+
+I have been writing a [lot of](https://github.com/reiseburo/hotdog) [Rust lately](https://github.com/rtyler/otto)
+and as a consequence I have had to get a _lot_ better at writing unit tests. As
+if testing along weren't tricky enough, almost everything I am writing takes
+advantage of `async`/`await` and is running on top of the
+[async-std](https://async.rs/) runtime.
+
+Testing `async` functions with `async-std` is actually so easy it's no wonder
+nothing showed up in my first search engine queries! Rather than using
+`#[test]` use the `#[async_std::test]` notation and convert the test function
+to an async function, for example:
+
+```rust
+async fn simple_method() -> boolean {
+    true
+}
+
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[async_std::test]
+    async fn test_simple_case() {
+        let result = simple_method().await;
+        assert!(result);
+    }
+}
+```
+
+That was easy™
+
+
+Another option which also worked out just fine was to utilize [smol](https://github.com/stjepang/smol) as in `dev-dependencies` to run something like:
+
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[test]
+    fn test_simple_case() {
+        let result = smol::run(simple_method());
+        assert!(result);
+    }
+}
+```
