To test python-OBD, you will need to install pytest and the obd module from your local tree (preferably in a virtualenv) by running:

pip install pytest
pip install build
python -m build
pip install ./dist/obd-0.7.2.tar.gz

To run all basic python-only unit tests, run:

py.test

This directory also contains a set of end-to-end tests that require obdsim to be running in the background. These tests are skipped by default, but can be activated by passing the --port flag.

• Download obdgpslogger: https://icculus.org/obdgpslogger/downloads/obdgpslogger-0.16.tar.gz
• Run the following build commands:

  mkdir build
  cd build
  cmake ..
  make obdsim

• Start ./bin/obdsim, note the SimPort name: /dev/pts/<num> that it creates. Pass this pseudoterminal path as an argument to py.test:

  py.test --port=/dev/pts/<num>
