De-Stress Yourself

Hi ,

 

Slightly lengthy one, but very interesting about software testing. All
characters are imaginary.  Read through and enjoy.

A  university  scholar,  Mr.  John  Smith  approaches his friend a software
testing  guru  telling  him  that he has a Bachelor in programming, and now
would like to learn
software  testing to complete his knowledge and to find a job as a software
tester.  After  summing him up for a few minutes, the software testing guru
told him
"I  seriously  doubt  that  you are ready to study software testing. It's a
very  serious  topic.  If  you wish however, I am willing to examine you in
logic, and if you pass the test I
will help teach you software testing. "

The  young  man agrees. Software testing guru holds up two fingers "Two men
come  down  a  chimney. One comes with a clean face and the other comes out
with a
dirty face. Which one washes his face?

The  young  man  stares  at  the  software testing guru. "Is that a test in
Logic?"
software testing guru nods.

"The one with the dirty face washes his face" He answers wearily.

"Wrong.  The  one  with  the clean face washes his face. Examine the simple
logic. The one with the dirty face looks at the one with the clean face and
thinks his face is clean. The one with the clean face looks at the one with
the dirty face and thinks his face is dirty. So the one with the clean face
washes his face."

"Very clever" Says Smith.  "Give me another test"

The  software  testing guru again holds up two fingers "Two men come down a
chimney.  One  comes  out  with a clean face and the other comes out with a
dirty face. which
one washes his face?

"We  have  already established that. The one with the clean face washes his
face"

"Wrong.  Each  one  washes his face. Examine the simple logic. The one with
the  dirty face looks at the one with the clean face and thinks his face is
clean. The one
with  the  clean  face  looks at the one with the dirty face and thinks his
face is dirty. So the one with the clean face washes his face. When the one
with  the  dirty face sees the one with the clean face washing his face, he
also washes his face. So each one washes his face"

"I  didn't  think  of that!" Says Smith. " It's shocking to me that I could
make an error in logic. Test me again!."

The  software  testing  guru  holds  up  two  fingers  "Two men come down a
chimney.  One  comes  out  with a clean face and the other comes out with a
dirty face.
 Which one washes his face?

"Each one washes his face"

"Wrong. Neither one washes his face. Examine the simple logic.
The one with the dirty face looks at the one with the clean face and thinks
his  face  is  clean. The one with the clean face looks at the one with the
dirty  face  and thinks his face is dirty. But when the one with clean face
sees  that  the  one  with  the  dirty  face doesn't wash his face, he also
doesn't wash his face So neither one washes his face"
Smith  is desperate. "I am qualified to study software testing. Please give
me one more test"

He  groans  when  the  software testing guru lifts his two fingers "Two men
come  down  a  chimney. One comes out with a clean face and the other comes
out with a dirty face. Which one washes his face?

"Neither one washes his face"

"Wrong.  Do  you  now  see,  John,  why  programming  knowledge alone is an
insufficient  basis  for  studying   software  testing?  Tell me, how is it
possible for two men to come down the same chimney, and for one to come out
with a clean face and the other with a dirty face? Don’t you see? The whole
question is - foolish – and if you spend time allowed for testing trying to
answer foolish questions, all your testing will be foolish."
