ISQI CTAL-TA Exam Practice Questions (P. 4)

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 scenarios 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?
