find org.apache.http.impl.client.CloseableHttpClient at

Base on your stack trace I can guess that either org.elasticsearch.test.ElasticsearchIntegrationTest or one of superclass or field depends on org.apache.http.impl.client.CloseableHttpClient and the class cannot be found in Runtime, so it means class not in test class path.

Jmockit code coverage and static initialization

We are developing unit test for a Java App that depends on an external jar. We use JMockit, and the unit test can run successfully. Then we enable JMockit code coverage. Then the Jmockit code coverage code somehow calls into the static initialization code of a class in the external jar. Since that class is not supposed to run in a test env, this causes an exception. Note that
1. The unit test can run successfully if code coverage is not enabled
2. The stack trace shows nothing of the class we are testing, it comes from the JMockit code (mockit.coverage.CodeCoverage.transform) to the static initialization of the third party class.
3. This is an external class in a jar, jmockit is not supposed to do code coverage about it according to the document, right? Does mockit.coverage.modification.ClassModification.modifyClassForCoverage mean instrumenting the code?
4. We tried -Djmockit-codecoverage-excludes flag, and it did not help.
Is this a bug of JMockit code coverage?

PowerMock & JavaAssist "Failed to transform class"

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 run my test with gradle task cleanTest test
I tried to invalidate and restart IntelliJ cache by it didn't help.
How could I get rid of this exception ?
The solution was quite easy.
gradle clean
Some way, gradle was keeping a wrong reference to the old class emplacement.

This is my cucumberRunner file
import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;
#RunWith(Cucumber.class)
#Cucumber.Options(
format={"pretty","json:target"},
features={"src/features"}
)
public class CucumberRunner {
}
Try this:
import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;
#RunWith(Cucumber.class)
#CucumberOptions(
format={"pretty","json:target"},
features={"src/features"}
)
public class CucumberRunner {
}
the "." in CucumberOptions is wrong
