Testing

Testing with python-trezor

Apart from the internal tests, Trezor core has a suite of integration tests in the python subdirectory. There are several ways to use that.

1. Running the suite with pipenv

pipenv is a tool for making reproducible Python environments. Install it with:

sudo pip3 install pipenv

Inside trezor-core checkout, install the environment:

pipenv install

And run the automated tests:

pipenv run make test_emu

2. Developing new tests

Prepare a virtual environment with all the requirements, and switch into it. Again, it's easiest to do this with pipenv:

pipenv install
pipenv shell

Alternately, if you have an existing virtualenv, you can install python in "develop" mode:

python setup.py develop

If you want to test against the emulator, run it in a separate terminal from the core subdirectory:

PYOPT=0 ./emu.sh

Find the device address and export it as an environment variable. For the emulator, this is:

export TREZOR_PATH="udp:127.0.0.1:21324"

(You can find other devices with trezorctl list.)

Now you can run the test suite, either from python or core root directory:

pytest

Or from anywhere else:

pytest --pyargs trezorlib.tests.device_tests  # this works from other locations

You can place your own tests in trezorlib/tests/device_tests. See test style guide (TODO).

If you only want to run a particular test, pick it with -k <keyword> or -m <marker>:

pytest -k nem      # only runs tests that have "nem" in the name
pytest -m stellar  # only runs tests marked with @pytest.mark.stellar

If you want to see debugging information and protocol dumps, run with -v.
