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

use susy_jsonrpc_test as test;

use susy_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)
     }
}

  // 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

  // You can also test RPC created without macros:

    io.add_method("rpc_test_method", |_| {
