Question No : 2

You are the Test Manager on a project following an iterative life-cycle model. The project should consist of nine iterations of one month duration each. It is planned to develop the most important features to have a stable core of the application in the first three iterations and to add the additional features in the last six iterations.
At the beginning of the first iteration, only a draft version of the requirements specification document for the core features is available. Assume that during each of the first three iterations, the chosen features are fully completed and unit tested.
Which of the following statements is true in this context? K4 3 credits

A.The system test phase should start when all the requirements are frozen
B.You should allocate a large effort for system testing during the first three iterations
C.You should allocate all the effort for the system test phase only in the last iteration
D.You should apply the same test strategy as used in a sequential life cycle model

K2 1 credit

A.Test reporting activities can’t be influenced by the use of an iterative lifecycle model with short iterations
B.Test reporting activities are not important for projects adopting an iterative lifecycle model with short iterations
C.Test reporting activities are less important for projects adopting an iterative life cycle model with short iterations. They should be performed at the end of the last iteration

You are the Test Manager for a project to develop a client-server application that allows wine vendors to order custom-assorted packages of wines of several winemakers to sell special packages in their wine shops.
You decide to apply a blended risk-based and reactive testing strategy. Below the exit criteria for the system testing.
EXCR1- Each “critical” quality risk item must be covered by at least one test condition
EXCR2- Each “critical” requirement must be covered by at least one test condition
The following are the “critical” requirements of the application:
REQ-SEL-1. The application shall allow the user to order only one package at a time
REQ-SEL-2. The application shall allow the user to select between four different packages (2-bottles, 6-bottles, 12-bottles, 15-bottles)
REQ-SEL-3. The application shall allow the user to order a package containing at least 1 bottle and no more bottles than the package size. No error messages shall be displayed if the user selects a valid number of bottles (at least 1 bottle and no more than the package size)
REQ-SEL-4. The application shall display an error message “Invalid number of bottles” if an invalid number of bottles is selected by the user (zero bottles or a number higher than the package size)
REQ-PAY-1. The application shall allow the user to pay with the three accepted credit cards (Visa, MasterCard, American Express)
REQ-PAY-2. The application shall display an error message “Invalid credit card” if invalid credit card data are given by the user
QUSTION NO: 11
The following is the unique “critical” quality risk item that has been identified:

Question No : 11

You are the Test Manager for a project to develop a web customer portal of a Pay-TV company that allows customers (with a smartcard and a set-top box) to purchase digital contents.
In the "select" page the system displays a dialogue where the customer can select the items (digital contents) he/she is interested in. In this page he/she can add one or more items to a shopping cart. An item consists of a product and a duration.
There are three types of products: Movie, sport and premium (movie and sport).
There are four possible durations: 1 months, 2 months, winter (from the beginning of January to end of March) and summer (from the beginning of July to end of September).
All the combinations of products and durations are allowed to define an item. Thus there are twelve possible items. A maximum of six different items can be added to the shopping cart at a time.
When the customer decides to check out he/she goes to the "purchase" page where he/she can pay the total amount of the shopping cart in three different ways:
- using a credit voucher
- using a credit already charged on the smartcard
- using a credit card (accepted credit cards are. Visa, MasterCard and Great Wall Card)
The customer can logout from both the “select” and “purchase” pages. In this case no purchase is made.
You decide to apply a blended risk-based and reactive testing strategy and the following is a subset of the exit criteria for system testing:
EXCR1- Each “critical” quality risk item must be covered by at least one test condition
EXCR2- Each “critical” requirement must be covered by at least one test condition
You are following a risk-based testing strategy. The test execution time is very limited.
Assume that all the product risk items require more or less the same level of test effort.

Question No : 14

Assume that you are the Test Manager for a small insurance application development project.
You have decided to adopt a risk-based testing strategy: 5 product risks (R1, R2, R3, R4, R5) have been identified and their levels of risk have been assessed. 10 test cases (T1, …, T10) have been designed to cover all the product risks.
The following table shows the risk level and the test cases associated to the identified product risks (higher risk level means higher risk):
You are not confident with the assessment of the risk level and you suspect that it will be possible to find high-priority bugs in low-risk areas.

Furthermore the period for test execution is very short. Your goal is to test all the product risks in a risk-based way, while assuring that each product risk gets at least some amount of testing.
Which of the following answers describes the best test execution schedule in this scenario? K3 2 credits

A.T1, T2, T3, T4, T5, T6, T7, T8, T9, T10
