Etymology

It is from testis “witness”.[2][1]

Earliest recorded meaning

The OLD's earliest citation is from Plautus, of calling someone to witness.[2] Köbler dates Plautus c. 250–184 BC.[3]

Semantic evolution

It meant to call a person or god to witness, as in Plautus, and in Cicero to declare solemnly, testify, and to make a will before witnesses.[2] In Ovid it meant to give evidence of something by one's actions or condition.[2]

It survives in Italian testare and Spanish testar “to make a will”.[1] Its participle testātus gave English testate in the late 15th century, and its noun testāmentum gave English testament in the late 13th century.[4]
