Topic #: 2

A booking system for a city bus service prices its fares according to the time of travel:

* Off-peak tariff applies during all other times of service

* The bus service does not operate between 2300 and the start of the next day's peak service

Note that all times mentioned are inclusive.

When applying the equivalence partitioning test design technique, which of the following options, shows test case inputs that each fall into a different equivalence partition?

A0600, 1000, 1200

B1001, 1300, 2259

C0100, 0800, 2200

D2400, 1000, 2301

I appreciate how B cleanly separates the different fare periods. Makes it easy to test the system's behavior.

Haha, D is just trying to be tricky with the 2400 time - nice try, but I'm not falling for that one!

Hmm, I was stuck between B and C, but B does a better job of hitting those critical time slots. Good call.

Because the times in option C fall into different equivalence partitions - off-peak, peak, and outside of service hours.
