Running Tests

Setup

General configuration for pytest is under ledger-app/tests/functional/conftest.py. Configuration includes useful information like the app name, the devices, and the ragger backends.

Ragger

First install ragger. It is a python package.

pip install ragger

See Ragger Documentation for additional information.

Build The App

Follow the instructions in Readme.

Run The Emulator

To validate, run the app via speculos. Make sure that you run your emulator to match the build.

cd ledger-app
speculos build/nanosp/bin/app.elf

Testing

Install Packages

You will need to install several python packages

cd tests/functional
pip install -r requirements.txt

Run Tests

You can run emulated tests for a specific device or for all devices. Set --device to all for all devices. Use --display to see the emulated UI as the tests are run. The default mode runs the emulator in headless mode.

cd test/functional
pytest -v --tb=short --device=nanox --display

CleanUp

remove the directory ledger-app/tests/functional/snapshots-tmp/ to clean out the old snapshots
