Programming and Interface Design

(a) Defifine brieflfly, for every one of the accompanying procedures, what its motivation is and how

it is led.

(I) Regression testing

(ii) A/B testing

(iii) Unit testing

(iv) Load testing

[12 marks]

(b) Although every one of these methods can give new data of significant worth to a

programming project, expenses can be decreased in the event that data is accessible prior in the

configuration cycle. For every one of the four procedures partially (a), recommend a strategy by

which a portion of the subsequent data could be acquired before in the task.

Programming and Interface Design

Coming up next is a concentrate from a plan brief composed by the client for one of the

2014 Cambridge bunch configuration projects.

What I'd like is some kind of data set of plans to which I can send inquiries such

as "Observe me something that doesn't contain cabbage or tomatoes that takes not exactly

30 minutes to get ready", or "I have kohlrabi in the veg box AGAIN, are there any

plans I haven't attempted that could make something consumable out of it?", or "I've in fact

got several hours allowed to cook this end of the week, what was that muddled Ottolenghi

formula I flflagged fourteen days prior to attempt later?". The data set necessities to adapt to the reality

that fixings can have difffferent names yet mean exactly the same thing: for example "flflour" and

"plain flflour", and that "1/4 lb" and "4oz" are exactly the same thing and equivalent to "100g"

(also, not 113g). It would be incredible if whenever I've picked the current week's menu, it could

produce a shopping list I can plug into www.myfavouritesupermarket.com, and it

should be usable by non-engineers.

(a) For every one of the accompanying programming project stages, recommend a plan model or

portrayal that would be a useful guide in the plan cycle. For each of

these, sketch a guide to show what this model resembles, in view of some part

of the above plan brief.

(I) Inception stage

(ii) Elaboration stage

(iii) Construction stage

(iv) Transition stage

[12 marks]

(b) For every one of the outlined models to some degree (a), depict how the plan work so

far could be assessed prior to continuing to the following stage. [4 marks]

(c) Choose two of the above plan models, portrayals or assessment techniques,

furthermore, make sense of how they would be done difffferently assuming the plan project was

following a light-footed instead of winding venture the executives approach. [4 marks]
