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

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.

Let's go with option C then, it seems to provide the highest level of transition coverage.

The question seems straightforward, but I'm not sure which sequence provides the highest level of transition coverage.
