Example

use ceres_runtime::Runtime;

#[test]
fn test_flipper() {
    let mut rt = Runtime::from_contract(include_bytes!("../flipper.contract"))
        .expect("Create runtime failed");

    rt.deploy("default", &[]).expect("Deploy failed");
    assert_eq!(&rt.call("get", &[]).expect("Call contract failed"), &[0]);

    rt.deploy("new", &["true"]).expect("Deploy failed");
    assert_eq!(&rt.call("get", &[]).expect("Call contract failed"), &[1]);

    rt.call("flip", &[]).expect("Call contract failed");
    assert_eq!(&rt.call("get", &[]).expect("Call contract failed"), &[0]);
