Development

After cloning the project, you'll need to set up the development environment. Here are the guidelines on how to do this.

Virtual Environment with venv

Create a virtual environment in a directory using Python's venv module:

python -m venv venv

That will create a ./venv/ directory with Python binaries, allowing you to install packages in an isolated environment.

Activate the Environment

Activate the new environment with:

source ./venv/bin/activate

Ensure you have the latest pip version in your virtual environment:

python -m pip install --upgrade pip

Installing Dependencies

After activating the virtual environment as described above, run:

pip install -e ".[dev]"

This will install all the dependencies and your local project in your virtual environment.

Using Your local Project

If you create a Python file that imports and uses taskiq_faststream, and run it with the Python from your local environment, it will use your local taskiq_faststream source code.

Whenever you update your local taskiq_faststream source code, it will automatically use the latest version when you run your Python file again. This is because it is installed with -e.

This way, you don't have to "install" your local version to be able to test every change.

Running Tests

Pytest

To run tests with your current FastStream application and Python environment, use:

pytest tests
# or
./scripts/test.sh
# with coverage output
./scripts/test-cov.sh
