DyMMEr: uma ferramenta para avaliação de qualidade do modelo de linhas de produtos de software dinâmicas

Abstract

Software Product Lines (SPL) is an approach that has as its central point the systematic reuse of software artifacts based on a family of products designed from the outset for the purpose of reuse. However, the SPLs represent the variability of products generated only in a static way, ie adaptation occurs only at design time, requiring different configurations are generated as needed by the customer and its execution environment. Then come the Dynamic Software Product Lines (DSPL), allowing the development of software capable of adapting to different requirements and restrictions on the current changes in the environment. It is important to ensure the quality of artifacts and software products to be supplied by the SPLs and DSPLs. A more viable approach to ensure the quality of SPL would evaluate quality in the early stages of development of SPL, thereby preventing errors from propagating to other stages of development and consequently the final products. Apply quality measures in artifacts can prevent errors are passed to later stages of development. This work aims to develop a tool to assess the quality of the feature model in order to include other measures such as new features of the system to evaluate quality attributes of feature models of SPLs and DSPLs. It were also defined in the tool features for editing the feature models for inserting context of adjustments and including context of adaptation rules for activation and deactivation features. For evaluation tool was used thirty feature models, applying all measures and exporting its results, as implemented in the tool functionality, to be analyzed by Epi Info® software.
