Quite oftentimes I have mails from friends bespeak for some testing exercises. According to me, if you lot are alarm enough, you lot tin dismiss honor lots of testing exercises inward your solar daytime to solar daytime life. Can’t grip amongst me? Read on…
Today I got an SMS (Forward of course) from a friend. The content of that message was every bit follows:
“If you lot are forced to depict coin past times a robber inward an ATM, thence but travel inward your PIN position out inward contrary order. By doing so, you lot volition survive allowed to remove coin from you’re a/c as well as at the same fourth dimension the cop volition survive informed! So the cop volition make the ATM inward a curt spell as well as rescue you.”
At offset sight, this mightiness seem a really useful message. But a tester is e'er trained as well as taught to survive skeptical most everything. And I am no exception. So how could I convey this slice of information every bit true, without making farther observations/investigations?
So I position on my tester’s shoes as well as tried to analyze it. And hither are my observations:
1. If this was true, thence I should have got known this before. Because, if it was true, the banking enterprise should have got informed me most this when I created my a/c as well as was given my ATM card. How could they immature lady to transfer such an of import instruction?

2. There are hundreds of banks basis over. But this SMS never told most the banking enterprise which provides this facility. That meant this information was for certain incomplete (if non incorrect).
3. Now coming to the free link of the message. At some point, the SMS tells most entering contrary PIN position out inward lodge to activate some safety system. At offset sight, this sounds similar a vivid method. Isn’t it? But but recollect for a while, as well as you lot volition know this can’t survive right. If this was true, thence how most the PIN numbers similar 1001, 2002, 1221, 2332, 1111, 2222 as well as thence on… (Palindromic Numbers) (these are my examination data). If my PIN is i of those palindromes, thence how to activate that safety mechanism? Then I persuasion i operate but about for this is to disallow Palindromic numbers every bit your PIN. But the persuasion itself sounded stupid. Simply because, at that topographic point are lots of Palindromic numbers inside 9999 (the maximum possible PIN Number). And I have got never seen a message inward an ATM machine restricting me from using a Palindromic position out every bit my PIN. But I did non desire to believe that declaration of mine, without genuinely seeing (executing my examination illustration amongst my pre-set examination data) it. So I straightaway rushed to my nearest ATM counter as well as tested this. And I constitute that at that topographic point is no such restriction for such numbers (test illustration passed!). Then I checked the same examination amongst 2 other banking enterprise a/c ATMs (regression testing!). And every bit expected hither also my test cases passed! This examination almost made me certain most the inaccuracy of the SMS message.
4. Just every bit some additional arguments to strengthen my point, I i time again looked at the SMS again. And at that topographic point it is. If at all nosotros convey this message to survive true, all the same thence create you lot recollect that “the cop volition make the ATM in a curt while as well as rescue you”, keeping inward heed that this is India?
There are all the same lots of information left inward the message which bear witness that the information is a hoax. So I would similar to larn out them for my readers as well as would similar to see, how they purpose their testing skills to honor them out.
Hints: Always purpose the iii basic weapons of a tester. i.e. Observe, Analyze as well as survive Skeptical.
There are lots of testing exercises lying but about loosely inward your ain life too. Try to position them as well as endeavour to examination them using your really ain testing skills.
Happy Testing…
