SeamTest and UnitDBSeamTest configuration issue - doesn't work out of the box

[themathmagician]

I have spent quite some time trying to figure out how to run unit/integration tests using Seam.
I have looked for this information in the Seam Documentation, and also the books Seam in Action, and Seam Evolution.

The examples in the documention do not work out of the box, if you use them on a seam-gen project.

There have been many posts here on this forum regarding running the seam integration tests...
I see that these tests are working for the example projects, but because the buildfile is SO different from the one generated by seam-gen, I haven't been able to figure out what the trick is. (Apparently, the example projects when tested don't have a persitence.xml file at all?)

Digging trough this forum, and seeing how many people had problems with running tests, I thought it might be helpful to create a "Test example" project, which has the same structure as a typical seam-gen project, and demonstrates the various options for testing.

Hope you guys can help me in finding out, which magical combination of datasource, persitence.xml settings etc does the trick!

+++ Here are my steps:


I genereated a new project using seam-gen.
I used the seam-gen new-entity and new-action to create the entity User, the view user.xhtml and the action class UserBean.
I didn't change the configuration of the project.

+++ I have made 3 test-types:

# Integration test - made by seam-gen - this one is working.
`
new FacesRequest() {
                        @Override
                        protected void invokeApplication() {
                                invokeMethod("#{user.user}");
                        }
                }.run();
        }
`
This test is passing!

# A test that uses the facelet name in the contructor of FacesRequest

`
@Test
  public void test_user_ui_with_facelet_param_in_constructor() throws Exception {
                       
                        new FacesRequest("/user.xhtml") {
                                @Override
                                protected void updateModelValues() throws Exception {
                                        // Bind simulated user input data objects
                                        // to Seam components
                                        assert getFacesContext().getViewRoot() != null;
                                }

                                @Override
                                protected void invokeApplication() {
                                        // Invoke the UI event handler method for
                                        // the HTTP POST button or link
                                }

                                @Override
                                protected void renderResponse() {
                                        // Retrieve and test the response
                                        // data objects
                                }
                        }.run();
                }
        }`

This test is failing, see the stack trace below ...

# A test that extends UnitDBSeamTest

`public class UnitDBPersistenceTest extends DBUnitSeamTest {

        protected EntityManager em;

        @BeforeTest
        public void init(){
                //EntityManagerFactory emf = Persistence.createEntityManagerFactory("run");
                //em = emf.createEntityManager();
        }
       
        @AfterTest
        public void close(){
                em.close();
        }
       
       
        @Test
        public void test_user_crud_using_unitdb(){
                User user = new User();
        }

        @Override
        protected void prepareDBUnitOperations() {
                beforeTestOperations.add(new DataSetOperation("cruddataset.xml"));
        }
}`
This test if failing, see the stacktrace below.

The cruddataset is very simple:

`<dataset>
        <USER
                id="1"
                name="hans"
                version="1"
        />
</dataset>

The User, UserBean and user.xhtml are trivial, autogenerated by seam.

Its clearly a configuration issue - can anybody help out?

Dont put any of the entity manager items in the before or after ... i used to get strange errors when i tried to do that stuff as well.

AbstractDBUnitSeamTest uses getResourceAsStream() to retrieve the dataset file, so you'll need to put this file within a source folder in the test project.

I usually do the following:

1. create a testdata package under test-src.


2. create two more packages under it: testdata.sets for datasets and testdata.binaries for binaries (even if you don't use binaries in your tests, you still need to provide an existing binaries location).


3. configure the binaryDir parameter of testng.xml to point to testdata/binaries/.


4. when adding the dataset in your beforeTestOperations method, refer to xml datasets as testdata/sets/myset.xml.

This should get you going.

Just a quick note: data source name in my testng.xml and persistence.xml are the same. May be this causes some problems?

No, I too have the datasource name identical in both testng.xml and persistence.xml and it works just fine. You don't specify your specific problem or report any exceptions, but it could be that your datasource transaction type is RESOURCE_LOCAL... it shouldn't (you're testing within the jboss container and are using JBossTransactionManagerLookup, which returns a JTA transaction).
