Workflow Process Implementation not found

Question

Hello,
     I've created a workflow process in AEM 5.6.  When I initiate the workflow, the workflow is not completed and in the Inbox Console, I see 'process implementation is not found'.
Here is the sample workflow process:
package com.test.workflowtest;
import org.apache.felix.scr.annotations.Component;
import org.apache.felix.scr.annotations.Properties;
import org.apache.felix.scr.annotations.Property;
import org.apache.felix.scr.annotations.Service;
import org.osgi.framework.Constants;
import org.apache.felix.scr.annotations.Reference;
import com.day.cq.workflow.WorkflowException;
import com.day.cq.workflow.WorkflowSession;
import com.day.cq.workflow.exec.WorkItem;
import com.day.cq.workflow.exec.WorkflowData;
import com.day.cq.workflow.exec.WorkflowProcess;
import com.day.cq.workflow.metadata.MetaDataMap;
import com.adobe.granite.workflow.WorkflowException;
import com.adobe.granite.workflow.WorkflowSession;
import com.adobe.granite.workflow.exec.WorkflowProcess;
import com.adobe.granite.workflow.exec.WorkItem;
import com.adobe.granite.workflow.metadata.MetaDataMap;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.apache.sling.api.resource.ResourceResolverFactory;
import org.apache.sling.api.resource.ResourceResolver;
@Component
@Service
@Properties({
        @Property(name = Constants.SERVICE_DESCRIPTION, value = "Test Process."),
        @Property(name = Constants.SERVICE_VENDOR, value = "TEST"),
        @Property(name = "process.label", value = "Test WF Process")})
public class Test implements WorkflowProcess{
   private static final Logger log = LoggerFactory.getLogger(Test.class);
          @Reference
          private ResourceResolverFactory resourceResolverFactory;
          public void execute(WorkItem item, WorkflowSession session, MetaDataMap args)
        throws WorkflowException {
        log.debug("======== Test Process ===========");
        ResourceResolver resolver = null;
        try{
                              resolver = resourceResolverFactory.getAdministrativeResourceResolver(null);
        }catch(Exception e)
            e.printStackTrace();

=======
Findings:  Gettting exception only when I use below code in the workflow process.
@Reference
  private ResourceResolverFactory resourceResolverFactory;
Any help would be more helpful..
Thanks
