A comprehensive guide to testing smart contracts on Stellar using Soroban, covering unit tests, integration tests, fork tests, fuzzing, differential testing, and code coverage strategies all built into the Rust SDK.
This definitive guide explains why testing is critical for smart contract development and details Stellar's comprehensive testing ecosystem. It covers multiple testing strategies including unit tests for isolated functionality, integration tests spanning multiple components, fork tests using Mainnet data snapshots, fuzzing for identifying unexpected behavior, differential tests for comparing contract versions, and mutation testing for code coverage. All testing is performed using the real Soroban runtime rather than emulators, with a unified Rust toolchain and IDE support. The guide emphasizes that Stellar's testing infrastructure is seamlessly integrated into the Soroban SDK from the start, enabling developers to write tests early and confidently.
