For more on marking an answer as the "Best Answer", please visit our FAQ.shammy is correct in that there is no single test for nitrogen. However, if you are talking about gases present in Earth's atmoshphere then you can rule out oxygen (glowing splint relights) and carbon dioxide (lime water turns milky) but then if burning magnesium continues to "burn" in the gas it must be nitrogen rather than one of the Noble gases.
I work in a lab where we analyze gas samples for inert gases. I am mostly interested in noble gases, but we can analyze a gas sample for nitrogen using gas chromatography. I'm not sure what type of column or detector we use ( I think it is a thermal conductivity detector). I can find out though if you are interested.
