What is the test for compelled testimony in a criminal case?

"The Fifth Amendment to the United States Constitution states that '[n]o person . . . shall be compelled in any criminal case to be a witness against himself . . . .' The high court has made clear that the meaning of this language cannot be divorced from the historical practices at which it was aimed, namely, the brutal inquisitorial methods of ' "putting the accused upon his oath and compelling him to answer questions designed to uncover uncharged offenses, without evidence from another source." ' [Citations.] . . . [T]he amendment prohibits the direct or derivative criminal use against an individual of 'testimonial' communications of an incriminatory nature, obtained from the person under official compulsion." (People v. Low (2010) 49 Cal.4th 372, 389-390.)
