The error is because your code Account accRec query is not able to find any records. Please make sure you put that in try .. catch block. 

In your test class. 

You need to pass the Page Parameters in your code to query the Account table, for that you need set the pagereference, something like below.

@isTest
private class AddInvoiceCreditToEducation_UT{
  static testMethod void My_method(){ 
      // setup a ship to account
        Account shipTo = new Account();
        shipTo.Name = 'PSAV 6FOO';
        shipTo.Type = 'Supplier';
        shipTo.Expiration__c = system.today()+1;
        shipto.Current_Ed_Amount__c = 100;
        insert shipTo;
        Contract ocon = new Contract(name= 'test');
        ocon.AccountId=shipTo.id;
        ocon.StartDate = date.newInstance(2014, 10, 7);
        insert ocon;
        Contact ocont = new Contact(LastName= 'test');
        ocont.AccountId=shipTo.id;
        insert ocont;
        License_Invoice__c o1 = new License_Invoice__c();
        o1.Account__c = shipTo.id;
        o1.Contract__c = ocon.id;
        o1.Bill_To__c = ocont.id;        
        insert o1;
        List<Invoice_Product__c> invoicelist=new list<Invoice_Product__c>();
        Invoice_Product__c oip = new Invoice_Product__c(Contract__c = ocon.id,License_Invoice__c=o1.Id);
        Account accRec=[select id,name,Current_Ed_Amount__c,Expiration__c from Account where id=:shipTo.id];

   Test.startTest(); 
    
     PageReference testPage = Page.<your Visualforce Page Name>;
     Test.setCurrentPageReference(testPage);
     testPage.currentPage().getParameters().put('id',shipTo.Id);
     testPage.currentPage().getParameters().put('invId',o1.Id); // Assuming its the invoice record, no reference in code though 
   
     AddInvoiceCreditToEducation obj=new AddInvoiceCreditToEducation();
     obj.cancel(); // This one will also have 

   Test.stopTest();
     
   
  }
}
