 Testing
 =======
 
-To test python-OBD, you will need to `pip install pytest` and install the module (preferably in a virtualenv) by running `python setup.py install`. The end-to-end tests will also require [obdsim](http://icculus.org/obdgpslogger/obdsim.html) to be running in the background. When starting obdsim, note the "SimPort name" that it creates, and pass it as an argument to py.test.
+To test python-OBD, you will need to install `pytest` and the `obd` module from your local tree (preferably in a virtualenv) by running:
 
-To run all tests, run the following command:
+```bash
+pip install pytest
+pip install build
+python -m build
+pip install ./dist/obd-0.7.2.tar.gz
+```
 
-	$ py.test --port=/dev/pts/<num>
+To run all basic python-only unit tests, run:
+
+```bash
+py.test
+```
+
+This directory also contains a set of end-to-end tests that require [obdsim](http://icculus.org/obdgpslogger/obdsim.html) 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:
+  ```bash
+  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:
+  ```bash
+  py.test --port=/dev/pts/<num>
+  ```
