Which of the following BEST explains the use of cause-effect graphing?

How do user stories and testing relate in an agile project?

A new banking system has 2 customers’ types, 2 account types and will operate in two different
countries?
How many test cases will be needed using the pair wise testing technique and the appropriate 2-
wise orthogonal array?

You are applying pairwise testing and using orthogonal arrays. The following steps are all part of the
process to be followed.
i) Determine the number of choices for each variable
ii) Map the test problem onto the orthogonal array
iii) Construct the test cases

iv) Identify the variables
v) Locate an appropriate orthogonal array
What is the correct order of the above mentioned process steps?

While identifying scenario’s for the use case “copy A4 – A4” for a new copier, the following
scenario’s were identified:
Basic scenario: single side to single side
Deviations: single side to double side, copy of a set, copy using the automatic document feeder
Failures: no paper in paper tray, paper jam, out of staples. How many test cases will be needed to
achieve minimum coverage?

While identifying scenario’s for the use case “copy A4 – A4” for a new copier, the following
scenario’s were identified:
Basic scenario: single side to single side
Deviations: single side to double side, copy of a set, copy using the automatic document feeder
Failures: no paper in paper tray, paper jam, out of staples During interviews with both development
and end-users it has been established that the failure scenario’s can occur during the basic scenario
and during each of the deviations.
How many test cases will be needed to achieve full coverage both for valid and invalid situations?

You are testing an ATM based on the following use case;
ATM start screen is showing
1. The user inserts card
2. The user types in PIN
3. The user selects ‘cash with receipt’
4. The user selects € 50
5. The user selects ‘no further service’
Expected results
– The ATM provides €50 to the user
– The ATM return the card and balance slip
– The ATM clears the screen
– The ATM returns to start menu
In your test log which of the following could be noted as part of additional attention points?

Supercar
Supercar is an online vehicle sales website specializing in single manufacturer’s Sports Utility
Vehicles (SUVs) and saloons. A vehicle has two key elements, power unit and body style. The
manufacturer offers three choices of power unit: petrol, diesel and hybrid. There are 3 main body
styles: Saloon, Hatchback and SUV. SUVs only come as petrol and diesel options. Hybrid is available
for Hatchback only. The site will allow an order to be processed if the chosen vehicle configurations
are in stock, otherwise a message will be displayed asking the user to try again later.
Based on the specification the following classification tree has been developed:
Based on the “Supercar” classification tree the following positive test cases have been created:
Which test case is needed to complete the set?

Tax system
A 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 cases are required
to test the “Tax system” specification using a decision table which is not collapsed?
