Code refactoring : a Python example

Figielska Ewa

Zeszyty Naukowe Warszawskiej Wyższej Szkoły Informatyki

2022

nr 27

39--56

In this paper, several refactoring techniques are shown, using an example in which the design of a program for solving a simple problem is gradually improved. Before introducing any change to the program, the drawbacks of its current version are discussed, bad code smells are identified, and some unit tests are provided. The source code is written in Python.

There has been a lot of software design concerns in recent years that come under the code smell. Android Applications Developments experiences more security issues related to code smells that lead to vulnerabilities in software. This research focuses on the vulnerability detection in Android applications which consists of code smells. A multi-layer perceptron-based ANN model is generated for detection of software vulnerabilities and has a precision value of 74.7% and 79.6% accuracy with 2 hidden layers. The focus is laid on 1390 Android classes and involves association mining of the software vulnerabilities with android code smells using APRIORI algorithm. The generated ANN model The findings represent that Member Ignoring Method (MIM) code smell shows an association with Bean Member Serialization (BMS) vulnerability having 86% confidence level and 0.48 support value. An algorithm has also been proposed that would help developers in detecting software vulnerability in the smelly source code of an android applications at early stages of development.

Zasady, heurystyki oraz skazy w projektowaniu zorientowanym obiektowo

Artykuł omawia różne odmiany dobrych praktyk, które mają zastosowanie w projektowaniu zorientowanym obiektowo – heurystyki, zasady, skazy oraz wzorce. Na tej podstawie przedstawione zostają główne modele jakościowe projektu, tzw. modele FCM (ang. Factor-Criteria-Metric). W pracy zawarte są również metody pomiaru i identyfikacji problemów związanych z wymienionymi praktykami.

Article describes different kinds of best practices which are used in the object oriented software design – heuristics, principles, smells and patterns. Based on that, there are presented main project quality models the so-called FCM (FactorCriteria-Metric) models. Additionally the measurement and problem identification connected with the mentioned best practices is discussed as well.
