TTEST is a toolbox for the handling and automated testing of scientific software written in GNU Octave and Matlab that has been developed with applications in acoustic research in mind. Besides providing numeric comparison tests at various degrees of severity and precision, including support for floating point numbers, TTEST provides string comparison tests, and tests for comparing properties such as the output dimensions of the system under test.While the usage of TTEST requires no advanced programming knowledge, it targets specifically the testing of complex functions like audio signal processing algorithms and auditory models by providing gold standard and property based tests. Moreover, the toolbox comes with functions to trace and verify the code's control flow and can thus help saving time and effortin understanding and managing pre-existing code.TTEST is fast, requires little excess code, and allows for embedding the tests as comments within the code. It is hoped to be useful even for the implementation of small projects.
