### Question:
JPAEdmEntityType extends JPAEdmBaseViewImpl implements JPAEdmEntityTypeView { @Override public JPAEdmBuilder getBuilder() { if (builder == null) { builder = new JPAEdmEntityTypeBuilder(); } return builder; } JPAEdmEntityType(final JPAEdmSchemaView view); @Override JPAEdmBuilder getBuilder(); @Override EntityType getEdmEntityType(); @Override javax.persistence.metamodel.EntityType<?> getJPAEntityType(); @Override List<EntityType> getConsistentEdmEntityTypes(); @Override EntityType searchEdmEntityType(final String jpaEntityTypeName);  }### Answer:
@Test public void testGetBuilder() { assertNotNull(objJPAEdmEntityType.getBuilder()); }
@Test public void testGetBuilderIdempotent() { JPAEdmBuilder builder1 = objJPAEdmEntityType.getBuilder(); JPAEdmBuilder builder2 = objJPAEdmEntityType.getBuilder(); assertEquals(builder1.hashCode(), builder2.hashCode()); }
