Checking Java implementation of a naming architecture using Testera

TestEra is a novel framework for automated testing of Java programs. We have built TestEra upon Alloy, a lightweight first-order relational language, and the Alloy Analyzer, a fully automatic simulation and checking tool. Checking a Java program with TestEra involves modeling the correctness criteria for the program in Alloy and specifying abstraction and concretization translations between instances of Alloy models and Java data structures. TestEra automatically generates all nonisomorphic test cases within a given input size and verifies the correctness. We present our initial evaluation of TestEra performed by checking the Java implementation of a naming architecture for resource discovery in dynamic networked environments. Our study delineates the use of TestEra in testing methods for manipulating complex data structures.
