To run the microbenchmarks

1. You need to have hpy.devel installed in your virtuanenv. The easiest way to do it is:

   $ cd /path/to/hpy
   $ python setup.py develop
   

2. Build the extension modules needed for the microbenchmarks

   $ cd microbench
   $ pip install cffi # needed to build _valgrind
   $ python setup.py build_ext --inplace
   

3. py.test -v

4. To run only cpy or hpy tests, use -m (to select markers):

   $ py.test -v -m hpy
   $ py.test -v -m cpy
