Hello,

I am new to this and I want to test a simple class below but it is not executing my sql queries but through the visualforce page this works fine.

Please guide me what I am doing wrong.

public with sharing class FetchDocumentId
{

public String documentname{ get; set; }
public String docid{ get; set; }

public string getdocId()
{
return docid;
}
public void documentId()
{
documentname=System.currentPageReference().getParameters().get('documentname');
System.debug('doc name:'+documentname);
//documentname='Checklist_Comment_and_Feedback_Template';
try{
List<Document> lstDocument = [Select Id,Name from Document where Name =:documentname limit 1];
System.debug('!!!!!!!!!!!!!'+lstDocument);//always null
string strOrgId = UserInfo.getOrganizationId();
string strDocUrl = 'https://'+ApexPages.currentPage().getHeaders().get('Host')+ '/servlet/servlet.FileDownload?file='+lstDocument[0].Id+'&oid=' + strOrgId;
System.debug('doc url'+strDocUrl );
docid=lstDocument[0].Id;
System.debug('docid:'+docid);
}catch(Exception e){System.debug('Document not found');}
//return docid;
}

public static testmethod void testdocumentId()
    {
      FetchDocumentId d= new FetchDocumentId();

//This is the page that uses this controller
      Test.setCurrentPageReference(new PageReference('Page.OHSESMain')); 
      System.currentPageReference().getParameters().put('documentname', 'Checklist_Comment_and_Feedback_Template');
     
       Test.startTest();
       
       d.documentId();
       String docmentId=d.getdocId();
       Test.stopTest();
       
        //assert results
       System.assert(docmentId!=null,'Document is null');
        
     }

}

Thanks
