provenance-test-tube

provwasm-test-tube is a generic library for building testing environments for ProvWasm smart contracts. It allows you to test your smart contract logic against the actual Cosmos SDK chain's logic, which is written in Go, using Rust. This eliminates the need to write Go code or learn Go in order to test your smart contracts against Provenance Blockchain.

This provwasm-test-tube repository is a fork of osmosis-test-tube, customized for Provenance Blockchain.

Features

  • Test your ProvWasm smart contracts using Rust without the need to write Go code or learn Go
  • Test against the actual Provenance chain's logic

Usage

See the documentation

What about cw-multi-test?

You might want to just use cw-multi-test if your contract does not interact with Provenance's custom modules. cw-multi-test is faster since it does not need to run the chain code or build and upload .wasm file, but it does not test your contract against the actual chain's logic and rely on simulation which only some basic modules are implemented.

So if your contract just interact with common modules like Bank, Staking, and Distribution, cw-multi-test is enough. But if it's interacting with custom modules, you should use provwasm-test-tube.

Known Issues

linking with cc failed on Mac M1/M2 (arm64) osmosis-labs/test-tube#28

Check your go version if it's darwin/arm64, it might be darwin/amd64 and your local build has been working but it confuses the linker.

If you don't want to reinstall, go you opt for cross-compile.

cargo clean
export GOOS="darwin"
export GOARCH="arm64"
export CGO_ENABLED=1

But we would installing go version that match your architecture makes more sense.
