Usage: {Test}, {Trial}. Trial is the wider term; test is a
searching and decisive trial. It is derived from the
Latin testa (earthen pot), which term was early
applied to the fining pot, or crucible, in which
metals are melted for trial and refinement. Hence the
peculiar force of the word, as indicating a trial or
criterion of the most decisive kind.

I leave him to your gracious acceptance, whose
trial shall better publish his commediation.
--Shak.

Thy virtue, prince, has stood the test of
fortune,
Like purest gold, that tortured in the furnace,
Comes out more bright, and brings forth all its
weight. --Addison.
