# Cosm-Orc
[](https://crates.io/crates/cosm-orc) [](https://docs.rs/cosm-orc)
Rust Cosmwasm smart contract integration testing and gas profiling library.
Store, instantiate, execute, and query [Cosmwasm](https://github.com/CosmWasm/cosmwasm) smart contracts against a configured [Cosmos](https://github.com/cosmos/cosmos-sdk) based chain.
Optionally, profile gas usage of the smart contract operations.
If you need a more general Cosmos SDK client library try [cosm-tome](https://github.com/de-husk/cosm-tome), which we use here under the hood.
Potential uses:
* Integration tests
* Deployments / Bootstrapping environments
* Gas profiling
* Realistic adversarial testing
This project is not intended to be used for mainnet.
## Quick Start
```rust
// juno_local.yaml has the `cw20_base` code_id already stored
// If the smart contract has not been stored on the chain yet use: `cosm_orc::store_contracts()`
let mut cosm_orc = CosmOrc::new(Config::from_yaml("./example-configs/juno_local.yaml")?, false)?;
let key = SigningKey {
name: "validator".to_string(),
key: Key::Mnemonic("word1 word2 ...".to_string()),
};
cosm_orc.instantiate(
"cw20_base",
"meme_token_test",
&InstantiateMsg {
name: "Meme Token".to_string(),
symbol: "MEME".to_string(),
decimals: 6,
initial_balances: vec![],
mint: None,
marketing: None,
},
&key,
None,
vec![]
)?;
let res = cosm_orc.query(
"cw20_base",
&QueryMsg::TokenInfo {},
)?;
let res: TokenInfoResponse = res.data()?;
```
See [here](https://github.com/de-husk/cosm-orc-examples) for example usages.
## Optimize and Store Contracts
If `config.yaml` doesn't have the pre-stored contract code ids, you can call `optimize_contracts()` and `store_contracts()`:
```rust
let mut cosm_orc = CosmOrc::new(Config::from_yaml("./example-configs/juno_local.yaml")?, false)?;
let key = SigningKey {
name: "validator".to_string(),
key: Key::Mnemonic("word1 word2 ...".to_string()),
};
// Build + optimize all smart contracts in current workspace
// This will save the optimized wasm files in `./artifacts`
cosm_orc.optimize_contracts("./Cargo.toml")?;
// NOTE: currently cosm-orc is expecting a wasm filed called: `cw20_base.wasm`
// to be in `/artifacts`, since `cw20_base` is used as the contract name in the instantiate()/query() calls below:
cosm_orc.store_contracts("./artifacts", &key, None)?;
cosm_orc.instantiate(
"cw20_base",
"meme_token_test",
&InstantiateMsg {
name: "Meme Token".to_string(),
symbol: "MEME".to_string(),
decimals: 6,
initial_balances: vec![],
mint: None,
marketing: None,
},
&key,
None,
vec![]
)?;
let res = cosm_orc.query(
"cw20_base",
&QueryMsg::TokenInfo {},
)?;
let res: TokenInfoResponse = res.data()?;
```
## Gas Profiling
```rust
let mut cosm_orc = CosmOrc::new(Config::from_yaml("config.yaml")?, true)?;
cosm_orc.instantiate(
"cw20_base",
"meme_token_test",
&InstantiateMsg {
name: "Meme Token".to_string(),
symbol: "MEME".to_string(),
decimals: 6,
initial_balances: vec![],
mint: None,
marketing: None,
},
&key,
None,
vec![]
)?;
let reports = cosm_orc.gas_profiler_report();
```
### Gas Report Github Action
Use the [cosm-orc-github-action](https://github.com/de-husk/cosm-orc-gas-diff-action) to view the cosm-orc gas usage as a PR comment.
Github action also supports showing the diff between 2 different reports.
