Hidden dependencies in program comprehension and change propagation

Zhifeng Yu, V. Rajlich
Proceedings 9th International Workshop on Program Comprehension. IWPC 2001  
It discusses the impact of hidden dependencies on the process of change propagation and also discusses an algorithm that warns about possible presence of hidden dependencies.  ...  Large software systems are difficult to understand and maintain. Program dependency analysis plays a key role in both understanding and maintenance.  ...  Section 4 defines hidden dependencies and analyzes their impact on program comprehension and change propagation.  ...

Istvan Gergely Czibula, Gabriela Czibula, Diana Lucia Miholca, Zsuzsanna Marian
2017 Studia Universitatis Babes-Bolyai: Series Informatica  
In this paper we aim to provide a comprehensive review of existing methods for hidden dependencies identification, as well as to highlight the limitations of the existing state-of-the-art approaches.  ...  There exist hidden dependencies in the software projects which cannot be found using common coupling measures and are due to the so called indirect coupling.  ...  Analyzing program dependencies has an essential role in program comprehension, change propagation, or impact analysis [22] .  ...

Variable granularity for improving precision of impact analysis

Maksym Petrenko, Vaclav Rajlich
2009 2009 IEEE 17th International Conference on Program Comprehension  
Impact analysis is a specialized process of program comprehension that investigates the nature and extent of a planned software change.  ...  In this paper, we argue that the single granularity is insufficient and leads to imprecise analysis.  ...  In the papers [27, 28] that serve as a foundation of this work, the program dependencies were not specified; it was only assumed that these dependencies can be extracted and they propagate the change  ...

Applying aggressive propagation-based strategies for testing changes

Raul Santelices, Mary Jean Harrold
