Apart from the internal tests, Trezor core has a suite of integration tests in the python-trezor
library. There are several ways to use that.
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
You will need a separate checkout of python-trezor
. It's probably a good idea to do this outside the trezor-core
directory:
git clone https://github.com/trezor/python-trezor
Prepare a virtual environment with all the requirements, and switch into it. Again, it's easiest to do this with pipenv
:
cd python-trezor
pipenv install -r requirements-dev.txt
pipenv install -e .
pipenv shell
Alternately, if you have an existing virtualenv, you can install python-trezor in "develop" mode:
python setup.py develop
If you want to test against the emulator, run it in a separate terminal from the trezor-core
checkout directory:
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-trezor
or trezor-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
.
When you're happy with your tests, follow these steps:
-
Mark each of your tests with the name of your feature. E.g.,
@pytest.mark.ultracoin2000
. -
Also mark each of your tests with
@pytest.mark.xfail
. That means that the test is expected to fail. If you want to run that test as usual, runpytest --runxfail
-
Submit a PR to
python-trezor
, containing these tests. -
Edit the file
trezor-core/pytest.ini
, and add your marker to therun_xfail
item:run_xfail = lisk nem ultracoin2000
This will cause your PR to re-enable the
xfail
ed tests. That way we will see whether your feature actually implements what it claims. -
Submit a PR to
trezor-core
. -
Optionally, if you like to be extra nice: after both your PRs are accepted, submit a new one to
python-trezor
that removes thexfail
markers, and one totrezor-core
that removes therun_xfail
entry.
