Not providing context on the increase in testing is such a basic error, and has been so widespread, that it's revealing about the media's goals. It's more interested in telling plausibly-true stories ("narratives") that sound smart to its audience than in accuracy/truth per se.
That doesn't mean it's just making stuff up or engaging in fake news. On the contrary, the facts it relays are generally accurate in isolation. But the problems are in how facts are strung together and emphasized. Often there are sins of omission (e.g. no context on testing).
BTW, Trump has figured this out! By focusing on case counts, the media creates disincentives to do more testing because it makes the numbers look superficially worse. One reason (not the only one) why we're not pushing for testing as much as we should.
