Morphology

attest = test (opaque) = at + test

Although the form can be analysed as 'at-' + 'test', the meaning 'to bear witness or formally confirm' is a formal/borrowed sense not transparently derived from the everyday meaning of 'test' for most learners.

Etymology

Attest comes from the Latin parts ad- 'to' and testari 'to witness', and it shares the same root as test and testify. So to attest something is to officially 'witness' or confirm that it is true.
