ejb + jpa + test = true?

Just finished off my test boilerplate for my javaEE project. I used the openEJB embedded container to deploy my ejb. I also fixed to possibility to test entities via hibernate in the same testcase. I think that's pretty cool since you actually can do more integration close testing even before deploying to a real application server. Trying to adapt to Antionio Goncalves nomock movement.

So I just wanted to show off my simple boilerplate as well:

@LocalClient
public class EjbTestCase {

    public static EJBContainer container;
    public static Context context;
    private static Properties prop;

    @Resource
    protected UserTransaction userTransaction;

    @PersistenceContext
    protected EntityManager entityManager;

    @BeforeClass
    public static void setup() {
        prop = new Properties();
        prop.put("jdbc/testDB", "new://Resource?type=DataSource");
        prop.put("jdbc/testDB.JdbcDriver", "org.hsqldb.jdbcDriver");
        prop.put("jdbc/testDB.JdbcUrl", "jdbc:hsqldb:mem:example");
        prop.put(Context.INITIAL_CONTEXT_FACTORY,
                "org.apache.openejb.client.LocalInitialContextFactory");

        container = EJBContainer.createEJBContainer(prop);
        context = container.getContext();
    }

    @Before
    public void setupEm() throws NamingException, SystemException,
            NotSupportedException {
        context.bind("inject",this);
        userTransaction.begin();
    }

    @After
    public void tearDownEm() throws HeuristicRollbackException, 
            RollbackException, HeuristicMixedException, SystemException {
        userTransaction.rollback();
    }

    @AfterClass
    public static void tearDown() {
        container.close();
    }
}

Pretty neat huh? At least I like it and thats whats matters right now :). As you can see you are able to get the context from the container + a entityManager in the same test.

External processes via groovy script

Had one problem one trying to kick off an external process from a groovy script. Actually two problems:

1. Not getting desired output from process (java process with INFO logging)

Solution:

process.consumeProcessOutput(System.out, System.err)

Add that method to your process that you want to kick off and it will print the stuff you want.

2. Could not build up my argument list correctly

Well I had laborated with a linux command like """ping -c 2 localhost""" and it worked like a charm to just add """my command""".execute(). However when I started to get the arguments passed from another script they got separated.

My solution was like this:

Build up the strings again and then use ProcessBuilder. Like this:

def process = new ProcessBuilder(command).redirectErrorStream(true).start();

Where the command is a ArrayList with combined parameters. Like:

def command = []

command[0] = "ping"

command[1] = "-c"

command[2] = "2"

command[3] = "localhost"

Could probably be used nice but for this time it worked nice.
