Constructing a Reproducible Testing Environment for Distributed Java Applications

Executions with internal nondeterministic choices makethe testing procedure non-repeatable. A natural solution isto artificially enforce and direct the execution to take the desiredpath so that a test can be reproduced. With geographicallydistributed processes and heterogenous platform architectures,distributed systems have raised new dimensionsof challenges to develop effective techniques for the reproducibletesting. In this paper, we discuss the architecturaland design issues on constructing an environment to automatesuch a testing for distributed Java applications. Ourfocus is on controlling the order of input and remote callevents in the application under test during the test procedure.The testing environment is by itself distributed anddoes not require code intrusion.
