POEasyMock and Hibernate Criteria Queries

Body
copied!<p>I am trying to test a dao method which uses the hibernate criteria API, using JUnit4 and EasyMock 2.4. </p> <p>When I run the test fixture 'testGetAsset' I receive the following exception:</p> <pre><code>java.lang.AssertionError: Unexpected method call add(name=Test): add(name=Test): expected: 1, actual: 0 add(source=GSFP): expected: 1, actual: 0 uniqueResult(): expected: 1, actual: 0 at org.easymock.internal.MockInvocationHandler.invoke(MockInvocationHandler.java:32) at org.easymock.internal.ObjectMethodsFilter.invoke(ObjectMethodsFilter.java:61) at $Proxy7.add(Unknown Source) at com.hsbc.sfd.funddb.persistence.dao.AssetDaoImpl.getAsset(AssetDaoImpl.java:80) at com.hsbc.sfd.funddb.persistence.AssetDaoTest.testGetAsset(AssetDaoTest.java:62) </code></pre> <p>I think the problem is related to the mock criteria object not being initialized with Asset.class, but I'm quite a beginner with EasyMock and mock objects in general, so I'd really appreciate it if someone could take a look and tell me what I need to do to make the test pass.</p> <p>Many thanks, Mark</p> <p>Code is below:</p> <h2>Dao Method</h2> <pre><code>public Asset getAsset(String name, Source source) { return (Asset) this.sessionFactory.getCurrentSession() .createCriteria(Asset.class) .add(Restrictions.eq("name", name)) .add(Restrictions.eq("source", source)) .uniqueResult(); } </code></pre> <h2>Test Class</h2> <pre><code>public class AssetDaoTest { private SessionFactory factory; private Session session; private Criteria criteria; private AssetDaoImpl dao; @Before public void setUp() { factory = createMock(SessionFactory.class); session = createMock(Session.class); criteria = createMock(Criteria.class); dao = new AssetDaoImpl(); dao.setSessionFactory(factory); } @Test public void testGetAsset() { String name = "Test"; Source source = Source.GSFP; Asset asset = new Asset(); asset.setName(name); asset.setSource(source); expect(factory.getCurrentSession()).andReturn(session); expect(session.createCriteria(Asset.class)).andReturn(criteria); expect(criteria.add(Restrictions.eq("name", name))).andReturn(criteria); expect(criteria.add(Restrictions.eq("source", source))).andReturn(criteria); expect(criteria.uniqueResult()).andReturn(asset); replay(factory, session, criteria); dao.getAsset(name, source); } } </code></pre>
