-So now let's go back to our split example. Let me - -2
-rearrange things a little bit to make more room. So now I'm - -3
-going to put the domains for size and for strength one next to - -4
-the other. So let's look at what some possible inputs will be - -5
-for the sub domains that we identified when we use the idea - -6
-of selecting input of the boundary. If we look at the first - -7
-subdomain, size less than zero, one reasonable input is, size equals to - -8
-minus 1, because minus 1 is the boundary value for the domain - -9
-of the integers less than zero. If we look at the third - -10
-subdomain, possibly interesting case is the one of size of equal to - -11
-1, for the same reasoning that we used for the previous subdomain, - -12
-for size less than zero. And, let's try to select another one - -13
-for this subdomain, for the integers greater than zero. If there is - -14
-a concept of maximal integer, we can select that one as our - -15
-boundary value. And of course we could select much more, but this - -16
-is just to give you an idea. Other possible inputs. One interesting - -17
-example for the first one, string with length less than - -18
-size will be a string with length size minus one. Again - -19
-this is the boundary value for this domain. And we could - -20
-continue in this way like for example selecting a string who's - -21
-length is exactly size as a boundary value for this - -22
-other domain. Instant one, and we look back actually to this - -23
-example and look at it in a more extensive way when - -24
-we actually talk about a specific method for doing this kind - -25
-of process. -- cgit 1.4.1
