At some point Spain had a ratio of around 0,4 of the total number of infected people against the total number of tests which, if we consider repeated tests, meant they could not test much more people than those ill ones. I am not saying this ratio gives the whole picture but it's for sure an interesting thing to see because it shows how much the countries test in relation to the virus spread in the population.
Strangely at the beginning there was a discussion here about Finland/Russia and the lack of testing in Russia. Now however Russia has 2nd highest total number of tests done after US (no numbers for China) and the ratio of infected people against the number of tests is very low 0,02 (0,08 for Germany; 0,13 for Italy; 0,18 for Sweden; 0,19 for US; 0,20 for Spain; 0,25 for UK... 0,72 for Algeria).
