Scenario "Banking Project"
As a test analyst in the banking domain you have received the following requirement:
''The system shall allow cash advances of at least 200 Euros for all supported credit cards. The correct list of credit cards is American Express, Diners, VISA, Mastercard and Eurocard.
For the ATM banking project introduced earlier; ''When the user first inserts a valid credit card type, the system considers the user to be in an unauthenticated state. When requesting a cash advance, the user must be in an authenticated state. The user authenticates by entering the proper PIN code. When authenticating the user, the system shall allow the user to enter their PIN code up to three times before failing the authentication and rejecting the card. On the first and second try, the system shall prompt the user to re-enter the PIN code.'' Suppose you are concerned that, depending on the exact number of invalid PIN codes entered, the system might behave improperly. Which of the following test design techniques is specifically targeted at such failures?
Which alternative specification-based test design technique could be used to test the web site and will most likely find very different types of defects?
Using the scenario as described above, using boundary value analysis, which would be the most interesting test set to explicitly test one single boundary value as defined in the specification?
Scenario "Tax system"
The tax system needs to be updated due to new legislation. For a person with a salary of less than 20.000 and who is married, the tax needs to be re-calculated. If the person also has more than two and less than five children, an additional 10% reduction is applicable. How many input classes can be distinguished when applying equivalence partitioning to the Tax System specification?
