Search-Based Crash Reproduction and Its Impact on Debugging

Software systems fail. These failures are often reported to issue tracking systems, where they are prioritized and assigned to responsible developers to be investigated. When developers debug software, they need to reproduce the reported failure in order to verify whether their fix actually prevents the failure from happening again. Since...

Refactoring Fat Interfaces Using a Genetic Algorithm

Recent studies have shown that the violation of the Interface Segregation Principle (ISP) is critical for maintaining and evolving software systems. Fat interfaces (i.e., interfaces violating the ISP) change more frequently and degrade the quality of the components coupled to them. According to the ISP the interfaces’ design should force no...

A Genetic Algorithm to Find the Adequate Granularity for Service Interfaces

The relevance of the service interfaces’ granularity and its architectural impact have been widely investigated in literature. Existing studies show that the granularity of a service interface, in terms of exposed operations, should reflect their clients’ usage. This idea has been formalized in the Consumer-Driven Contracts pattern (CDC)....
