We present the concepts, usage and prototypical implementation of aPET, a test case generation tool for a distributed asynchronous language based on concurrent objects. The system receives as input a program, a selection of methods to be tested, and a set of parameters that include a selection of a coverage criterion. It yields as output a set of test cases which guarantee that the selected coverage criterion is achieved. aPET is completely integrated within the language's IDE via Eclipse. The generated test cases can be displayed in textual mode and, besides, it is possible to generate ABSUnit code (i.e., code runnable in a simple framework similar to JUnit to write repeatable tests). The information yield by aPET can be relevant to spot bugs during program development and also to perform regression testing.

FMSPLE 2012 is the third edition of the FMSPLE workshop series, traditionally affiliated with SPLC, which aims to connect researchers and practitioners interested in raising the efficiency and the effectiveness of SPLE through the application of innovative analysis approaches and formal methods.

This workshop will bring together researchers interested in raising the efficiency and the effectiveness of Software Product Line Engineering by applying innovative analysis approaches and formal methods.
