Why benzaldehyde does not give fehlings test..?

Fehiling's solution is an alkaline solution of copper sulphate containing sodium potassium tartarate.

When Fehling's solution is added to a aldehyde, it gives out a red precipitate. This red precipitate is nothing but cupprous oxide.
Normally, when Fehling's solution is added to say, acetaldehyde, it gives acetic acid and cupprous oxide.

CH3-CHO + 2CuO -----------> CH3-COOH + Cu2O

But when benzaldehyde is added, it rapidly converts into benzyl alcohol and sodium benzoate because of the presence of alkali(Cannizzro's Reaction) . Here, there is no formation of cupprous oxide to give out a red precipitate.
