OpenMesh comes with a set of unittests for all platforms.

In order to run these tests, you need to enable the cmake flag OPENMESH_BUILD_UNIT_TESTS. You also need GoogleTest on your machine. Configure the cmake variables in OpenMesh to point to your GTest include dirs and libraries (check the Advanced button in cmake, if you don't see these options). Than run cmake and build OpenMesh.

Afterwards you should have a Unittests subdirectory in your binary build folder. This directory includes the unittest executables and several test files for input and output checks. You can run the executables directly, but make sure, that the working directory is the directory where the executables are.
