What is the test for stipulating there is a factual basis for admitting to a crime?

^2. The court took a bare stipulation there was a factual basis to the admission. "If the trial court inquires of defense counsel regarding the factual basis, it should request that defense counsel stipulate to a particular document that provides an adequate factual basis, such as a complaint, police report, preliminary hearing transcript, probation report, grand jury transcript, or written plea agreement." (People v. Holmes (2004) 32 Cal.4th 432, 444.)
