Irrelevant Information

Definition:

The test is exposing a lot of irrelevant details about the fixture that distract the test reader from what really affects the behavior of the SUT.

Code Example:

public void testAddItemQuantity_severalQuantity_v10(){
    //   Setup Fixture
    Address billingAddress = createAddress( "1222 1st St SW", "Calgary", "Alberta", "T2N 2V2", "Canada");
    Address shippingAddress = createAddress( "1333 1st St SW", "Calgary", "Alberta", "T2N 2V2", "Canada");
    Customer customer = createCustomer( 99, "John", "Doe", new BigDecimal("30"),
                       billingAddress, shippingAddress);
    Product product = createProduct( 88,"SomeWidget",new BigDecimal("19.99"));
    Invoice invoice = createInvoice(customer);
    // Exercise SUT
    invoice.addItemQuantity(product, 5);
    // Verify Outcome
    LineItem expected = new LineItem(invoice, product,5, new BigDecimal("30"), new BigDecimal("69.96"));
    assertContainsExactlyOneLineItem(invoice, expected);
}
