When Hydrochloric acid reacts with an active metal (like zinc), we observe that gas filled bubbles are formed on the surface of the metal. ... Then, bring a burning candle near the gas filled soap bubble. If the gas present in bubble burns with a 'pop' sound, then its hydrogen gas.

Answer:
Hydrogen gas is liberated whenever a metal reacts with an acid.So if HCl will react with an active metal then also Hydrogen would be liberated.So to test its presence you will have to bring a matchstick near it and if the matchstick burns with a pop sound and a pale blue flame then the gas present is Hydrogen.
