Test Tube X

test-tube is a generic library by Osmosis for building testing environments for CosmWasm 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 the Cosmos SDK.

test-tube-x is a fork of test-tube by Persistence made using newer versions of Cosmos SDK (v47). It can be used by anyone to create a testing environments by anyone using the following defaults:

  • Cosmos SDK v47
  • Persistence SDK v2
  • Cosmwasm v1.4

test-tube-x is currently used to build persistence-test-tube.

You can refer to Osmosis Test tube docs to get more information on how to build upon test-tube or test-tube-x.

Features

  • Test your CosmWasm smart contracts using Rust without the need to write Go code or learn Go
  • Test against the actual Cosmos SDK chain's logic
  • Build testing environments for any Cosmos SDK-based chain

Why don't just use cw-multi-test?

You might want to just use cw-multi-test if your contract does not interact with chain's custom module. 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 test-tube.
