New York and L.A. County have indicated they will not test (some) cases that are expected to be COVID-19.  

Yes, not all likely infected patients are being tested. Here in Santa Clara County, my daughter had a high-risk exposure (60 minutes 2 feet away from another student who became symptomatic later that day and tested positive) and was put in 14-day quarantine within our house as a result. Her physician checked with the Dept. of Public Health and was told she would not be tested if she became symptomatic because she would be presumed infected. Presumably she would not be counted in the official totals if she became symptomatic, unless she needed hospitalization (fortunately, she just ended the 14 days asymptomatic). On the other hand, they said if my wife or I became symptomatic, we'd get tested.
