AQtime is an integrated performance and memory/resource optimization toolset aimed at applications running on the Linux platform. It can be used to discover application bottlenecks, memory leaks, resource-hogging code, or untested algorithms in any software projects. It then informs you which module, class, routine or line of code is causing the problem, and lets you quickly fix it. It can profile any executable that has the Executable and Linking Format (ELF) and the stabs format of the debug information.
guitest is a collection of helpers for unit-testing GUI applications written in Python. Support for pyGTK is most mature, and support for other toolkits is in progress. The library allows testing of modal dialogs and recursive main loop invocations while preventing the windows from being shown during test runs. Arbitrary classes and methods can be overridden, or call loggers attached to them.
