Etymology
It is from testis “witness” and faciō “to make”, through ⟨-ficus⟩, with -or.[2][3][4] De Vaan explains ⟨testis⟩ from ⟨*tri-sth₂-i-⟩ “standing by as third”, cognate with Oscan ⟨trstus⟩ “witnesses”.[5]
Earliest recorded meaning
The OLD's earliest citation is Cicero, “to testify”.[2] Köbler dates Cicero 81–43 BC.[6]
Semantic evolution

In Ecclesiastical Latin it means to testify, bear witness, attest, charge, bring to light.[7] English testify (late 14th century) is from its family through Anglo-French.[8]
