Can you say with certainty that if you perform a proper dry function test  on a firearm and the firearm passes the test, that it will fire?

No you cannot say that with certainty. A proper dry functions test in conjunction with a detailed stripping and cleaning of the weapon and your inspection of all the parts (particularly the firing pin) thus accessible will bring you much closer. However things could still occur that prevent a firearm from not functioning properly in a manner that you are unable to diagnose from a strip and assemble and a function test executed by the book.

Why do you ask?
 
A GPMG without a gas plug will still fire. Once.

But as has been said before, even if a function test works as intended, there may be other things that cause a weapon not to fire. A broken or missing firing pin, for example, wouldn't show up on a function test.
 
Once got a bolt for a C7 with a broken ejector, it fired but it really sucks when you get a stoppage every round. All the function tests worked properly though.
 
I function test is designed to prove the function of the fire control mechanism of the weapon. 

Will the safety work when in "safe"

Will the weapon fire in semi-auto when in "Repetition"

Will the weapon fire in full-auto when in "Automatic"

It will prove nothing in the chain that actually involves ammuntion, including the feeding, firing, or ejection process.

Hope that helps.
