Assume you have some data related to confirmation testing during system testing of a past project.
In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three times and no bug reports have been opened more than three times.
You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 personhours.
Which of the following statements correctly describe the value of these confirmatory testing activities based on cost of quality?

Assume you are currently working on a project developing a system where functional
requirements are very well specified. Unfortunately non-functional requirements do almost not exist.
You are the Test Manager. You have to choose a technique for test selection that allows testing of non-functional characteristics, especially reliability.
Which of the following techniques for test selection do you expect being most useful in this scenario?

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
The following is the unique ''critical'' quality risk item that has been identified:
CR-RSK-1. The GUI of the application might accept non-integer values for the input field designed to get the number of bottles from the user
Test analysis for system testing has just begun and the following test conditions have been identified.
TC-SEL-2. Test the selection of the package sizes
TC-SEL-4. Test wrong numbers of bottles for an order
TC-CR-RSK-1. Test the accepted values from the input field designed to get the number of bottles from the user
What is the MINIMUM number of test conditions that must be added to fulfill both the EXCR1 and EXCR2 exit criteria?

Answer : A
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.

Which of the following answers describes the best execution schedule in this scenario? K3 3 credits
Answer : D

Assume you are managing the system testing phase of a project.
The system test execution period is scheduled to twenty weeks.
All tests are manual tests. You are following a risk-driven test approach.
During the last staff meeting the project manager tells you new deadlines that will not allow completion of all the system tests.
Which of the following would you expect to be the best way to respond to this situation? K2 1 credit
