Testing scripts to test ulogs for px4-specific implementations.

To prevent any conflict with the system python version, it is suggested to use a virtual enrionment with python version 3.6 and higher. Otherwise, python 3.6 and higher must be the python system version. If you don't have 3.6 installed on your machinge, you can follow this tutorial.

First install virtualenv:

sudo apt install virtualenv

Install virtualenvrapper: this will install virtualenvwrapper.sh in ~/.local/bin

pip install virtualenvwrapper

Create a virtual environement directory

mkdir ~/.virtualenvs

Add virtual envrionment working-folder to bashrc and source virtualenvwrapper:

export WORKON_HOME=$HOME/.virtualenvs
source $HOME/.local/bin/virtualenvwrapper.sh

Open new terminal or source bashrc:

source ~/.bashrc

Create a virtual environment with python version 3 and no site packages included (python3 must be installed)

mkvirtualenv --python=python3 --no-site-packages [name-of-new-env]

You now created a new virtual environment with name [name-of-new-env].

To enter [name-of-new-env]:

workon [name-of-new-env]

To exit [name-of-new-env]:

deactivate

To test a log file, pass its absolute path as a command line argument (see example below)

All the tests are in the tests directory. Tests should be split into tests that apply for any ulog file and tests that are coupled to a specific simulated test.

To run general tests:

py.test -s tests/test_general.py --filepath=absolute/path/to/logfile.ulg

Using -s allows you to see print statements for the skipped tests

With the current default log, the test for tilt will fail because the vehicle flipped during the actual flight.
