A Python framework for Ethereum smart contract deployment, testing and interaction.
Project description
Brownie
Brownie is a Python-based development and testing framework for smart contracts targeting the Ethereum Virtual Machine.
Features
- Full support for Solidity (
>=0.4.22
) and Vyper (0.1.0-b16
) - Contract testing via pytest, including trace-based coverage evaluation
- Powerful debugging tools, including python-style tracebacks and custom error strings
- Built-in console for quick project interaction
- Support for ethPM packages
Dependencies
- ganache-cli - tested with version 6.7.0
- pip
- python3 version 3.6 or greater, python3-dev
As Brownie relies on py-solc-x, you do not need solc installed locally but you must install all required solc dependencies.
Installation
You can install the latest release via pip
:
pip install eth-brownie
Or clone the repository and use setuptools
for the most up-to-date version:
python3 setup.py install
Quick Usage
To set up the default folder and file structure for Brownie use:
brownie init
Next, type brownie --help
for basic usage information.
Documentation
Brownie documentation is hosted at Read the Docs.
Testing
To run the tests, first install the developer dependencies:
pip install -r requirements-dev.txt
Then use tox
to run the complete suite against the full set of build targets, or pytest
to run tests against a specific version of Python. If you are using pytest
you must include the -p no:pytest-brownie
flag to prevent it from loading the Brownie plugin.
Using Docker
You can use a sandbox container provided in the docker-compose.yml file for testing inside a Docker environment.
This container provides everything you need to test using a Python 3.6 interpreter.
Start the test environment:
docker-compose up -d
To open a session to the container:
docker-compose exec sandbox bash
To run arbitrary commands, use the bash -c
prefix.
docker-compose exec sandbox bash -c ''
For example, to run the tests in brownie/tests/test_format_input.py
:
docker-compose exec sandbox bash -c 'python -m pytest tests/convert/test_format_input.py'
Contributing
Help is always appreciated! Feel free to open an issue if you find a problem, or a pull request if you've solved an issue.
Join the Brownie Gitter channel if you have any questions.
Pre-Commit Hooks
We use pre-commit hooks, primarily to ensure consistent formatting among contributors.
If you haven't already, install all dev dependencies in requirements-dev.txt
to enable pre-commit hooks.
Install pre-commit locally from the brownie root folder:
pre-commit install
Commiting will now automatically run the local pre-commit hooks.
If, for some reason, you need to force the commit without running the pre-commit hooks, you can manually disable the pre-commit.
git commit -m "commit message" --no-verify
