What create yous await spell testing? Many testers believe that spell testing, nosotros should await simply about output in addition to compare the actual output alongside the expected one! If they fit so the examination illustration passes else it fails. Quite elementary in addition to straightforward, isn’t it? I would enjoin No! I wishing testing was so simple!
What characterizes a formal, written test case is that at that topographic point is a known input in addition to an expected output, which is worked out earlier the examination is executed. The known input should test a precondition in addition to the expected output should test a postcondition. - Wikipedia
The inward a higher house is the description of a examination illustration from Wikipedia. And I am NOT going to challenge the Definition of a examination illustration inward this post. If anyone expected (did I work “expect”?) such a post, delight excuse me. :)
I am NOT against how nosotros define a examination case. But I am non certain if I actually similar the agency nosotros use/treat examination cases! I handle that nosotros should await simply about variety of output (can endure a purpose of a requirement or work illustration etc) spell testing a product. But next a strict suite of pre-defined examination illustration (be it manual or automated) mightiness number inward Inattentional blindness!
Inattentional blindness, closely related to the dependent area of alter blindness, is an observed phenomenon of the inability to perceive features inward a visual scene when the observer is non attending to them. That is to enjoin that humans accept a express capacity for attending which so limits the total of data processed at whatever detail time. Any otherwise salient characteristic inside the visual champaign volition non endure observed if non processed past times attention. - Inattentional blindness
Watch the inward a higher house video for a demonstration of Inattentional blindness. Same tin give notice occur to a tester who is looking out for an expected demeanour spell testing. There were instances when I had missed out obvious in addition to elementary to bring out bugs because I was looking for simply about complex behavior. From my ain sense I accept learnt that inward improver to expected behaviors (passing of ball!) nosotros should too decease along our eyes in addition to ears opened upwards to other unexpected behaviors (the gorilla!) that mightiness endure taking house spell conducting the test. Test cases mightiness bring out us those bugs which nosotros had planned to dig out. But I am non certain if they could bring out us whatever novel bugs that mightiness endure lurking inward the vicinity! So spell testing, ameliorate to await the unexpected in addition to human action accordingly earlier nosotros immature lady simply about other obvious looking bug! By the way, afterward all no tester would similar his manager/client to bring out such a bug!
