+use std::process::Command;
+use std::time::{Duration, Instant};
+use wait_timeout::ChildExt;
+
+fn main() -> io::Result<()> {
+    let mut child = Command::new("sleep").arg("100").spawn()?;
+
+    let start = Instant::now();
+    assert!(child.wait_timeout(Duration::from_millis(100))?.is_none());
+    assert!(start.elapsed() > Duration::from_millis(100));
+
+    child.kill()?;
+
+    let start = Instant::now();
+    assert!(child.wait_timeout(Duration::from_millis(100))?.is_some());
+    assert!(start.elapsed() < Duration::from_millis(100));
+
+    Ok(())
