Second Guess The Calculation
^^^^^
**Definition:**

* Where rather than using concrete test data, we use something that needs us to calculate the correct answer ahead of assertion


**Code Example:**

.. code-block:: java

    @Test
    public void testCalculatePrice() {
        Order order = new Order();
        order.addProduct(new Product("Product A", 10.0, 2));
        order.addProduct(new Product("Product B", 5.0, 3));
        
        double expectedPrice = 10.0 * 2 + 5.0 * 3;
        double actualPrice = order.calculatePrice();
        
        assertEquals(expectedPrice, actualPrice, 0.001);
    }
