        assertThat(graph, notNullValue());
    });
}

Example 2 with EntityGraph

use of jakarta.persistence.EntityGraph in project hibernate-orm by hibernate.

@Test
@TestForIssue(jiraKey = "HHH-10633")
void testSubgraphsAreLoadedFromOrmXml(SessionFactoryScope scope) {
    scope.inTransaction(session -> {
        EntityManager entityManager = session.unwrap(EntityManager.class);
        List<EntityGraph<? super Book>> lneg = entityManager.getEntityGraphs(Book.class);
        assertThat(lneg, notNullValue());
        assertThat(lneg, hasSize(2));
        for (EntityGraph<? super Book> neg : lneg) {
            if (neg.getName().equalsIgnoreCase("full")) {
                assertThat(neg.getAttributeNodes(), notNullValue());
                for (AttributeNode<?> n : neg.getAttributeNodes()) {
                    if (n.getAttributeName().equalsIgnoreCase("authors")) {
                        assertThat(n.getSubgraphs().entrySet(), hasSize(1));
                        List<AttributeNode<?>> attributeNodes = n.getSubgraphs().get(Author.class).getAttributeNodes();
                        assertThat(attributeNodes, notNullValue());
                        assertThat(attributeNodes, hasSize(3));
                    }
