Oxygen supports combustion so a good method of testing for oxygen is to take a glowing splint and place it in a sample of gas, if it re-ignites the gas is oxygen.
This is a simple but effective test for oxygen. There are sometimes confusions as the splint can create a pop very slightly on re-ignition, which sometimes is mistaken for hydrogen. A hydrogen pop is much more violent, sometimes enough to completely extinguish the splint
