- python3 -sBm build -w --no-isolation
- because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
- install .whl file in </install/prefix> using installer module
- run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
- build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")
