JANE COACHING SIMON ON ORACLES
(An oracle is a principle or mechanism used to detect a problem)
Simon: In my point of view testing is trying out a system and his functions to see if it works as expected by somebody Jane: what do you mean by "see if it works as expected"? Simon: checking against somebodies requirements: that can be a specification, User Stories, Acceptance criteria, prototype..... Simon: I just read today the "Testing without a map" by MB - so there he explains the ORACLE Jane: how does that fit into to what we are discussing? Simon: checking against an oracle....which provides the right answer of a requirement from somebody would that be correct? in your view? Jane: what is an oracle? Simon: source of THE right answer
What will Jane do next?
Click and hold the red square. Now, move it so that you neither touch the walls nor get hit by any of the blue blocks If you make it to 18 seconds, you are doing brilliantly!
JANE: TELL ME YOUR TESTS
What will Jane do next?Jane: is your test an important test?
Simon: yes Jane: why? Simon: main functionality in my point of view - hit the wall or get hit by the blue squares - quits the game
Simon: I tested if touching the walls or get hit by the square blue rocks by moving around the red square, quits the game and yes it does. So I was testing the description of the game
IS IT A BUG? Jane: who says it quits the game - how do you know its not a bug? Simon: you are right, it could be a bug... Jane: what do you think? Is it a bug? Simon: I don't know - missing specification ;) Jane: you seem to think that without a spec your unable to determine if this is a bug or not Simon: no no Jane: well then, is it a bug? Simon: yes, nothing says that the game has to be quit Jane: so its a bug Simon: yes
SERIOUSLY, IS IT A BUG?Jane: why is it a bug? Simon : :D Simon : that I call CHALLENGING Simon : wow Jane : What's challenging? Simon: your questions Jane: what we are looking at here is an example of a unidentified oracle Simon: ahhh Jane: you think its a bug, but you're unable to explain why you think its a bug Jane: because you don't know the oracle you are using Simon: yes
DEBRIEF
Jane: you mentioned that an oracle was a source of the right answer Jane: it is the source but also its how you apply that source in your testing Simon: ahh Jane: an oracle is a principle or mechanism used to *recognise* a problem Jane: requirements on their own are just that - they are a source of knowledge Jane: its only when you compare and evaluate your product against the requirements that they become an oracle Jane: you *use* them to recognise a problem Simon: ahh, so requirements are becoming oracles... Jane: yes
DEBRIEF (CONTINUED)
Jane: its like saying "water puts out fires" - well ...yes it does....but Jane: its useless unless someone pours water over the fire Jane: I mean it could be sitting in a bucket beside the fire Jane: people could use it to wash their hands and all Jane: all very useful , but its not putting out the fire Simon: so oracles have to be applied... Jane: yes exactly! Simon: wow great!
HOMEWORK SET
Jane: but I want you to think about why you think you're bug is a bug Jane: what oracle are you using Jane: but to be an excellent tester you need to be comfortable with these terms and be able to apply them in your testing Jane: I look forward to your email Simon: ok Jane: bye for now and thanks for contacting me. IT was a pleasure! Simon: I have to thank YOU - for your precious time which you spent by coaching me
HOMEWORK
I thought ...& I feel confident that this isn’t a bug finally. The oracle I’m using when there is no specification .. and I can’t decide whether it works properly according to someone, I should test this functionality according to “What could be the users’s expectations”. So I’m using an oracle which may sound “a functionality should behave consistently with my understanding of what the user reasonable expectation might be.” I checked the behaviour game quits now against the oracle and come to the result, that from my point of view the oracle is fulfilled à conclusion: the “game quits” works as the user would expect, so this isn’t bug.
