Many distributions append suffixes to installed Python script names to differentiate between Python 2 and 3 versions. For example, Debian installs the Python 3 pytest binary as `py.test-3` (see https://packages.debian.org/stretch/all/python3-pytest/filelist). In the unit tests, invoke the pytest binary using `sys.exectuable` to make sure that the subprocesses run with the same version of Python as the unit tests themselves.
