And this - -3 -00:00:06,300 --> 00:00:08,470 -is a group of software development methods that are - -4 -00:00:08,470 --> 00:00:12,620 -based on highly iterative and incremental development. And in particular, - -5 -00:00:12,620 --> 00:00:16,000 -I'm going to discuss Test Driven Development or TDD. The - -6 -00:00:16,000 --> 00:00:18,490 -space on the iteration of three main phases. In - -7 -00:00:18,490 --> 00:00:20,970 -the first one that we mark as red, we - -8 -00:00:20,970 --> 00:00:25,350 -write test cases that encode our requirements, and for which - -9 -00:00:25,350 --> 00:00:29,180 -we haven't written code yet. And therefore, they will fail, obviously. - -10 -00:00:29,180 --> 00:00:31,800 -So we're in this sort of red or fail phase. From - -11 -00:00:31,800 --> 00:00:34,830 -this phase, we move to this phase, in which after we - -12 -00:00:34,830 --> 00:00:37,970 -write the just enough code to make the test cases pass. - -13 -00:00:37,970 --> 00:00:40,670 -We have a set of test cases that are all passing. - -14 -00:00:40,670 --> 00:00:43,810 -And therefore, we can consider this as the green phase. We - -15 -00:00:43,810 --> 00:00:46,930 -had enough code to make the test cases pass because the - -16 -00:00:46,930 --> 00:00:50,520 -test cases encode our requirements. We have just written enough code to - -17 -00:00:50,520 --> 00:00:53,940 -satisfy our requirements. When we do this over time though, - -18 -00:00:53,940 --> 00:00:57,080 -what happens is that the structure of the code deteriorates, because - -19 -00:00:57,080 --> 00:00:59,100 -we keep adding pieces. So that's why we have the - -20 -00:00:59,100 --> 00:01:02,540 -first step, which is refactoring. In this step, we modify the - -21 -00:01:02,540 --> 00:01:05,724 -code, and we will talk about refactoring extensively. We'll devote - -22 -00:01:05,724 --> 00:01:08,190 -one lesson to it. We modify the code to make it - -23 -00:01:08,190 --> 00:01:12,650 -more readable, more maintainable. In general, we modify to improve the - -24 -00:01:12,650 --> 00:01:15,560 -design of the code. And after this phase, we will go - -25 -00:01:15,560 --> 00:01:17,670 -back to writing more test cases for - -26 -00:01:17,670 --> 00:01:19,730 -new requirements, write code that makes these - -27 -00:01:19,730 --> 00:01:24,870 -test cases pass, and so on. So we'll continue to iterate among these phases. And - -28 -00:01:24,870 --> 00:01:26,500 -also, in this case, we will talk - -29 -00:01:26,500 --> 00:01:29,390 -about Agile Software Processes. And in particular, - -30 -00:01:29,390 --> 00:01:32,250 -about extreme programming, or XP, and Scrum - -31 -00:01:32,250 --> 00:01:35,349 -in more details, in minor course number four. -- cgit 1.4.1
