Multitest is a design to simulate a blockchain environment in pure Rust. This allows us to run unit tests that involve contract -> contract, and contract -> bank interactions. This is not intended to be a full blockchain app but to simulate the Cosmos SDK x/wasm module close enough to gain confidence in multi-contract deployements before testing them on a live blockchain.
To understand the design of this module, please refer to
Appimplementation working with customized exec and query messages. Outside of
Appimplementation to make type elision better.
