Given the context of this test class, I think configuring the request with a timeout shouldn't be necessary. In general, we rarely use timeouts (hardcoded ones specifically) in our tests because these tests run on a variety of hosts (some of which are slow or are running too many tests concurrently) and thus there's no right value for the timeout and can lead to intermittent failures.
