When learning about software testing within a life-cycle of a software product, I have come across special-purpose implementation of software components in existing software products, or stubs. this has provided me with a different approach to writing my blog whereby I list 'blog stubs' to expand on, which, I am finding, is very conducive to the way I think in relation to Asperger's Syndrome in a visual and structural sense. The list of blog stubs provides me with a structure, giving me a visual image as to how paragraphs and content will be structured, as well as occasionally enabling me to come up with an image to explain what I am writing about. Autism Works' Test Manager Grayson Cobb did this very effectively in explaining the techniques of statement and branch testing coverage using an image of three pies, to explain the workings of the following code:
If A = 3 then
If B = 2 then
Unless one has an IT background, the above code is unlikely to make sense initially, as much as it didn't to me, not to mention the relationship with the pies! The first two actions (A=3 and B=2) are both specific and have an equally specific outcome while the next two actions (else) are open. So to do a 'statement test' to ensure the specific actions work you would need to test two actions (A=3 and B=2), but to do a 'branch test', you would need to test all actions. How this works in relation to the pies is that of the three pies, one is mince and the other two are steak, but is unknown which is which, so one would have to taste all three pies to see which one was mince and which two were steak, performing three tests. It became much clearer to me after Grayson used his previous experience as a chef in explaining the process!
Many people with Asperger's Syndrome and High-Functioning Autism, including myself and, perhaps most famously, Temple Grandin are largely visual thinkers, often benefiting from use of images to understand different working processes, hence the title of one of Temple Grandin's best known works Thinking in Pictures. In relation to how I think visually, I find it especially helpful when learning a new theory or task, in this case a software testing technique, it helps to use an effective visual image or to act a task out enabling me to see the workings of it, and so that I am able to replicate the task effectively.
