Artifact: Defect

•A Defect is a system anomaly (like a sw fault)

Artifact: Evaluate Test

Test the system as a whole

•Installation test

•Configuration test

•Negative test

•Stress tests

1.1. Test Case 1

Verification of the generation of the billing events through the Customer Care interface

In order to perform this test, the web Customer Care GUI has to be used.

An account has to be created in the system. This test case can be performed even if the account has not subscribed to a product.

Test Step

Input/Action Expected Output Result

1 Create an account or look up an existing one.Use the apposite link to create a billing event.  

A billing event is created.The account balance change reflects the presence of the new billing event

Account balance: an amount is not shown in a proper way. Se screen shot Test Case 1.

The Unified Software Development The Unified Software Development Process: Test ProcedureProcess: Test Procedure

In principle there are two ways to test

1. Incremental test

• Top-down or Bottom-up

2. Total test

The Unified Software Development The Unified Software Development Process: My experiences Process: My experiences

•Boundary tests

•Input field my can only accept positive integers

•Test

•Input = 0, 1, -1, -1000, -0, Max value, 1.2, 0.1, -0.1

•Make sure you know what the result of the test is meant to be.

•Plan test in advance

•Document your test

•Involve the end users in the system test

•Be careful to align the users expectations
