CosmWasm合约测试 (CosmWasm Contract Testing)

单元测试 (Unit Testing)

To make tests, specify:

要测试，要明确：

#[cfg(test)]

mod tests { ...

}

To run tests: cargo test

运行测试：cargo test

集成测试 (Integration Testing)

The cw-multi-test (https://docs.rs/cw-multi-test/latest/cw_multi_test/) package allows for integration tests.

cw-multi-test (https://docs.rs/cw-multi-test/latest/cw_multi_test/)包允许集成测试。

We can do the following steps: 我们可以执行以下步骤：

1. Initiate the testing setup, which may look like the following, where we use instantiate_contract()and then can use execute_contract() accordingly: 启动测试设置，可能如下所示，我们使用 instantiate_contract()，然后可以相应地使用 execute_contract()：

fn setup_test(
    app: &mut App<
        BankKeeper,
        MockApi,
        MockStorage,
        SeiModule,
        WasmKeeper<SeiMsg, SeiQueryWrapper>,
        FailingStaking,
        FailingDistribution,
    >,
) -> (Addr, Addr) {
    let example_contract_code = app.store_code(Box::new(
        ContractWrapper::new(
            example_crate::contract::execute,
            example_crate::contract::instantiate,
            example_crate::contract::query,
        )
        .with_reply(example_crate::contract::reply),
    ));

    let example_contract_addr = app
        .instantiate_contract(
            example_contract_code,
            Addr::unchecked(ADMIN),
            &example_crate::msg::InstantiateMsg {
                example_param: Uint64::new(100),
            },
            &[],
            "example",
            Some(ADMIN.to_string()),
        )
        .unwrap();

    app.execute_contract(
        Addr::unchecked(ADMIN),
        example_contract_addr.clone(),
        &ExampleExecuteMsg::ExampleCall {
            asset_denom: "usei".to_string(),
        },
        &[],
    )
    .unwrap();

    example_contract_addr
}

使用 Sei 链进行端到端测试 (End-to-end testing with Sei chain)

In order to do end-to-end testing, follow the previous steps to 1) launch the chain either locally or on devnet: https://docs.seinetwork.io/smart-contracts-and-local-development/set-up-a-local-network, and 2) deploy your contract: https://docs.seinetwork.io/smart-contracts-and-local-development/deploy-a-generic-contract. For an example contract that can be used for local testing see the following: https://github.com/sei-protocol/sei-cosmwasm

为了进行端到端测试，请按照前面的步骤 1) 在本地或 devnet 上启动链：https://docs.seinetwork.io/smart-contracts-and-local-development/set- up-a-local-network，以及 2) 部署你的合约：[https: //docs.seinetwork.io/smart-contracts-and-local-development/deploy-a-generic-contract](https://docs.seinetwork.io/smart-contracts-and-local-development/deploy-a -通用合同)。有关可用于本地测试的示例合约，请参见以下内容：https://github.com/sei-protocol/sei-cosmwasm

For debugging, such as if an order is unsuccessful, one can use a combination of tools on the contract side. Firstly, the Rust compiler can catch issues at compile time. Secondly, for any struct that implements the Debug trait then println! can be used. Lastly, logs can be added via deps.api.debug(err) on the contract side.

对于调试，如果订单不成功，可以使用合约端的工具组合。首先，Rust 编译器可以在编译时发现问题。其次，对于任何实现了 Debug 特性的 struct，都可以使用 println!。最后，可以通过合约端的 deps.api.debug(err) 添加日志。
