# Testing

## Testing with python-trezor
|
|
|
|
Apart from the internal tests, Trezor core has a suite of integration tests in the [`python-trezor`](https://github.com/trezor/python-trezor) library. There are several ways to use that.
|
|
|
|
### 1. Running the suite with pipenv
|
|
|
|
[`pipenv`](https://docs.pipenv.org/) is a tool for making reproducible Python environments. Install it with:
|
|
|
|
```sh
|
|
sudo pip3 install pipenv
|
|
```
|
|
|
|
Inside `trezor-core` checkout, install the environment:
|
|
|
|
```sh
|
|
pipenv install
|
|
```
|
|
|
|
And run the automated tests:
|
|
|
|
```sh
|
|
pipenv run make test_emu
|
|
```
|
|
|
|
### 2. Developing new tests
|
|
|
|
You will need a separate checkout of `python-trezor`. It's probably a good idea to do this outside the `trezor-core` directory:
|
|
|
|
```sh
|
|
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`:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
python setup.py develop
|
|
```
|
|
|
|
If you want to test against the emulator, run it in a separate terminal from the `trezor-core` checkout directory:
|
|
|
|
```sh
|
|
PYOPT=0 ./emu.sh
|
|
```
|
|
|
|
Find the device address and export it as an environment variable. For the emulator, this is:
|
|
|
|
```sh
|
|
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:
|
|
|
|
```sh
|
|
pytest
|
|
```
|
|
|
|
Or from anywhere else:
|
|
|
|
```sh
|
|
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>`:
|
|
|
|
```sh
|
|
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`.
|
|
|
|
### 3. Submitting tests for new features
|
|
|
|
When you're happy with your tests, follow these steps:
|
|
|
|
1. Mark each of your tests with the name of your feature. E.g., `@pytest.mark.ultracoin2000`.
|
|
2. 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, run `pytest --runxfail`
|
|
3. Submit a PR to `python-trezor`, containing these tests.
|
|
4. Edit the file `trezor-core/pytest.ini`, and add your marker to the `run_xfail` item:
|
|
|
|
``` ini
|
|
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.
|
|
|
|
5. Submit a PR to `trezor-core`.
|
|
6. Optionally, if you like to be extra nice: after both your PRs are accepted, submit a new one to `python-trezor` that removes the `xfail` markers, and one to `trezor-core` that removes the `run_xfail` entry.
