e064254
The scripted suite, measured over the wider list
The headline figures catch up with the engine: the CSS reference tests at
9458 of 14,616, and the scripted tests at 129,609 of 144,207 over the
twenty-six directories the suite now covers rather than the seventeen it
named.
That widening is worth its own paragraph here, because the number moved for
two different reasons and a reader deserves to know which. Nine directories
were added deliberately: a score measured only where the engine had already
built something measures the engine's own work, not the web, and the honest
figure over the wider list began at 78.7 per cent.
