Features

All MultiTest features are listed in the table below.

The Default implementation column indicates whether the feature has a default implementation in MultiTest that simulates the functionality of the real blockchain as closely as possible. In cases where MultiTest does not have a default implementation for the feature, you can provide your own, using AppBuilder's function listed in AppBuilder constructor column. Names of MultiTest feature flags required to enable specific functionality are shown in the column Feature flag.

Starting point

Usually, a good starting point when using MultiTest is the following dependency configuration in Cargo.toml file:

[dependencies]cosmwasm-std = "2"[dev-dependencies]cw-multi-test = { version = "2", features = ["staking", "stargate", "cosmwasm_2_0"] }
