Code Smells are signals that your code should be refactored in order to improve extendability, readability, and supportability. new code smell? It makes code harder to understand and maintain. I’m just reviewing a project’s code. Each interface is only implemented by one class. Speculative Generality You get this smell when people say "Oh, I think we will need the ability to do that someday" and thus want all sorts of hooks and special cases to handle things that aren't required. approach to d etect five code bad smells after enhancing . A method that is not used anywhere in the code is known as a speculative generality code smell. Speculative Generality; Speculative generality occurs when there is unused code written to support the future needs which never got implemented. Removing code smell is an important task and can be done using automated code review tools. CCS CONCEPTS • Software and its engineering → Software evolution; KEYWORDS Refactoring, Code Smells, Structural Quality Permission to make digital or hard copies of all or part of this work for personal or Feature Envy A method accesses the data of another object more than its own data. Hinders: comprehension, maintenance Speculative Generality Every class implements an Interface. Object Refactoring Extract Class. This group contains two types of smells (dispensable classes and dispensable code), but since they violate the same principle, we will look at them together. That is, make your code meet today's requirements, and don't try to anticipate which way tomorrow's requirements will go. I don't think we should use phrases like interested, since code and machines do not have human qualities such as interest or envy. Code that was over-generalized in an attempt to predict future needs. They describe code in need of refactoring in rich language such as 'Speculative Generality', 'Inappropriate Intimacy' or 'shotgun surgery'. Fowler, ... of the operating system that the object is wrapping. Speculative Generality. Program entity (class, method, parameter, code fragment, statement, variable) that is unused in the system. Dealing with a Code Smell • Pragmatic view: Analyze each one & determine whether there really is a problem • Purist view: Get rid of it. Refactoring - code smell. Some notes to be considered during planning are: * Don’t over plan your code. This code smell is known as speculative generality. Dead Code. The tool uses a genetic algorithm (GA) to search for the best sequence of refactoring that removes the highest number of code smells from the source code. Everyone loses in the "what if.." school of design. FW: bad smell code # 5 Divergent Changes; A technic to eliminate select-case structure; technic to eliminate select-case structure - 2; Bad smell in code # 10 Select-case Statment and s... FW: Bad smell in code - Speculative Generality; FW: Bad smell in code - Speculative Generality; FW: Bad smell in code-- Temporary Fields This code smell happens when code is created, but it is not used (or not needed) because we think that “We might need this come day”. Dispensables are avoidable components whose absence would make the code much more cleaner, readable and efficient. A method that is not used anywhere in the code is known as a speculative generality code smell. PLAY. —Martin Fowler. A code smell is a surface indication that usually corresponds to a deeper problem in the system. You get it when people say, “Oh, I think we’ll need the ability to do this kind of thing someday” and thus add all sorts of hooks and special cases to handle things that aren’t required.
