I am trying to write a test class for a controller extension and cannot seem to get it to work I keep getting a error: "System.QueryException: List has no rows for assignment to SObject on test class" and cannot figure out why.  My controller and test class are below.

public class HardwareWoSalesOrderLineEdit {
 public HardwareWoSalesOrderLineEdit(ApexPages.StandardController controller) {
     //parent record
  this.proj =[select Sales_Order__c, Id, X2nd_Sales_Order__c From Work_Order__c Where Id = :ApexPages.currentPage().getParameters().get('id')];    
     // child records
     this.line = [ SELECT SCMC__Quantity__c, Item_Name__c,SCMC__Quantity_Shipped__c, Category__c,     SCMC__Item_Description__c, PM_Ordering_Details__c, Quantity_to_Ship__c, Remaining_Quantity__c  
      FROM SCMC__Sales_Order_Line_Item__c
      WHERE (Item_Type__c = 'Hardware'   AND SCMC__Status__c != 'Completed' AND SCMC__Status__c != 'Shipped' AND Category__c != 'Physical Install' AND SCMC__Status__c != 'Cancelled' AND SCMC__Sales_Order__c = :proj.Sales_Order__c) OR
             (Item_Type__c = 'Hardware'   AND SCMC__Status__c != 'Completed' AND SCMC__Status__c != 'Shipped' AND Category__c != 'Physical Install' AND SCMC__Status__c != 'Cancelled' AND SCMC__Sales_Order__c = :proj.X2nd_Sales_Order__c)  ORDER BY Category__c ASC   ];     
     }
    //get sales order lines                 
  public SCMC__Sales_Order_Line_Item__c[] getline() { 
  return this.line; 
 } 
    
 // save method to save changes to the sales order lines
 public pagereference saveChanges() { 
  upsert this.line;
  pageRef.setRedirect(true); 
return pageRef;
 }
    
 // class variables
public PageReference pageRef = new PageReference(ApexPages.currentPage().getUrl()); 
public Work_Order__c proj;
public SCMC__Sales_Order_Line_Item__c[] line; 

}



TEST CLASS
