safina-async-test

An async_test macro for running async fn tests.

It is part of safina, a safe async runtime.

Features

• Runs tests with safina_executor
• Each test gets its own executor with 2 threads for async tasks and 1 thread for blocking tasks.
• Also calls safina_timer::start_timer_thread before running the test
• forbid(unsafe_code)
• Lightweight dependencies
• Straightforward implementation

Limitations

• Building on stable requires once_cell crate which contains some unsafe code. This is necessary until std::lazy::OnceCell is stable.

Examples

use safina_async_test::async_test;

#[async_test]
async fn test1() {
    async_work().await.unwrap();
}

use safina_async_test::async_test;

// Make your test an `async fn`.
#[async_test]
async fn test2() {
    // You can `await`.
    async_work().await.unwrap();

    // You can spawn tasks which will run on
    // the executor.
    // These tasks stop when the test
    // function returns and drops the
    // executor.
    safina_executor::spawn(background_task());

    // You can run blocking code without
    // stalling other async tasks.
    let result = safina_executor::schedule_blocking(
        || blocking_work()
    ).async_recv().await.unwrap();
    assert_eq!(3, result.unwrap());

    // You can use timer functions.
    safina_timer::sleep_for(
        Duration::from_millis(10)).await;
    safina_timer::with_timeout(
        async_work(),
        Duration::from_millis(100)
    ).await.unwrap();
}
