testifier
One who declares
A testifier is someone who testifies—gives testimony in court, before a committee, or in any formal proceeding.
The word emphasizes the role or identity of the person giving evidence: The testifier seemed nervous under cross-examination.
Less common than witness, which covers the same ground.
