pftp allows you to send and receive files and directories recursively, send and receive standard input and ouput, filter your connection, set the net buffer size, set the bandwidth, send UDP datagrams unicasted, broadcasted, and multicasted (which is meant for AUDIO and VIDEO streaming), send data to another user and manage that data, perform a network test based on either UDP or TCP, and use optimized buffers for your Gigabit Ethernet links. pftp can start from command line, as a daemon, or by inetd. All features are supported for IPv4 and IPv6.
OpenLoad is a tool for load-testing Web applications. It aims to be easy to use and providing near real-time performance measurements of the application under test. This is particulary useful when you are doing optimization as you can see the impact of your changes almost immediately.
Java Memory Profiler (JMP) uses the JVMPI interface to track objects and method times in the JVM (Java Virtual Machine). It uses a GTK+ interface to display statistics. The current instance count and the total amount of memory for each class is shown as is the total time spent in each method.
QtUnit is a unit testing framework for C++ which compiles into a shared library. It uses the Qt library for platform independence. Tests can be compiled into modules which are automatically reloaded after modification. The text and graphical testrunners are fully localized and integrate perfectly into IDEs for the display of the exact source location where failures occurred.
Do178Builder is a documentation tool used throughout the software/hardware development effort, helping to produce the DO-178B/254 documentation much less painfully. A major obstacle to creating airborne products, for smaller developers, is the necessity to qualify the software per RTCA/DO-178B, or hardware per RTCA/DO-254. Without this qualification, airborne products cannot be deployed.
sipsak is a command line tool for performing various tests on Session Initiation Protocol (SIP) applications and devices. It can make several different tests, send the contents of a file, and interpret and react on the responses. It supports (de-) registration with given contact URIs and digest authentication.
Xerver is a fast, tiny Web server which allows you to run CGI scripts (Perl, PHP, etc.), create aliases (virtual directories), allow/deny directory listings, create your own error pages ("404 Not Found"), allow/deny CGI scripts, password protect folders, choose your own index file extensions, share/unshare hidden files or files with certain file extensions, share unlimited folders, etc. It supports HTTP/0.9, HTTP/1.0, HTTP/1.1, and all HTTP methods (GET, POST and HEAD).
Kodos is a regular expression designer, tester, debugger, and validator that allows a developer to create and modify regular expressions against a test string. The intuitive interface allows the developer the ability to modify the regular expression (regex) and to see the effects against their test string in real-time.
