# Unit Tests
# Testing
These are good. We should have some one day.
We use a combination of Integration and Unit testing to ensure that the our code is as bug-free as possible. All the tests can be found in `lib/python/qmk/tests/`.
At the time of this writing our tests are not very comprehensive. Looking at the current tests and writing new test cases for untested situations is a great way to both familiarize yourself with the codebase and contribute to QMK.
## Integration Tests
Integration tests can be found in `lib/python/qmk/tests/test_cli_commands.py`. This is where CLI commands are actually run and their overall behavior is verified. We use [`subprocess`](https://docs.python.org/3.5/library/subprocess.html#module-subprocess) to launch each CLI command and a combination of checking output and returncode to determine if the right thing happened.
## Unit Tests
The other `test_*.py` files in `lib/python/qmk/tests/` contain unit tests. You can write tests for individual functions inside `lib/python/qmk/` here. Generally these files are named after the module, with dots replaced by underscores.
At the time of this writing we do not do any mocking for our tests. If you would like to help us change this please [open an issue](https://github.com/qmk/qmk_firmware/issues/new?assignees=&labels=cli%2C+python&template=other_issues.md&title=) or [join #cli on Discord](https://discord.gg/heQPAgy) and start a conversation there.
