Its not tests we should be counting but the number of people seriously sick and work back from that. If we know that a percentage of the population will get hospitalised we can get a good estimate of the actual infected population. I think that the UK estimates that 10K people have it in the UK for example. (Number may be wrong, but they have produced an estimate based on the number of sick who tested positive) The UK is basically saying, currently, to not expect to be tested, that you will get it and that they have good knowledge of the levels. They are testing sick people in hospitals only. They also say that advice is likely to change each week.
