Your application has finally been tested and deployed in a production environment. However, the IT operators are complaining that the application is consuming more system resources than originally expected. The problem being described by the IT operators cannot be repeated in the development environment. To establish the cause of these problems, it's important to get enough information about the runtime environment, more specifically what is going on inside the Java Virtual Machine (JVM). Before J2SE 5.0, the information available from the JVM was at best extremely limited. JSR 174 has added management and monitoring APIs in J2SE 5.0 that expose valuable JVM information. The exposed information ranges from JVM health indicators like memory and threads to class loading and garbage collection information. This article provides an introduction to manageability and des... (more)

Graphical user interface (GUI) testing is a potentially problematic area because constructing effective test cases is more difficult than the corresponding application logic. The roadblocks to effective functional GUI testing are: Traditional test coverage criteria like "80% coverage of the lines of code" may not be sufficient to trap all the user interaction scenarios. End users often use a different user task interaction model than the one conceived by the development team. Functional GUI testing needs to deal with GUI events as well as the effects of the underlying applicati... (more)
