## How to Contribute

### Configuring python environment

The project development requires Python version 3.9+. To set it as default in the environment run the following commands:

```sh
# You may need to install python 3.9 venv if it's missing, on Ubuntu just run `sudo apt-get install python3.9-venv`
python3.9 -m venv env
source ./env/bin/activate
```

Install required dependencies:

```sh
python -m pip install --upgrade pip
pip install -r local-requirements.txt
```

Build and install drivers:

```sh
pip install -e .
python -m build --wheel
```

Run tests:

```sh
pytest --browser chromium
```

Checking for typing errors

```sh
mypy playwright
```

Format the code

```sh
pre-commit install
pre-commit run --all-files
```

For more details look at the [CI configuration](./.github/workflows/ci.yml).

Collect coverage

```sh
pytest --browser chromium --cov-report html --cov=playwright
open htmlcov/index.html
```

### Regenerating APIs

```bash
./scripts/update_api.sh
pre-commit run --all-files
```
