Framework for testing Java concurrency

Concurrent programming has become ubiquitous in the arena of application development, requiring most production quality systems to deal with at least some degree of multi-threaded execution. An increasing level of maturity is developing around the impact of concurrency on the design and testing processes. Much of this knowledge focuses on the functional aspect of the design and execution with success measures typically related to the correctness of a program. However, there exists a gap in the research to date around the process for concurrent performance testing. While many companies acknowledge that performance is a major source of complaints in production environments, performance testing historically receives low priority and is often little more than an extension of the functional testing. Possibly the most widely discussed and understood implementation language today, in terms of multi-threaded programming, is Java. The report outlines a standard framework for concurrent performance testing targeted towards Java based applications. In an effort to vet the framework, we execute a series of practical concurrent testing that address some of the most common aspects of concurrent programming in Java, with a particular focus on the Java Concurrency package. As a result, this report presents a portable, extensible framework that designers can use in evaluating the range of concurrency options available in Java within their particular environment. Additionally, it provides specific insight into the performance of these options in a typical run-time environment. This includes particular attention to the comparison of traditional lock based approach to non-blocking algorithms. / text
