In bug 1864392, the urgency parameter set in our HTTP requests [1] is adjusted according to the value of the internal priority. This patch adds basic tests to verify some adjustments, and indirectly the internal priority, for scripts, images, styles, fonts and global fetches using different values of fetchpriority. This is done by introducing a Python handler [2] that serves different kind of content depending on the urgency parameter it receives and a WPT test that extracts the urgency from the served content.
