Dave's Unit Test (DUT) is a simple infrastructure for doing unit testing in C and C++. It can test boolean assertions, and test for the existence of expected C++ exceptions or POSIX signals. It also traps unexpected exceptions or signals.
DebugTrace is a tool for printing execution traces that are helpful for debugging. It shows every instruction as it is executed, the values of registers that are written, and the memory that is read and written.
DieHard automatically hardens software applications against a wide range of bugs. These bugs (known as memory errors) often end up as serious security vulnerabilities, cause crashes, or lead to unpredictable behavior.
DStress is a D programming language conformance test suite. It is used to test the DMD and GDC compilers.
Extended Python Debugger
Extended Python Debugger is a (slightly) more complete debugger for Python than the stock pdb.py debugger. It supports a "restart" command and stack traces that show fewer ?'s and give better information for exec statements.
Flawless is a simple Python framework developed at shopkick for detecting bugs in a production environment. Flawless traps exceptions and then uses git blame to send an email to the developer who wrote the buggy code.
Hat is a source-level tracer for Haskell 98, the standard lazy functional programming language. Hat is a tool that gives the user access to otherwise invisible information about a computation. Hat is portable between compilers: it works with both ghc and nhc98. It also supports various language extensions, such as the FFI, multi-parameter type classes, functional dependencies, and hierarchical module namespaces.
IPv6 CARE, the "IPv6 Compliance Automatic Runtime Experiment", is a tool for diagnosing the IPv6 compliance of programs while they are running.
Jockey is a user-space library for recording and replaying an execution of generic GNU/Linux programs. It is a debugging tool especially for long-running networked servers that suffer from bugs that are difficult to reproduce.
Kaputt is a testing tool for the Objective Caml language. It features both assertion-based tests (like in the xUnit framworks) and specification-based tests (like in the QuickCheck tool).
latrace is a glibc 2.4+ LD_AUDIT frontend. It allows you to trace library calls and get their statistics in a manner similar to the strace utility.

minibug is a simple two-window debugger for assembler programs. It runs in the console or X terminal. It reads ELF executables and extracts any symbols or comment information. Registers, breakpoints, memory, and disassembly are displayed.
nwsystest is a simple tool to help test full software systems - potentially consisting of multiple concurrent applications and threads - in an automated manner.
phook is a userspace tool that injects code into any application at run-time using ptrace(). It has a modular design to allow one use different plugins to make the target application do whatever is wanted.
PScan is a limited problem scanner for C source files.
PyChecker is a static analysis tool for finding bugs in Python source code. It finds problems that are typically caught by a compiler for less dynamic languages, like C and C++. It is similar to lint.
PyCrash is a Run-Time Exception Dumper which handles uncaught exceptions during the execution of Python programs and collects information about the program context. PyCrash can be very useful in report bug information, because the programmer can easily analyse the program execution context of the crashed application.
Pydb is a modified version of the standard Python debugger, pdb, with a number of augmented features that make it suitable for use with DDD, the Data Display Debugger.
Pyflakes is a simple program which checks Python source files for errors. It is similar to PyChecker in scope, but differs in that it does not execute the modules to check them. This is both safer and faster, although it does not perform as many checks. Unlike PyLint, Pyflakes checks only for logical errors in programs; it does not perform any checks on style.
PyreRing is a test runner that executes scripts intended to act as individual test cases. By removing the administrative burden that often surrounds testing, the test author can focus on writing meaningful, direct, and useful test cases. As long as you wrap your test cases with a Unix shell or scripted language wrapper, it will be executed. It allows you to set a timeout value, send reports to email addresses, automatically organize your test cases with filesystem directories or suite files that you define, create automatic suites based on a predefined block in your test scripts, and capture standard out and standard error into a comprehensive log.
This is a small package that facilitates the unit testing process by aggregating PyUnit tests and making them easier to call from the command line and from within other unit tests.
python-ptrace is a debugger using ptrace written in Python. It's able to control multiple processes, read/write bytes, perform breakpoint and step by step execution, use a disassembler, syscall tracer, and parser, explain why a signal is raised, dump registers, stack, and memory mappings, etc.
RCUNIT stands for Robust C Unit. It is a small framework for testing C programs. Similar to other unit testing frameworks, RCUNIT is a framework used for creating repeatable tests. RCUNIT provides uniform interfaces for managing tests. It provides optional setup and tear down functions both for tests and test suites, multiple test registries and test suites, test run and assertion failure callbacks, and an output redirection mechanism for log and test run reports. Requiring only an ANSI compliant C compiler, RCUNIT is a highly portable unit testing tool.
A GObject reference count debugger. GObject is part of the glib library (not to be confused with glibc) which forms the basis of GTK+ (the Gimp ToolKit), Gnome, GStreamer and many other projects. The GObject library adds object oriented stuff to C which by itself lacks object oriented features. Refdbg aims to ease the task of finding GObject reference count bugs which can lead to memory leaks or program crashes.
scanmem is a simple interactive debugging utility used to locate the address of a variable in an executing process. This can be used for the analysis or modification of a hostile process, or as a "pokefinder", used to cheat at video games.
shUnit2 is a unit testing framework for shell scripts (eg. sh, bash) that is modeled after the JUnit framework. It is designed to make unit testing in shell as simple as possible.
Smatch is a way of finding errors in source code, especially the Linux kernel source and potentially it may be useful for other people too someday.
