I'm not sure if it's an official test, but you could take a lit match and put it in the test tube (keeping the test tube right side up). If the test tube does contain carbon dioxide the match would be smothered since the carbon dioxide prevents oxygen from reaching the match.
to see if a gas given off is carbon dioxide you can trap gas in a test tube light a splint and place in tube if flame goes out then it is Carbon Dioxide
The splint test is to test for the presence of oxygen. You light a small piece of wood (the splint), then blow it out. The end of the wood will still glow. If you put the glowing splint into a test tube with oxygen, it will relight. It you put the glowing splint into a test tube with carbon dioxide, it will stop glowing. A better test for carbon dioxide is to bubble it through a solution of limewater.
Carbon Dioxide can be poured because its density is higher than air which makes it sit lower. So if you take a test tube filled with carbon dioxide, then you can pour it just like a liquid.
when lime water react with carbon dioxide,it turns milky.So, we have to take some lime water in a test tube and exhale 2 -3 times to the test tube through a bend tube. It will turn milky and that's why our exhaled breath is carbon dioxide.

is carbon dioxide and or hydrogen in a clean empty test tube
By blowing into a test tube of bicarbonate of soda, this should turn cloudy if carbon dioxide is present
Testing for carbon dioxide step wise:- 1.Invert a test tube so that the open end is facing down. 2.Release the gas you want to test from its container into the test tube. Keep the test tube inverted so that the gas does not escape. 3.Light a splint with matches or a lighter. Place the lit end of the splint in the test tube. The splint will immediately extinguish if carbon dioxide is present in the gas. 4.Place moist blue litmus paper in the test tube. The litmus paper will turn red if carbon dioxide is present in the gas. 5.Place moist universal indicator paper in the test tube. The universal indicator paper will turn orange if carbon dioxide is present in the gas.

Carbon Dioxide (CO2)
Carbon dioxide1. Turns lime water (calcium hydroxide) milky2. A lit splint introduced to a test tube containing carbon dioxide should go outHydrogenA lit splint introduced to a test tube of hydrogen should go out with a distinct "pop"
