Personally, I do not see a need for testing unless and until I'm symptomatic. Since Im retired and have been in sort of a self-imposed quarantine and there is no real treatment for this, I just don't see a need to be tested. I regularly give blood to the Red Cross and they are now (currently) testing for antibodies. I've had two donations show up negative for antibodies so I'm pretty sure I have not had covid. If I deploy with the Red Cross I may need to get tested at the start and end of the deployment and Im ok with that.
