T-test and robustness

Dear colleagues,

I remember I read, in the past, somewhere, that the student test was
quite robust regarding violations of the normality assumption but
cannot remember where I read this. So it is still relevant to use it
even with 'small' sample sizes (not too small however, maybe 15 or 20
in groups to be compared).

Does one has an opinion on the matter and/or could provide me with a
reference ?

Regards,

Catherine.
