To ensure that we don't accidentally break the above, we should add a integration test for this. We don't show the code here for space reasons, but you can find it [on Github][stack overflow test]. The idea is to do a `serial_println!("ok");` from the double fault handler to ensure that it is called. The rest of the file is is very similar to our `main.rs`.
