In this article, we empirically study the suitability of tests as acceptance criteria for automated program fixes, by checking patches produced by automated repair tools using a bug-finding tool, as opposed to previous works that used tests or manual inspections. We develop a number of experiments in which faulty programs from IntroClass , a known...

Alloy is a formal specification language, which despite featuring a simple syntax and relational semantics, is very expressive and supports efficient automated specification analysis, based on SAT solving. While the language is sufficiently expressive to accommodate both static and dynamic properties of systems within specifications, the latter...

Various tools for program analysis, including run-time assertion checkers and static analyzers such as verification and test generation tools, require formal specifications of the programs being analyzed. Moreover, many of these tools and techniques require such specifications to be written in a particular style, or follow certain patterns, in orde...

We describe DynAlloy Analyzer, a tool that extends Alloy Analyzer with support for dynamic elements in Alloy models. The tool builds upon Alloy Analyzer in a way that makes it fully compatible with Alloy models, and extends their syntax with a particular idiom, inspired in dynamic logic, for the description of dynamic behaviours, understood as sequ...

Formal specifications in Alloy are organized around user-defined data domains, associated with signatures, with almost no support for built-in datatypes. This minimality in the built-in data types provided by the language is one of its main features, as it contributes to the automated analyzability of models. One of the few built-in datatypes avail...
