The Robolectric implementation of HttpURLConnection forwards to the JRE
implementation [1], which behaves differently to the Android one
available on devices and emulators. For these tests to be a realistic
test of the HTTP stack used in real playbacks we can't use Robolectric.

Robolectric uses the JRE HttpURLConnection [1], while real Android
devices and emulators use OkHttp to implement HttpURLConnection. This
can lead to important differences in behaviour, so it's better to use
instrumentation tests when specific HTTP behaviour is important.
