A testing puzzle that asks you identify the problem

Hi Reader,

Last week I discovered a problem I was facing at office and framed it as a puzzle that can help testers in thinking and encourage them to refine their approach to solve any such problems in testing.

There were a couple of Indian testers who took part in it and now would like to share it with you too, for a reason which I have listed below.

In order to know what the puzzle is : Testing Puzzle at office!

Now, you might wonder how important is this to you but you might find it interesting when you know from me that James Bach did crack the puzzle I put up.

Spend time solving the puzzle and if you think you have cracked the puzzle, try looking at the answer in the same blog. ( have a look at the answer only after you make an attempt cracking the puzzle )
Answer: Answering the Telephone puzzle

Good luck and kudos to those who crack the puzzle!

Thanks and Regards,
