Overview

The seam every test stubs.

A transport takes a fully-built request and returns a Response. It knows nothing about retries, authentication or error typing — all of which live in HttpClient — so a test double is four lines and still exercises the whole policy above it.

#inspect ⇒ Object

No key here, but the timeouts are the only state and printing them is useful. Defined anyway so the class never inherits a default #inspect if somebody adds an ivar later.
