Run
How to run the sample
The source code for this sample can be found in the javaee7-samples GitHub repository. The first thing we need to do is to get the source by downloading the repository and then go into the samples folder:
git clone git://github.com/javaee-samples/javaee7-samples.git
cd javaee7-samples/jpa/datasourcedefinition-applicationxml-pu/
Now we are ready to start testing. You can run all the tests in this sample by executing:
mvn test
Or you can run individual tests by executing one of the following:
mvn test -Dtest=DataSourceDefinitionApplicationXMLPuWebTestmvn test -Dtest=DataSourceDefinitionApplicationXMLPuEJBTest

DataSourceDefinitionApplicationXMLPuWebTest

This tests that a data source defined via the data-source element in an EAR’s application.xml can be used by JPA. <p> In this test the persistence unit is defined inside a web module (.war)

<p> The actual JPA code being run is not specifically relevant; any kind of JPA operation that uses the data source is okay here.

Missing a description for the deployment. Add some javadoc to the @Deployment method. Show me how! 
@Deployment
public static Archive<?> deploy() {
    return
        // EAR archive
        create(EnterpriseArchive.class, "test.ear")

            // Data-source is defined here
            .setApplicationXML("application-web.xml")

            // JDBC driver for data source
            .addAsLibraries(Maven.resolver()
                .loadPomFromFile("pom.xml")
                .resolve("com.h2database:h2")
                .withoutTransitivity()
                .asSingleFile())

            // WAR module
            .addAsModule(
                create(WebArchive.class, "test.war")

                    // Persistence unit is defined here, references data source
                    .addAsResource("META-INF/persistence.xml")

                    // Service class that uses persistence unit
                    .addPackages(true, DataSourceDefinitionApplicationXMLPuWebTest.class.getPackage())
        );
}
Missing a description for the test scenario. Add some javadoc to the @Test method. Show me how! 
@Test
public void insertAndQueryEntity() throws Exception {

    testService.saveNewEntity();

    List<TestEntity> testEntities = testService.getAllEntities();

    assertTrue(testEntities.size() == 1);
    assertTrue(testEntities.get(0).getValue().equals("mytest"));
}

DataSourceDefinitionApplicationXMLPuEJBTest

This tests that a data source defined via the data-source element in an EAR’s application.xml can be used by JPA. <p> In this test the persistence unit is defined inside an EJB module (.jar)

<p> The actual JPA code being run is not specifically relevant; any kind of JPA operation that uses the data source is okay here.
