# Running device tests
|
|
|
|
## 1. Running the full test suite
|
|
|
|
_Note: You need Poetry, as mentioned in the core's [documentation](https://docs.trezor.io/trezor-firmware/core/) section._
|
|
|
|
In the `trezor-firmware` checkout, in the root of the monorepo, install the environment:
|
|
|
|
```sh
|
|
poetry install
|
|
```
|
|
|
|
And run the automated tests:
|
|
|
|
```sh
|
|
poetry run make -C core test_emu
|
|
```
|
|
|
|
## 2. Running tests manually
|
|
|
|
Install the poetry environment as outlined above. Then switch to a shell inside the
|
|
environment:
|
|
|
|
```sh
|
|
poetry shell
|
|
```
|
|
|
|
If you want to test against the emulator, run it in a separate terminal:
|
|
```sh
|
|
./core/emu.py
|
|
```
|
|
|
|
Now you can run the test suite with `pytest` from the root directory:
|
|
```sh
|
|
pytest tests/device_tests
|
|
```
|
|
|
|
### Useful Tips
|
|
|
|
The tests are randomized using the [pytest-random-order] plugin. The random seed is printed in the header of the tests output, in case you need to run the tests in the same order.
|
|
|
|
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`.
|
|
|
|
If you would like to interact with the device (i.e. press the buttons yourself), just prefix pytest with `INTERACT=1`:
|
|
|
|
```sh
|
|
INTERACT=1 pytest tests/device_tests
|
|
```
|
|
|
|
## 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.

|
## Extended testing and debugging
|
|
|
|
### Building for debugging (Emulator only)
|
|
|
|
Build the debuggable unix binary so you can attach the gdb or lldb.
|
|
This removes optimizations and reduces address space randomizaiton.
|
|
|
|
```sh
|
|
make build_unix_debug
|
|
```
|
|
|
|
The final executable is significantly slower due to ASAN(Address Sanitizer) integration.
|
|
If you wan't to catch some memory errors use this.
|
|
|
|
```sh
|
|
time ASAN_OPTIONS=verbosity=1:detect_invalid_pointer_pairs=1:strict_init_order=true:strict_string_checks=true TREZOR_PROFILE="" poetry run make test_emu
|
|
```
|
|
|
|
### Coverage (Emulator only)
|
|
|
|
Get the Python code coverage report.
|
|
|
|
If you want to get HTML/console summary output you need to install the __coverage.py__ tool.
|
|
|
|
```sh
|
|
pip3 install coverage
|
|
```
|
|
|
|
Run the tests with coverage output.
|
|
|
|
```sh
|
|
make build_unix && make coverage
|
|
```
