Missing Assertion Message
^^^^^
**Definition:**

* A test fails. Upon examining the output of the Test Runner, we cannot determine exactly which assertion had failed.


**Code Example:**

.. code-block:: java
    
    public void testInvoice_addLineItem7() {
        LineItem expItem = new LineItem(inv, product, QUANTITY);
        //  Exercise
        inv.addItemQuantity(product, QUANTITY);
        // Verify
        List lineItems = inv.getLineItems();
        LineItem actual = (LineItem)lineItems.get(0);
        assertEquals(expItem.getInv(), actual.getInv());
        assertEquals(expItem.getProd(), actual.getProd());
        assertEquals(expItem.getQuantity(), actual.getQuantity());
    }
