PowerMockRunner + maven surefire (no tests found) && ArrayIndexOutOfBoundsException

[davis]

Hi, when I use PowerMockRunner with maven surefire, it cannot find my
test:

-------------------------------------------------------
T E S T S
-------------------------------------------------------
There are no tests to run.

Results :

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

...but when I run the same test in Eclipse it runs and passes as
expected. I set the test up like this:

@RunWith( PowerMockRunner.class )
@PrepareForTest( {SomeClass.class} )
@SuppressStaticInitializationFor({"com.example.SomeClass",
"com.example.SomeOtherClass"})
public class MyTest {

@Test
public void testSomething( ) { ... }

Now, when I run the test via surefire and tell it which test to run it
executes the test but blows up a different way:

initializationError0(com.example.MyTest) Time elapsed: 0.016 sec <<<
ERROR!
java.lang.IllegalStateException: Failed to transform class with name
com.example.MyTest. Reason: 3

I am pulling PowerMock into maven as per the Twiki =>
http://code.google.com/p/powermock/wiki/EasyMock_maven with JUnit 4.4
and I'm also using EasyMock

<dependency>
<groupId>org.powermock.modules</groupId>
<artifactId>powermock-module-junit4</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.powermock.api</groupId>
<artifactId>powermock-api-easymock</artifactId>
<version>${powermock.version}</version>
<scope>test</scope>
</dependency>

and using ${powermock.version} == 1.3.5

Can someone give me a pointer on what I can do to resolve this?

Thanks in advance,
Davis

Ok, I found the solution to the second problem -- different versions
of javassist. I ran

mvn project-info-reports:dependencies

to generate a full dependency report and look at the dependencies
powermock has vs. my other dependencies, and I found this:

org.hibernatespatial:hibernate-spatial:jar:1.0-M2-axeda-1.0
(provided)
org.hibernate:hibernate:jar:3.2.4.sp1 (provided)
com.vividsolutions:jts:jar:1.10 (provided)
jboss:javassist:jar:3.6.ga (provided)

which PowerMock also needs -- except a newer version:

org.powermock:powermock-core:jar:1.3.5 (test)
org.powermock.reflect:powermock-reflect:jar:1.3.5 (test)
javassist:javassist:jar:3.10.0.GA (test)

I excluded the jboss:javassist and the ArrayIndexOutOfBoundsException
goes away when I run

mvn test -Dtest=MyTest

...but I still can't just run:

mvn test

it reports There are no tests to run -- any ideas?

Ok, I fixed this too. Not sure why I have to add this, but I did in
order to configure surefire. I've never had to do this before:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<includes>
<include>**/*/*Test.java</include>
</includes>
</configuration>
</plugin>

Never seen this before, seems very strange. If you find out what's causing it please let us know.

I suspect the surefire plugin config that caused this may be pulled in
via a parent pom.xml -- that is why I'm seeing this. Local config
issue -- safe to ignore.
