agile software development principles patterns and practices

The design pattern mentioned here is the pattern in software design, mainly refers to the object-oriented software design. Compliance with the design model can effectively improve the maintainability and reusability of software, improve the efficiency of 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

JavaScript design patterns and development practices-JavaScript Polymorphism "Polymorphism" is derived from polymorphism in the Greek text. The split is poly (plural) + morph (morphology) + ism, which can be literally understood as the plural form. The actual meaning of polymorphism is: the same operation acts on different objects and can produce different interp

factors also on the results haveVery big impact. However, as programmers grow in maturity, TDD is able to help programmers find more problems before they are delivered to QA, or to stifle defects in TDDRing process.AnywayTypically, the project itself is developed much less than its long-term operational use time, and changes in demand as the business grows, as programmers become more adept at using TDDand team agility maturity, which can be earned by reducing the time of defect modification and

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

Read the JavaScript design patterns and development practice today and have long been eager to learn about design patterns. The design pattern is defined as a simple and elegant solution to a particular problem in the object-oriented software design process. In fact, usually in the work unconsciously in t

programmers may consider some of the functions that this class may need. At this time, you should add these considerations as comments, but never write any code, until these potential features are actually needed; L never add a data member before a use case actually needs it This is recommended to be the same as the previous one, but its object becomes a data member of the class. Sometimes it may seem obvious that a "user" record will be used somewhere; but you should never add that data me

through a series of sprints, which is similar to the iteration of extreme programming. The Scrum project process consists of a series of sprints. A Sprint is usually 2-4 weeks in length. It is a time box and cannot be extended or shortened during the project. A stable cycle will bring a better pace A Sprint consists of Sprint planning meetings, development work (requirement analysis, design, development

the adorner mode is intended to add functionality to the Object. The decorator pattern often forms a long decorative chain, while the adapter pattern is usually packaged only once. The proxy mode is to control access to objects and is usually wrapped only once. The function of the appearance mode is similar to the adapter, Some people regard the appearance pattern as the adapter of a set of objects, but the most notable feature of the appearance mode is the definition of a new interface.
