Design Patterns in Software Maintenance: An Experiment Replication at UPM - Experiences with the RESER'11 Joint Replication Project

Abstract

Abstract-Replication of software engineering experiments is crucial for dealing with validity threats to experiments in this area. Even though the empirical software engineering community is aware of the importance of replication, the replication rate is still very low. The RESER'11 Joint Replication Project aims to tackle this problem by simultaneously running a series of several replications of the same experiment. In this article, we report the results of the replication run at the Universidad Politécnica de Madrid. Our results are inconsistent with the original experiment. However, we have identified possible causes for them. We also discuss our experiences (in terms of pros and cons) during the replication.

Proposed Automated Framework to Select Suitable Design Pattern

“…It is extremely beneficial for the developers to adopt common sense approach to select suitable pattern. Prechelt and Liesenberg [18], Juristo and Vegas [19], Nanthaamornphong and Carver [20] and Krein et al [21] repeat the same research setting that is conducted for experiment name PatMain in [17] to generalize the results but with a different tool. Thirteen students take part in the case studies those are conducted by Prechelt and Liesenberg [18].…”

“…Thirteen students take part in the case studies those are conducted by Prechelt and Liesenberg [18]. Two case studies are performed by Juristo and Vegas [19] to develop two software systems. The results are replicated that are produced in PatMin [17] to confirm the validity of research.…”

“…The results are replicated that are produced in PatMin [17] to confirm the validity of research. Juristo and Vegas [19] [20] include eighteen students in the case study. Nanthaamornphong and Carver [20] results are dissimilar from the results of PatMin [17].…”

Quantitative analysis of fault density in design patterns: An empirical study

“…Another four replications for this experiment were conducted in several universities [42]. In each replication, different findings on the impact of DPs on maintainability were reported: negative impacts [27,31,41] and no impact [36]. Garzas et al [16] investigated the impact of three different DPs on maintainability as well.…”

A Comparative Literature Survey of Design Patterns Impact on Software Quality

“…Due to the small size of the experiment they found only one statistically significant result: the non-pattern based version of only one system was more maintainable and can be extended easily. Juristo and Vegas [4] also conducted another replication study for Prechelt et al [1]. They addressed three different patterns: Abstract Factory, Composite and Decorator.…”
