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?
