And these choices are the - -3 -00:00:07,680 --> 00:00:11,930 -interesting cases for each category. So the interesting subdomains for each one - -4 -00:00:11,930 --> 00:00:14,810 -of these categories. So once more, lets look at that using our - -5 -00:00:14,810 --> 00:00:18,110 -example, the split program. So lets start by considering length. What are - -6 -00:00:18,110 --> 00:00:20,710 -the interesting cases when we think about the length of a string? - -7 -00:00:20,710 --> 00:00:23,220 -Some of those we already saw, one interesting case is the case - -8 -00:00:23,220 --> 00:00:26,190 -of the length of size zero, so a string with no characters. - -9 -00:00:26,190 --> 00:00:29,030 -Another interesting case is the one in which the length of the - -10 -00:00:29,030 --> 00:00:31,780 -string is size minus one, so the string is just one character - -11 -00:00:31,780 --> 00:00:34,610 -short of the size at which it will be cut by the - -12 -00:00:34,610 --> 00:00:38,160 -split program. And we can continue along these lines, so we will select - -13 -00:00:38,160 --> 00:00:42,950 -size, size plus one, size twice the value of size minus one, - -14 -00:00:42,950 --> 00:00:45,560 -and so on and so forth. But even without listing all of - -15 -00:00:45,560 --> 00:00:47,500 -those, I'm sure you get the idea of what it means to - -16 -00:00:47,500 --> 00:00:49,780 -identify this interesting cases. Let's see - -17 -00:00:49,780 --> 00:00:51,702 -the movements that are considering the content. - -18 -00:00:51,702 --> 00:00:53,990 -So without the interesting cases when we think about the content - -19 -00:00:53,990 --> 00:00:56,520 -of the string. So possible interesting case is the string that - -20 -00:00:56,520 --> 00:01:00,660 -contains only spaces. Why? Well maybe because a split is written - -21 -00:01:00,660 --> 00:01:04,290 -spaces in a special way. Similarly a string that contains special - -22 -00:01:04,290 --> 00:01:06,780 -characters, like non printable characters, - -23 -00:01:06,780 --> 00:01:09,020 -like tabulation characters, new line might - -24 -00:01:09,020 --> 00:01:12,240 -also be an interesting case, something that we want to test. Also - -25 -00:01:12,240 --> 00:01:14,280 -in this case we could continue and go on and on. - -26 -00:01:14,280 --> 00:01:17,250 -So basically here you just want to put all the interesting cases - -27 -00:01:17,250 --> 00:01:20,010 -that you can think of when you consider the content - -28 -00:01:20,010 --> 00:01:22,440 -of a string. Now let's move to the value as the - -29 -00:01:22,440 --> 00:01:25,740 -next category. So the value of the input size. And - -30 -00:01:25,740 --> 00:01:29,280 -here we might want to consider a size zero, special case, a - -31 -00:01:29,280 --> 00:01:33,640 -normal situation, like size greater than zero, another special case, - -32 -00:01:33,640 --> 00:01:36,420 -size less than zero or maxint. And these are, if you - -33 -00:01:36,420 --> 00:01:39,420 -remember, I accepted the cases that we consider when we look - -34 -00:01:39,420 --> 00:01:42,350 -at this example, before. And also here we can continue and - -35 -00:01:42,350 --> 00:01:43,970 -go on and on. So, at the end of the - -36 -00:01:43,970 --> 00:01:46,860 -step, what we have is a set of interesting cases - -37 -00:01:46,860 --> 00:01:49,220 -for each one of the categories, and now we can - -38 -00:01:49,220 --> 00:01:51,150 -start to think about how we want to combine them. -- cgit 1.4.1
