WOW!  Now that's what I call testing!  (Wuhan's population is 11M)

ABC News, May 21 -

10:19 a.m.: Wuhan says it has conducted over 3 million coronavirus tests since last week
The Chinese city of Wuhan, ground zero of the coronavirus pandemic, conducted 887,321 nucleic acid tests for COVID-19 on Wednesday, up from 856,128 tests the previous day, according to the local health authority.
No confirmed cases of COVID-19 with symptoms were found during Wednesday's testing period; however, 28 new asymptomatic carriers were identified, according to daily reports published by the Wuhan Municipal Health Commission.

If the 28 positives were from the 887K tests, that's good for having few false positives.  (Ie, I'd like to know what the false positive & false negative rates are expected to be)
