Testers Logical Thinking...

Its important for Testers to have good logical thinking skills.

I would like to illustrate it with a nice example:

Precondition: Lets assume that we have four cards and each card has a alphabet on one side and a numeric on the other side.

Requirement: The card which has 7 on one side must have a D on the other side.

Below are the cards in order:

D, 7, A, 4

Question: To test the above requirement, what cards need to be flipped out of the 4 given above?

Answering the above question helps us in deriving scenarios, Best suite to test(pair wise) etc.

Also as we know proper set of scenarios helps in reducing effort spent in prep,execution, redundancy etc.

Please post comments if you like it.
