# Brownie [](https://pypi.org/project/eth-brownie/) [](https://travis-ci.com/iamdefinitelyahuman/brownie) [](https://eth-brownie.readthedocs.io/en/latest/) [](https://coveralls.io/github/iamdefinitelyahuman/brownie?branch=master) Brownie is a Python-based development and testing framework for smart contracts targeting the [Ethereum Virtual Machine](https://solidity.readthedocs.io/en/v0.6.0/introduction-to-smart-contracts.html#the-ethereum-virtual-machine). ## Features * Full support for [Solidity](https://github.com/ethereum/solidity) (`>=0.4.22`) and [Vyper](https://github.com/vyperlang/vyper) (`0.1.0-b17`) * Contract testing via [`pytest`](https://github.com/pytest-dev/pytest), including trace-based coverage evaluation * Property-based and stateful testing via [`hypothesis`](https://github.com/HypothesisWorks/hypothesis/tree/master/hypothesis-python) * Powerful debugging tools, including python-style tracebacks and custom error strings * Built-in console for quick project interaction * Support for [ethPM](https://www.ethpm.com) packages ## Dependencies * [python3](https://www.python.org/downloads/release/python-368/) version 3.6 or greater, python3-dev * [ganache-cli](https://github.com/trufflesuite/ganache-cli) - tested with version [6.8.2](https://github.com/trufflesuite/ganache-cli/releases/tag/v6.8.2) Brownie uses [`py-solc-x`](https://github.com/iamdefinitelyahuman/py-solc-x) for solc version management. You do not need solc installed locally, but you must install all required [solc dependencies](https://solidity.readthedocs.io/en/latest/installing-solidity.html#binary-packages). ## Installation ### via `pipx` The recommended way to install Brownie is via [`pipx`](https://github.com/pipxproject/pipx). pipx installs Brownie into a virtual environment and makes it available directly from the commandline. Once installed, you will never have to activate a virtual environment prior to using Brownie. To install `pipx`: ```bash python3 -m pip install --user pipx python3 -m pipx ensurepath ``` To install Brownie using `pipx`: ```bash pipx install eth-brownie ``` To upgrade to the latest version: ```bash pipx upgrade eth-brownie ``` ### via `pip` You can install the latest release via [`pip`](https://pypi.org/project/pip/): ```bash pip install eth-brownie ``` ### via `setuptools` You can clone the repository and use [`setuptools`](https://github.com/pypa/setuptools) for the most up-to-date version: ```bash git clone https://github.com/iamdefinitelyahuman/brownie.git cd brownie python3 setup.py install ``` ## Quick Usage To initialize a new Brownie project, start by creating a new folder. From within that folder, type: ```bash brownie init ``` Next, type `brownie --help` for basic usage information. ## Documentation and Support Brownie documentation is hosted at [Read the Docs](https://eth-brownie.readthedocs.io/en/latest/). If you have any questions about how to use Brownie, feel free to ask on [Ethereum StackExchange](https://ethereum.stackexchange.com/) or join us on [Gitter](https://gitter.im/eth-brownie/community). ## Testing To run the tests, first install the developer dependencies: ```bash pip install -r requirements-dev.txt ``` Then use [`tox`](https://github.com/tox-dev/tox) to run the complete suite against the full set of build targets, or [`pytest`](https://github.com/pytest-dev/pytest) to run tests against a specific version of Python. If you are using [`pytest`](https://github.com/pytest-dev/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`](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: ```bash docker-compose up -d ``` To open a session to the container: ```bash docker-compose exec sandbox bash ``` To run arbitrary commands, use the `bash -c` prefix. ```bash docker-compose exec sandbox bash -c '' ``` For example, to run the tests in `brownie/tests/test_format_input.py`: ```bash docker-compose exec sandbox bash -c 'python -m pytest tests/convert/test_format_input.py' ``` ## Contributing Help is always appreciated!
