Starknet Foundry, like its Ethereum counterpart, consists of different modules

• Forge: Starknet testing framework (like Truffle, Hardhat and DappTools but for Starknet).
• Cast: All-in-one tool for interacting with Starknet smart contracts, sending transactions and getting chain data.

To install Starknet Foundry, run:

curl -L https://raw.githubusercontent.com/foundry-rs/starknet-foundry/master/scripts/install.sh | sh

You can also specify a version you wish to install:

curl -L https://raw.githubusercontent.com/foundry-rs/starknet-foundry/master/scripts/install.sh | sh -s -- -v 0.3.0

To verify that the Starknet Foundry is installed correctly, run snforge --version and sncast --version.

• Fast testing framework Forge written in Rust
• High-quality dependency management using scarb
• Intuitive interactions and deployment of Starknet contracts through Cast

Starknet Foundry is under active development! Expect a lot of new features to appear soon! 🔥

• Running tests written in Cairo
• Contract interactions testing
• Interacting with Starknet from command line
• Multicall support
• Cheatcodes
• Parallel tests execution
• Performance improvements
• Deployment scripts written in Cairo
• Starknet state forking
• Advanced debugging utilities
• L1 ↔ L2 messaging and cross-chain testing
• Transactions profiling
• Fuzz testing
• Test coverage reports

Forge achieves performance comparable to the Cairo Test Runner with improved user experience. All that is possible on just a single thread and multithreading is well on its way!
