Junit Mockito test cases using Jupiter for Hazelcast Jet Pipiline

Question

I am trying to write the Junit test cases for the below hazelcast Jet Pipeline.

My component:

@Component
public class UserJetJob extends AbstarctJetJob {

    private static final String TABLE_NAME = "User";

    @Autowired
    private ClientConfig clientConfig;

    @Value("${jdbc.connection_url}")
    private String connectionUrl;

    @Override
    public Pipeline buildPipeline() {
        Pipeline p = Pipeline.create();
        p.readFrom(Sources.jdbc(connectionUrl,
                "SELECT * FROM " + TABLE_NAME,
                UserJetJob::buildUser))
            .map(a -> Util.entry(a.getId(), a))
            .writeTo(Sinks.remoteMap("userMap", clientConfig));
        return p;
    }

}

I am writing a JUnit test case for the method public Pipeline buildPipeline() but it's failing due to the resultset.

@ExtendWith(MockitoExtension.class)
public class UserJetJobTest extends JetTestSupport {

    @InjectMocks
    UserJetJob userJetJob;

    @Mock
    private JetInstance jet;

    @Mock
    private ClientConfig clientConfig;

    @Test
    public void buildPipelineUser() {
        Pipeline p = Mockito.mock(Pipeline.class);
        // Mockito.when(p.readFrom(Sources.jdbc(Mockito.anyString(), Mockito.anyString(), Mockito.eq(ResultSet.class))).then
        userJetJob.buildPipeline();
    }
}

Could you please help me with how to write JUnit test cases?
