I see there's a failure. Darn— on hapijs/shot#129 I almost specifically requested that someone try linking it to hapi and giving it a test run. It might be the case that it will work once #4095 lands.

So it looks like this fixes the test:

diff --git a/test/payload.js b/test/payload.js
index b776a44f..0379bdfa 100755
--- a/test/payload.js
+++ b/test/payload.js

         const responded = server.ext('onPostResponse');
 
-        server.inject({ method: 'POST', url: '/', payload: 'test', simulate: { close: true, end: false } });
+        server.inject({ method: 'POST', url: '/', payload: 'test', simulate: { close: true } });
         const request = await responded;

     it('handles aborted request', { retry: true }, async () => {

The issue is that after hapijs/shot#129, we no longer force a 'close' event to be emitted, and instead rely on Node to do it for us (which is why we need 'end' to be emitted).

The question is whether we want to update the test and move on with life, or fix/revert the behavior change in shot. The only issue with just updating the test here is that the shot release was a patch release and this is a subtle behavioral change.
