An utility package to test susydev-jsonrpc-core based projects.

use susydev_jsonrpc_derive::rpc;
use susydev_jsonrpc_test as test;

use susydev_jsonrpc_core::{Result, Error, IoHandler};

#[rpc]
pub trait Test {
	#[rpc(name = "rpc_some_method")]
       fn some_method(&self, _: u64) -> Result<u64>;
}


struct Dummy;
impl Test for Dummy {
     fn some_method(&self, x: u64) -> Result<u64> {
    Ok(x * 2)
     }
}

fn main() {
  // Initialize new instance of test environment
  let rpc = test::Rpc::new(Dummy.to_delegate());

  // make a request and verify the response as a pretty-printed string
  assert_eq!(rpc.request("rpc_some_method", &[5]), r#"10"#);

  // You can also test RPC created without macros:
  let rpc = {
    let mut io = IoHandler::new();
    io.add_method("rpc_test_method", |_| {
   	  Err(Error::internal_error())
   	});
    test::Rpc::from(io)
  };

  assert_eq!(rpc.request("rpc_test_method", &()), r#"{
  "code": -32603,
  "message": "Internal error"
}"#);
}
