Create numerics library (LIBBN) unit test for qmath.c

completed by: Andromeda Galaxy

mentors: Hardeep Singh Rai, Gauravjeet Singh

There are more than 300 library functions in our core LIBBN library. As a core library used by nearly every one of BRL-CAD's tools, testing those functions for correct behavior is important.


  • include/bn.h
  • include/plot3.h
  • include/vmath.h
  • src/libbn/qmath.c
  • src/libbu/tests/*.c (note libbu, not libbn for examples)
  • src/libbn/tests/*.c


  • src/libbn/tests/qmath.c
  • src/libbn/tests/CMakeLists.txt

This task involves implementing a new unit test for any of LIBBN's source files that do not already have a unit test defined. The test should run all of the public functions and be hooked into our build system. We have lots of existing unit tests to follow as an example.
