How much data does Speedtest app use on mobile?

I had about only 50mb left from my 1gb internet bundle on my iphone 5, but after using speedtest app for a few minutes, it all gone! I know 50mb is very little but it's fine for using whatsapp.

So I wanted to know how much data does speedtest consume?

Just used it on Sprint, cost me 13.3MB of data.
