Tokio Async/Await Test
This is a simple crate that provides a procedural macro similar to #[test]
that will run the test as a single future on a tokio runtime.
Usage
First, you must be on nightly rust as of 12-02-2018
. Add the crate to your Cargo.toml
.
[dependencies]
tokio-async-await-test = { git = "https://github.com/LucioFranco/tokio-async-await-test" }
This will give you the crate but you will also need to make sure that you also have futures-preview
and tokio
as dependencies like so.
tokio = { version = "0.1", features = ["async-await-preview"] }
futures-preview = { version = "0.3.0-alpha.10", features = ["tokio-compat"] }
Once, you have all these dependencies you can then use the attribute like so.
#![feature(pin, async_await, await_macro, futures_api)]
extern crate futures;
extern crate tokio;
extern crate tokio_async_await_test;
use tokio_async_await_test::async_test;
#[async_test]
async fn basic() {
await!(example_async_fn());
}
This will spin up a tokio runtime and block on the basic
function. This generally expands to look like this. Where fut
is the test future you are running.
#[test]
fn basic() {
// -- snip --
let mut rt = Runtime::new().unwrap();
rt.block_on(fut().unit_error().boxed().compat()).unwrap();
}
You can also use a current thread runtime by importing use tokio_async_await_test::async_current_thread_test;
.
