 ### Testing
 Run `cargo build --release --target=wasm32-unknown-unknown`, then the contract will build in `target/wasm32-unknown-unknown/release/*.wasm`
-Besides, you can run deploy the ewasm contract on [WasmEdge](https://github.com/WasmEdge/WasmEdge) and run tests on it with `cargo test`.

 ### Debugging
 Furthermore, you can debug your ewasm contract with debug macro `sewup::ewasm_dbg!`, and run the contract with message output by `cargo test -- --nocapture`.
