Example Usage

// Example unit test:
// Uses provwasm mocks to test a resolve query against the provenance name module.

// ref: contracts/name/src/msg.rs

#[cw_serde]
#[derive(QueryResponses)]
pub enum QueryMsg {
    #[returns(provwasm_std::Name)]
    Resolve { name: String },
    #[returns(provwasm_std::Names)]
    Lookup { address: String },
}

// ref: contracts/name/src/contract.rs

#[test]
fn query_resolve() {
    // Create provenance mock deps with a single bound name.
    let mut deps = mock_dependencies(&[]);
    deps.querier
        .with_names(&[("a.pb", "tp1y0txdp3sqmxjvfdaa8hfvwcljl8ugcfv26uync", false)]);

    // Call the smart contract query function to resolve the address for our test name.
    let bin = query(
        deps.as_ref(),
        mock_env(),
        QueryMsg::Resolve {
            name: "a.pb".into(),
        },
    )
        .unwrap();

    // Ensure that we got the expected address.
    let rep: Name = from_binary(&bin).unwrap();
    assert_eq!(rep.address, "tp1y0txdp3sqmxjvfdaa8hfvwcljl8ugcfv26uync")
