ISTQBw Certified Tester Foundation Level (Syllabus 2018. English) provided by iSOl GmbH, international Software Quality Institute Question 25 of 40 | Level: K3 | Number of correct answers: 1 I Credits: 1 Given the following stale model of sales order software:

Which of the following sequences of transitions provides the highest level of transition coverage for the model (assuming you can start in any state)?

APLACED --> CANCELLED ~> PLACED -> CANCELLED --> PLACED --> IN PRODUCTION --> CANCELLED

BPLACED --> IN PRODUCTION --> SHIPPED --> CANCELLED --> PLACED

CIN PRODUCTION -> SHIPPED -> INVOICED -> CANCELLED -> PLACED -> IN PRODUCTION

DIN PRODUCTION -> CANCELLED -> PLACED --> IN PRODUCTION -> CANCELLED --> PLACED

Show Suggested Answer

Suggested Answer: C

it provides the highest level of transition coverage for the model.Transition coverage is a white-box test technique that focuses on the percentage of transitions that have been exercised by a test suite1. In this case, the model is a state transition diagram that shows the possible states and transitions of a sales order software. The diagram has five states: PLACED, IN PRODUCTION, SHIPPED, INVOICED, and CANCELLED. The diagram has nine transitions: PLACED to IN PRODUCTION, PLACED to CANCELLED, IN PRODUCTION to SHIPPED, IN PRODUCTION to CANCELLED, SHIPPED to INVOICED, SHIPPED to CANCELLED, INVOICED to CANCELLED, CANCELLED to PLACED, and CANCELLED to IN PRODUCTION. Option C covers all nine transitions in the following sequence:

IN PRODUCTION -> SHIPPED

SHIPPED -> INVOICED

INVOICED -> CANCELLED

CANCELLED -> PLACED

PLACED -> IN PRODUCTION

Option A covers only six transitions in the following sequence:

PLACED -> CANCELLED

CANCELLED -> PLACED

PLACED -> IN PRODUCTION

IN PRODUCTION -> CANCELLED

Option B covers only five transitions in the following sequence:

PLACED -> IN PRODUCTION

IN PRODUCTION -> SHIPPED

SHIPPED -> CANCELLED

CANCELLED -> PLACED

Option D covers only four transitions in the following sequence:

IN PRODUCTION -> CANCELLED

CANCELLED -> PLACED

PLACED -> IN PRODUCTION

Therefore, option C is the correct answer.Options A, B, and D are incorrect, as they do not cover all the transitions in the model. Reference:1, Section 4.2.2

I practiced a question like this before, and I think option A had a lot of transitions too, but I'm not completely confident about it.

I feel like option C has a good flow through the states, but I can't recall if it really maximizes the transitions as required.

I think option B might be the right choice since it seems to cover more states, but I could be mixing it up with a similar practice question.

I remember we discussed transition coverage in class, but I'm not sure which sequence covers the most transitions here.

I'm feeling pretty confident about this one. I think option C is the way to go - it covers all the transitions in the state diagram, so it should give me the highest level of transition coverage.

Okay, I've got a strategy here. I'm going to try to find the sequence that covers each transition at least once, since that should give me the highest level of transition coverage. Let me work through the options and see which one looks best.

Hmm, this is a tricky one. I'm not entirely sure how to approach it, but I think I'll start by trying to identify all the possible transitions in the state diagram and see which sequence covers the most of them.

This question is testing my understanding of state transition coverage. I'll need to carefully analyze the state diagram and consider which sequence of transitions would cover the most unique transitions.

Wasn't there a practice question that discussed solar power? I feel like Cisco's commitment to solar energy plays a role, but I can't recall the exact percentage.

Option C looks pretty comprehensive, but I'm not sure if it's the absolute highest level. Gotta think this through carefully.

Option A looks good too, but I'm not sure if it's the highest level. Maybe we should think about the number of unique transitions covered.
