Example 7 with TestEntity

use of org.javaee7.jpa.dynamicnamedquery.entity.TestEntity in project javaee7-samples by javaee-samples.

the class DynamicNamedQueryTest method testDynamicNamedCriteriaQueries.

@Test

    // Nothing inserted yet, data base should not contain any entities 
    // (this tests that a simple query without parameters works as named query created by Criteria)

    // The total amount of entities should be 1
    assertTrue(testService.getAll().size() == 1);
    // The entity with "myValue" should be found
    // (this tests that a query with a parameter works as named query created by Criteria)
