     con = controller;
     PageReference thisPage = ApexPages.currentPage();
     List<String> url = thisPage.getUrl().split('\\?');
     queryString = url[1];
     System.debug('----->>'+queryString);


 } 
 public PageReference saveNew() 
 { 
 try
 {
 con.save(); 
 Schema.DescribeSObjectResult describeResult = con.getRecord().getSObjectType().getDescribe();
 PageReference pr = new PageReference('/' + describeResult.getKeyPrefix() + '/e?'+ queryString); 
 pr.setRedirect(true);
 return pr;

@isTest
Private class SaveAndNewTest {

    static testMethod void saveNewTest() {
        // here I am taken account, you have to create your standardcontroller object record
        Account ac = new Account (Name='sample ac');
        Insert ac;
        
        ApexPages.StandardController sc = new ApexPages.StandardController(ac);
        PageReference pageRef= page.MyVFPageName;  // add your page name
        System.Test.setCurrentPage(pageRef);
        pRef.getParameters().put('id', 'abc\\?def'); 
        SaveAndNew savenNew = new SaveAndNew(sc);
        savenNew.saveNew();
    }
}
86% code coverage.It will cover entire code except catch condition.

Hello Nagarjun ,
I followed your process still no coverage.

@isTest Private class SaveAndNewTest
 {    
static testMethod void saveNewTest()
 {   
      // here I am taken account, you have to create your standardcontroller object record         Expense_Line_Item__c ac = new Expense_Line_Item__c(Expense__c='EXP-00135',Amount__c=1200);     
    Insert ac;        
          ApexPages.StandardController sc = new ApexPages.StandardController(ac);         PageReference pageRef= page.expenselineitemsfields;  // add your page name       
  System.Test.setCurrentPage(pageRef);  
       pageRef.getParameters().put('id', 'abc\\?def');      
    SaveAndNew savenNew = new SaveAndNew(sc);   
      savenNew.saveNew();  
   }
}
