# 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 full test suite
|
|
|
|
[pipenv] is a tool for making reproducible Python environments. Install it with:
|
|
```sh
|
|
sudo pip3 install pipenv
|
|
```
|
|
In the `trezor-firmware` checkout, install the environment:
|
|
```sh
|
|
pipenv sync
|
|
```
|
|
And run the automated tests:
|
|
```sh
|
|
pipenv run make -C core test_emu
|
|
```
|
|
|
|
|
|
### 2. Running tests manually
|
|
|
|
Install the pipenv environment as outlined above. Then switch to a shell inside the
|
|
environment:
|
|
|
|
```sh
|
|
pipenv shell
|
|
```
|
|
|
|
If you want to test against the emulator, run it in a separate terminal from the `core`
|
|
subdirectory:
|
|
```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 with `pytest`, either from `python` or `core` 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 [device_tests] directory. 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. Using markers
|
|
|
|
When you're developing a new currency, you should mark all tests that belong to that
|
|
currency. For example, if your currency is called NewCoin, your device tests should have
|
|
the following marker:
|
|
|
|
```python
|
|
@pytest.mark.newcoin
|
|
```
|
|
|
|
This marker must be registered in [REGISTERED_MARKERS] file.
|
|
|
|
If you wish to run a test only on TT, mark it with `@pytest.mark.skip_t1`.
|
|
If the test should only run on T1, mark it with `@pytest.mark.skip_t2`.
|
|
You must not use both on the same test.
