An emulation library to ease contract development and testing for hypermint.
This version supports hypermint v0.4.4.
First, please append following code to Cargo.toml in your project.
[dependencies]
hmcdk = { git = "https://github.com/bluele/hypermint", tag = "v0.4.4" }
[dev-dependencies]
hmemu = { git = "https://github.com/bluele/hmemu", branch = "develop" }Then, you write a test code for contract.
extern crate hmemu;
#[test]
fn contract_func_test() {
let args = vec!["1", "2"];
hmemu::exec_process_with_arguments(args, || {
contract_func().unwrap();
hmemu::commit_state()?;
let state = hmc::read_state("key".as_bytes());
assert!(state.is_ok());
assert_eq!("value".as_bytes().to_vec(), state.unwrap());
let ret = hmemu::get_return_value();
assert!(ret.is_ok());
assert_eq!("ok".to_string(), String::from_utf8(ret.unwrap()).unwrap());
let ev = hmemu::get_event("test-event", 0);
assert!(ev.is_ok());
assert_eq!("key".to_string(), String::from_utf8(ev.unwrap()).unwrap());
Ok(())
})
.unwrap();
}Finally, you can run test command.
// This is required to build `lib` directory. Please see `build.rs` for details.
