摘要： J-Orchestra is a system that enhances centralized Java programs with distribution capabilities. Operating at the bytecode level, J-Orchestra transforms a centralized Java program (i.e., running on a single Java Virtual Machine (JVM)) into a distributed one (i.e., running across multiple JVMs). This transformation effectively separates distribution concerns from the core functionality of a program. J-Orchestra follows a semiautomatic transformation process. Through a GUI, the user selects program elements (at class granularity) and assigns them to network locations. Based on the user's input, the J-Orchestra backend automatically partitions the program through compiler-level techniques, without changes to the JVM or to the Java Runtime Environment (JRE) classes. By means of bytecode engineering and code generation, J-Orchestra substitutes method calls with remote method calls, direct object references with proxy references, etc. It also translates Java language features (e.g., static methods and fields, inheritance, inner classes, new object construction, etc.) for efficient distributed execution. We detail the main technical issues that J-Orchestra addresses, including its mechanism for program transformation in the presence of unmodifiable code (e.g., in JRE classes) and the translation of concurrency and synchronization constructs to work correctly over the network. We further discuss a case study of transforming a large, commercial, third-party application for efficient execution in a client server environment and outline the architectural characteristics of centralized programs that are amenable to automated distribution with J-Orchestra.

摘要： Test case generation based on design specifications is an important part of testing processes. In this paper, Unified Modeling Language activity diagrams are used as design specifications. By setting up several test adequacy criteria with respect to activity diagrams, an automatic approach is presented to generate test cases for Java programs. Instead of directly deriving test cases from activity diagrams, this approach selects test cases from a set of randomly generated ones according to a given test adequacy criterion. In the approach, we first instrument a Java program under testing according to its activity diagram model, and randomly generate abundant test cases for the program. Then, by running the instrumented program we obtain the corresponding program execution traces. Finally, by matching these traces with the behavior of the activity diagram, a reduced set of test cases are selected according to the given test adequacy criterion. This approach can also be used to check the consistency between the program execution traces and the behavior of activity diagrams.
