Problems using Code Bad Smells An overview of the empirical study Code Bad Smell detection Fault identification Result and discussion Conclusion Q/A Code Bad Smells The 22 Code Bad Smells are bad structures in source code informally identified by Fowler et al. (1999). Fowler et al. (1999) suggest that Code Bad Smells can give “indications that there is trouble that can be solved by a refactoring”. They are widely used for detecting refactoring opportunities in software (Mens and Tourwe, 2004). Problems in Using Code Bad Smells Fowler et al. (1999) claim that Code Bad Smells are structures which cause detrimental effects on software. However, little empirical evidence has been provided. Most existing Code Bad Smell detection tools are Metric-based. We argue about their accuracy. An Empirical Study of the Relationship between Code Bad Smells and
