This is repeating TestHandleEvent with only a few differences. We could use a testing table so that we could test [0-2] interceptors in a bit less verbose way. This seems fine though.

Yeah long term, I want to extract the common bits out into a couple of helper methods that create the required resources, and the clients (like we do in the reconciler tests in pipeline). For this PR though, I wanted to keep the non-fix changes to a minimum

This still runs the risk of panicking if request or Body is nil. We probably want to have checks here to handle gracefully.

testing this is going to require us to refactor our tests a bit...gonna make this a new commit in this PR!
fixed! PTAL
We were passing the original request where the body had been drained to the first interceptor meaning that the body to the first interceptor in the chain was always empty. Further, we were using the `GetBody` which can sometimes be empty leading to a panic. fixes tektoncd#355 Signed-off-by: Dibyo Mukherjee <[email protected]>

I don't feel too strongly about this, but should we be consistent with the webhook handler and default to []byte{}?

Sure, we'd have to do it the other way around though since makeCelEnv errors out if you pass it []byte{}
