Likwid is a set of easy to use command line tools for Linux. It supports programmers in developing high performance multi-threaded programs. "Likwid" stands for "Like I knew what I am doing". It contains the following tools: likwid-topology, which shows thread and cache topology; likwid-perfctr, which measures hardware performance counters on Intel and AMD processors; likwid-features, which shows and toggles hardware prefetch control bits on Intel Core 2 processors; likwid-pin, which pins a threaded application without touching its code (it supports pthreads, Intel OpenMP, and gcc OpenMP), likwid-powermeter which prints the Turbo mode steps and measures energy consumption on supported Intel processors, and likwid-bench, a low level benchmarking framework. It works with any standard Linux kernel. Likwid is lightweight and adds no overhead during measurements.
StoryText (formerly PyUseCase) is an unconventional GUI testing tool written in Python. It currently has mature support for PyGTK, beta status support for Java Swing, SWT/Eclipse RCP, and Tkinter, and very basic support for wxPython. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates it into the current GUI layout. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it, so as to use that as a baseline for text-based testing, using e.g. TextTest. Instead of requiring the tester to add "wait" statements by hand, it includes support for instrumenting code so that "waits" can be recorded.
crpcut is the Compartmented Robust Posix C++ Unit Test system. crpcut (pronounced "Crap Cut") runs all test cases in their own process and their own working directory, which makes it perfectly normal to test that asserts do trap, and the test suite continues even in the event of an unexpected SIGSEGV. By using the C++11 features long available in GCC, the tests are extremely easy to write.
SWEC is a program that automates testing of dynamic Web sites. It parses each HTML file it finds for links, and if those links are within the site specified, it will check that page as well. In addition to parsing and locating links, it will also parse the pages looking for known errors and report those. It will report if a page cannot be read (by either returning a 404, 500, or similar).
MIN is an advanced unit/integration test framework for Maemo/Linux. It supports test cases written in C (or C++) as well as scripted test cases with (a tailor made) MIN scripter, Lua, or Python. Test cases are compiled into test modules that are loaded dynamically. A test case is executed in a separate process.
Scalasca is a toolset that can be used to analyze the performance behavior of parallel applications and to identify opportunities for optimization. It supports an incremental performance-analysis procedure that integrates runtime summaries with in-depth studies of concurrent behavior via event tracing, adopting a strategy of successively refined measurement configurations.
mutest is a micro unit testing framework for C (with some C++ support). It is easy to use and has no dependencies. The idea is simple: a source file is a test suite, and a function is a test case (special functions can be used for test suite initialization and termination) that can can have several checks. Checks comes in 2 flavors: one that only prints an error, and one that terminates the current test case too. A (normally) automated test program run all the test suites and prints some stats. It fails (returns non-zero) if any test suite fails.
