Module test_engine
Expand description
Deterministic in-process engine used by unit tests and --shots
headless renders. It loads no network content: every “page” is a flat
colour derived from a stable hash of the URL, with a darker header
band, so different URLs render visibly different frames and pixel
assertions stay byte-stable across runs.
All received commands are recorded and inspectable via
TestEngine::commands, which is what widget tests assert against.
