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:
@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);
}
