manifesto for agile software development

Agile requirement analysis, Agile Project Management, and agile software development have become a hot topic. In today's complex and changing business projects, it seems that "agile" has become the best choice. Indeed, no matter f

Today I am reading chapter 7 of When the software smells like any of the following, it indicates that the software is corrupt.Rigidity: it is difficult to make changes to the system, because every change forces many other changes to the other part of the system.Vulnerability: changes to the system may cause problems in many areas that are conceptually irrelevant to the system and the changes.Strong: It is d

customers and users as frequently as possible to receive feedback from them. Summary: In many aspects, OCP is the core of object-oriented design. Following this principle can bring about the great benefits that object-oriented technology claims (flexibility, reusability, and maintainability ). However, it does not mean that we follow this principle as long as we use an object-oriented speech. It is not a good concern to abstract every part of the application. The correct approach is that devel

Controller =Controller; } Public voidcoin () {State.coin ( This); } Public voidPass () {State.pass ( This); } Public voidSetlock () { state=Lockedstatus; } Public voidSetunlock () { state=Unlockedstatus; } voidthankyou () {controller.thankyou (); } voidAlarm () {controller.alarm (); } voidLock () {controller.lock (); } vo

run, the faster you will find any deviations from those tests. If you can run all the tests multiple times a day, the system will not expire for more than a few minutes. This is a reasonable goal. We will never allow the system to regress. Once it is working at a specific level, it must not be reversed to a slightly lower level.However, validation is only one of the benefits of writing tests. Both unit and acceptance tests are a form of documentation. Such a document can be compiled and execute

. Strict deadlines force you to make tough decisions without leaving long-standing issues behind.A fixed price means a betrayal of commitment.Let the guest team and the customer work together, truly in the current project to do the actual evaluation, by the customer control their function and budget.How to estimate project cost and time is another science.1. Proposed to build the system demo (to make the most important functional part), the completion of the first delivery should be no more than

and cannot be overused. If a class has hundreds of different interfaces, some of which are separated according to the client program, others are separated by version, then the class is hard to figure out, and this kind of hard-thinking is very frightening.12.5 ConclusionFat classes can cause unhealthy and harmful coupling relationships between their client programs. When a client program asks for a change to the Fat class, it affects all other client programs. Therefore, client programs should

following code: Public class base{ publicvirtualvoid f () {/*some code* / }}publicclass derived:base{ publicoverride void f () {}}The function f is implemented in base. However, in derived, the function f is degenerate. Perhaps, derived programmers think that function f is useless in derived. Unfortunately, base users do not know that they should not call F, so there is a substitution violation.The existence of degenerate functions in degenerate classes does not always mean that the LS

Whether it is in activexform or smartclient mode, the interface effect is the same, because the same service plug-in module is used, all the requiredProgramSet. Demo account online. You can use three common accounts: demo1, demo2, and demo3. You can also directly use the James Administrator Account to log on to the demo. All accounts and passwords are demo.

Code is often corrupted. With the addition of one new feature, the structure of the Code gradually degrades when an error is handled. If you ignore this, this kind of degradation will eventually lead to tangled and difficult to maintain chaotic code. The XP (eXtreme Programming) team uses regular code refactoring to reverse this degradation. Refactoring does not change. A series of small modifications are made to improve the system structure on the premise of code behavior. Every transformati

Introduced: In agile software development, the speed of code generation is much higher than that of traditional waterfall. Because we have made the time more compact. How can so much code guarantee the quality of the code? Many people may think directly of static code detection tools. Yes, those are the ones that can define a code-checking rule to ensure the qua

1. What we need to do before optimization is to satisfy our customers by delivering fat-reducing software as soon as possible and continuously. 2. Even after development, you are welcome to change your requirements. Agile processes use changes to create competitive advantages for customers. 3. The software can be del

I have been asked the same question twice recently: If a software requires a lot of Intensive design work, resulting in an independent design and development team, how should we implement agile development? On the whole, agile developme
