Testar is a tool that reduces testing time for large Java unit test suites. It runs on top of JUnit and automatically selects individual tests to execute based on changes made to the code since the previous tool invocation. It can be used both from the command line and inside an IDE.
jGetFile is a scriptable commandline recursive file downloader for the Web. It handles many of the HREF configurations not supported in other mass downloaders, such as embedded URLs in parameters. It also supports a highly configurable means to filter the acceptance of links within the program.
Simple Log is a small library that does logging very simply and requires you to do almost nothing (other than actually logging) to get log output to happen. It is much simpler to use than a logging framework, especially in terms of configuration. It doesn't attempt to solve every logging problem in one package, but contains enough features to be a viable alternative for most applications that need logging. This tool will handle the logging needs of most small- to large-sized projects, but with an almost non-existent learning curve.
