Exam CTAL-TA_Syll2012: ISTQB Certified Tester Advanced Level – Test Analyst (Syllabus 2012)

Which of the following orthogonal arrays is to be selected for testing the house insurance policies?

A company offering house insurance policies has several policy options. They depend on the
following factors:
– Building type: house, semi-detached, apartment building, cottage
Material: wood, concrete, brick, mixed
Location: city, suburb, countryside, wilderness
It has been decided to use the pair wise test technique and apply 2-wise coverage. To design the
test case an appropriate orthogonal array needs to be located.
Which of the following orthogonal arrays is to be selected for testing the house insurance policies?

A)

B)

C)

D)

What is the correct order of the above mentioned process steps?

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?

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
How many test cases will be needed to achieve minimum coverage?

How many test cases will be needed to achieve full coverage both for valid and invalid situations?

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?
