Brownie is a Python-based development and testing framework for Ethereum smart contracts targeting the EVM, supporting Solidity and Vyper. It provides pytest-based contract testing, property-based testing via Hypothesis, debugging tools, and an interactive console, though it is no longer actively maintained in favor of Ape Framework.

Use cases

• test ethereum smart contracts in python
• deploy and interact with solidity contracts from python
• write property-based tests for smart contracts
• debug solidity contract transactions with tracebacks
• measure test coverage of vyper contracts
• run an interactive console against a local blockchain

When to choose

• you need a mature python framework for solidity or vyper contract testing
• you want pytest integration and trace-based coverage for ethereum projects
• you prefer hypothesis-based stateful testing for contracts

When to avoid

• you are starting a new project - the maintainers recommend Ape Framework instead
• you rely on ganache, which has been sunsetted
• you need actively maintained tooling with regular releases
