The quest for improving the software quality has given rise to various studies which focus on the enhancement of the quality of software through various processes. Code smells, which are indicators of the software quality have not been put to an extensive study for as to determine their role in the prediction of defects in the software. This study aims to investigate the role of code smells in ...

Context: Code smells are indicators of poor coding and design choices that can cause problems during software maintenance and evolution. Objective: This study is aimed at a detailed investigation to which extent problems in maintenance projects can be predicted by the detection of currently known code smells. Method: A multiple case study was conducted, in which the problems faced by six develo...

Code smells are indicators of software design shortcomings that can decrease software maintainability. An advantage of code smells over traditional software measures is that the former are associated with an explicit set of refactoring strategies to improve the existing design. As such, code smell analysis is a promising approach to address both the assessment and the improvement of maintainabi...

Code smells are structured characteristics of software that may indicate a code or design problem.It makes a software hard to evolve and maintain and may trigger refactoring of code.It have a different types of code smells,refactoring tools,but it doesn’t know the sequence of code smells to be resolved first.Identifying and detecting the code smells are performed rarely because all types in the...

s, titles and keywords were analysed by VOSviewer using default parameters. All common terms like study, baseline, control group, trend, method were excluded from the analysis. Three maps were induced (1) clustered landscapes presenting popularity of terms (more popular terms are presented in larger squares), associations between terms (terms locted near each other are stongly associated) and r...

Today, test suites of several ten thousand lines of code are specified using the Testing and Test Control Notation (TTCN-3). Experience shows that the resulting test suites suffer from quality problems with respect to internal quality aspects like usability, maintainability, or reusability. Therefore, a quality assessment of TTCN-3 test suites is desirable. A powerful approach to detect quality...

Code smells reflect sub-optimal patterns of code that often lead to critical software flaws or failure. In the sameway, community smells reflect sub-optimal organisational and socio-technical patterns in the organisational structure of the software community. To understand the relation between the community smells and code smells we start by surveying 162 developers of nine opensource systems. ...

In computer programming, code smell may origin of latent problems in source code. Detecting and resolving bad smells remain time intense for software engineers despite proposals on bad smell detecting and refactoring tools. Numerous code smells have been recognized yet the sequence in which the detection and resolution of different kinds of code smells are performed because software engineers d...

Code smells are manifestations of design flaws that can degrade code maintainability if left to fester. The research in this paper investigates the potential of code smells to reflect system-level indicators of maintainability. We report a study where the strengths and limitations of code smells are evaluated against existing evaluation approaches. We evaluated four medium-sized Java systems us...
