that's exactly what I was thinking. the whole EU can't stay on lockdown for months. so once the worst is over and the country wide lockdowns are done, if you wanna travel abroad, you should first go see your doc and get a test a few days before you travel and then get tested both at the airport of departure as well as on arrival. it's an expensive thing this, but if the goverment wants tourism to return and not being a risk, during the first few months it's the only way I can see it working really.
