# Running UI 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 tests:
|
|
|
|
```sh
|
|
poetry run make -C core test_emu_ui
|
|
```
|
|
|
|
## 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 with disabled animation in a separate terminal:
|
|
```sh
|
|
./core/emu.py -a
|
|
```
|
|
|
|
Now you can run the test suite with `pytest` from the root directory:
|
|
```sh
|
|
pytest tests/device_tests --ui=test
|
|
```
|
|
|
|
If you wish to check that all test cases in `fixtures.json` were used set the `--ui-check-missing` flag. Of course this is meaningful only if you run the tests on the whole `device_tests` folder.
|
|
|
|
```sh
|
|
pytest tests/device_tests --ui=test --ui-check-missing
|
|
```
|
|
|
|
# Updating Fixtures ("Recording")
|
|
|
|
Short version:
|
|
```sh
|
|
poetry run make -C core test_emu_ui_record
|
|
```
|
|
|
|
Long version:
|
|
|
|
The `--ui` pytest argument has two options:
|
|
|
|
- **record**: Create screenshots and calculate theirs hash for each test.
|
|
The screenshots are gitignored, but the hash is included in git.
|
|
- **test**: Create screenshots, calculate theirs hash and test the hash against
|
|
the one stored in git.
|
|
|
|
If you want to make a change in the UI you simply run `--ui=record`. An easy way
|
|
to proceed is to run `--ui=test` at first, see what tests fail (see the Reports section below),
|
|
decide if those changes are the ones you expected and then finally run the `--ui=record`
|
|
and commit the new hashes.
|
|
|
|
Also here we provide an option to check the `fixtures.json` file. Use `--ui-check-missing` flag again to make sure there are no extra fixtures in the file:
|
|
|
|
```sh
|
|
pytest tests/device_tests --ui=record --ui-check-missing
|
|
```
|
|
|
|
## Reports
|
|
|
|
### Tests
|
|
|
|
Each `--ui=test` creates a clear report which tests passed and which failed.
|
|
The index file is stored in `tests/ui_tests/reports/test/index.html`.
|
|
The script `tests/show_results.py` starts a local HTTP server that serves this page --
|
|
this is necessary for access to browser local storage, which enables a simple reviewer
|
|
UI.
|
|
|
|
On CI this report is published as an artifact. You can see the latest `main` branch report [here](https://gitlab.com/satoshilabs/trezor/trezor-firmware/-/jobs/artifacts/main/file/test_ui_report/index.html?job=core%20device%20test). The reviewer features work directly here.
|
|
|
|
If needed, you can use `python3 -m tests.ui_tests` to regenerate the report from local
|
|
recorded screens.
|
|
|
|
### Master diff
|
|
|
|
In the ui tests folder you will also find a Python script `report_master_diff.py`, which
|
|
creates a report where you find which tests were altered, added, or removed relative to
|
|
master. This useful for Pull Requests.
|
|
|
|
This report is available as an artifact on CI as well. You can find it by
|
|
visiting the "unix ui changes" job in your pipeline - browse the
|
|
artifacts and open `master_diff/index.html`.
