South Korea's peak testing rate per capita is lower than the US's per capita testing rate now or at any point in the last month or so. Same when comparing to many of the European countries. Their testing was fairly substantial compared to what other countries were doing a few months ago, but it wasn't "mass testing" in the sense that the US press and experts are currently advocating. (Most of the tests were focused on Shincheonji members, even though infections almost certainly weren't - they just made an easy target). It was, however, enough to indicate that testing and contact tracing was missing a substantial chunk of infections which were spreading within the community. Somehow they managed to stamp those out by tightening social distancing measures without a full lockdown or mass testing, and there's no good explanation for why this worked.
