Me and Flight Attendant 4 noticed stronger fuel exhaust fumes [than] we normally smell (or that's what we think it could have been) at some point between pushing back and idling waiting for takeoff.  We had performed our safety checks and were strapped into our jumpseats. I did not see any haze or smoke and I did not have a visual on the cabin in the Flight Attendant 4 aft facing jumpseat; but Flight Attendant 4 did not report that he saw any smoke or haze. While we both discussed the worse than usual exhaust fume Flight Attendant 4 complained of a headache and I felt 'out of it.' Brain fog is the best way I can describe it; but I had very familiar and muscle-memory kind of tasks to perform so we proceeded with service. After service; I told Flight Attendant 1 what we had experienced.  He called the Captain and reported the issue. Once we were deplaned in ZZZZ; a Mechanic came onboard but said he smelled nothing - more testing took place with all crew onboard. The deadheading Flight Attendant had left and our new Flight Attendant 4 was a part of this testing as well. After about an hour the crew were all feeling sick and stopped testing and left the plane. Most of nauseous and foggy.Place indicators of cabin air quality level throughout the cabin [at] all times clearly visible to both crew and passengers. [Have] oxygen masks for flight attendants at jump seats similar to those in the flight deck.  Much more awareness around air quality.  Objective measuring tools for mechanics at airports instead of just human sensory abilities. Medic at airports testing the flight crew immediately.
A319 Flight Attendant reported a fume event in the passenger cabin and associated health issues. At destination; medical testing was provided for flight attendant crew.
