+00:00:00,230 --> 00:00:03,250
+Now we move to the next step, which involves partitioning the
+
+2
+00:00:03,250 --> 00:00:07,680
+categories that we just identified into choices. 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.
