BeforeSuite|Test|Class

[threecuptea]

My project is written in EJB3.  In  order to test EJB, I have a parentClass
public abstract class EJBIntegrationTest with two BeforeSuites method
@BeforeSuite(alwaysRun = true)
    @Parameters({"deploy_beans_xml", "scan_classpath","jndi_name_emf", "jndi_name_usertx"})
    public void startContainer(String deployBeansXml, String scanClasspath,
                               String jndiNameEMF, String jndiNameUserTx)
            throws Exception {
     
        EJB3StandaloneBootstrap.boot(null);
        EJB3StandaloneBootstrap.deployXmlResource(deployBeansXml);
        EJB3StandaloneBootstrap.scanClasspath(scanClasspath.replace("/", File.separator));
    }
//Initialize environment for all subclass.
@BeforeSuite(alwaysRun = true, dependsOnMethods="startContainer")
    public void initialEnvironment() throws Exception {      
        jndi = new InitialContext();
        programSession = lookupLocalBean(RemoteProgramSession.class, "ProgramSessionEJB");
        metaSession = lookupLocalBean(LocalMetadataSession.class,  "MetadataSessionEJB");
        authoringSession = lookupLocalBean(LocalAuthoringSession.class, "AuthoringSessionEJB");
        dashboardSession = lookupLocalBean(LocalDashboardSession.class, "DashboardSessionEJB");    
       EntityManager em = getEntityManagerFactory().createEntityManager();
        session  = (Session) em.getDelegate();
    }

All EJB test classes extends EJBIntegrationTest with a BeforeClass method to prepare default testing variables like the followings:
@Test(groups = "persistence-pandads-prgmgrp")
public class ProgramSessionTest extends EJBIntegrationTest {

@BeforeClass(groups="persistence-pandads-prgmgrp")
    public void prepareSettings() {
        dfltNetwork = programSession.getNetworkById(1);
        dfltContentRating = programSession.getContentRatingById(5);
        dfltProductType = programSession.getProductTypeById(2);
:
:}

It works fine until I add a second EJB test class MetadataSessionTest.   I found out prepareSettings method would always throws NullPointerException for whichever test class run second (test run in random order) because it is not able to access those EJBSession beans initialized in BeforeSuite method initialEnvironment.  prepareSettings method works fine for
whichever test class run first.  

I tried many ways.  Finally, I get it work by changing initialEnvironment. to BeforeTest method.  (Test includes all test classes).  initialEnvironment seems to run once for each test class (It's not my original intent)

I like to know
1) Why is the second test class unable to access variables initialized in before test suite method? I like to know the difference of implementation of BeforeSuite, BeforeTest, BeforeClass and how would that affect the running sequence and accessibility.
2) What should we put in beforeSuite, beforeTest, beforeClass in principle? What's your suggestion regarding to my case?

A few thoughts.

• Are you sure you want @BeforeTest and not @BeforeMethod?  The latter is much more common in my experience.
  
  
• Can you simplify your code with just a few logs for each method called and post the log here?  This way we will see what methods are being invoked and in what order (you can also set verbose="10" in testng.xml and you'll get this information as well.

I'm sorry I don't understand what you are saying.

How about you

• Post your code
• Tell me what ordering of invocation you are seeing
• Tell me what ordering you expected

?

EJBIntegrationTest.java
ProgramSessionTest.java
MetadataSessionTest.java
Here you go.
Expected all passed but got NullPointerException in prepareSetting of either ProgramSessionTest or MetadataSessionTest class depending upon which class run second.  See BeforeSuite.log in my previous email.

It works fine once I switch to use @BeforeTest annotation on initialEnvironment.  See BeforeTest.log in my previous email.

So it looks like initialEnvironment() is never called with @BeforeSuite but does get called if you use @BeforeTest instead?

Please set <suite verbose="10"> and post the log.

Here you go.
Expected all passed but got NullPointerException in prepareSetting of either
ProgramSessionTest or MetadataSessionTest class depending upon which class
run second.  See BeforeSuite.log in my previous email.

It works fine once I switch to use @BeforeTest annotation on
initialEnvironment.  See BeforeTest.log in my previous email.

I attached BeforeSuite.log & BeforeTest.log  with my message posted at 11:21 AM.  Let me know if you can access them.
Judging from BeforeSuite.log,
It did call once in initialEnvironment() with @BeforeSuite.

The issue is that only the first running test class can access those sessionBean and EntityManageFactory retrieved in initialEnvironment() with @BeforeSuite.
All the following running test classes is unable to access them. That's why it throws NullPointerException.

I won't get the same trouble if I annotate initialEnvironment() with @BeforeTest.  I just like to know why.
Thanks.

The only explanation I can think of (which, again, does not seem to be TestNG related) is that you are setting these variables to null some time after the first test has run.  This would explain why your test fails with @BeforeSuite but not if you use @BeforeTest (and again, I think you really want to use @BeforeMethod and not @BeforeTest).
