"""tools/harness-safari.py [FRAGMENT] [TIMEOUT_S]
|
|
|
|
The loop harness in Safari (WebKit, the iPhone's engine: play() policy, read-only element volume, one audio session),
|
|
driven over WebDriver by safaridriver, in real time, over http from a temp server. Prints #diag once it says END.
|
|
Needs `safaridriver --enable` once (admin). Stdlib only.
|
|
|
|
Safari has no autoplay flag: the harness fragment gets a real click first (WebDriver clicks count as user activation),
|
|
so what runs is what a tapped phone runs.
