A survey on software coupling relations and tools

Abstract

Context: Coupling relations reflect the dependencies between software entities and can be used to assess the quality of a program. For this reason, a vast amount of them has been developed, together with tools to compute their related metrics. However, this makes the coupling measures suitable for a given application challenging to find. Goals: The first objective of this work is to provide a classification of the different kinds of coupling relations, together with the metrics to measure them. The second consists in presenting an overview of the tools proposed until now by the software engineering academic community to extract these metrics. Method: This work constitutes a systematic literature review in software engineering. To retrieve the referenced publications, publicly available scientific research databases were used. These sources were queried using keywords inherent to software coupling. We included publications from the period 2002 to 2017 and highly cited earlier publications. A snowballing technique was used to

Reusability affecting factors and software metrics for reusability: A systematic literature review

“…Moreover, we followed the recommendation presented in Brereton et al 28 and Staples and Niazi, 29 which are widely used to conduct SLRs in the software engineering domain. In this section, we have used some of the figures and review design inspired by Fregnan et al 21 and Unterkalmsteiner et al 30 The work by Kitchenham proposes three phases in SLR, including planning, conducting, and reporting, as shown in Figure 2. These three stages are explained in detail.…”

How the Experience of Development Teams Relates to Assertion Density of Test Classes

“…Also in this case, we computed LCOM5 on test classes too: indeed, low cohesion of tests has been shown to be an important factor for test effectiveness [52], [53], i.e., test.lcom; Coupling. Production classes having a high level of coupling tend to be less maintainable [42], [54]. As a result, the corresponding test classes might require more assert statements in order to carefully verify the behavior of the tested code.…”

Simplifying the Structural Complexity of Software Systems

“…A Coupling is a controlling mechanism which assesses relations between the components of a software system [10]. The objective is to enable users to understand how a system component relates to other components prior to any modification is being considered.…”
