What is the test for making an application for habeas corpus?

"To satisfy the initial burden of pleading adequate grounds for relief, an application for habeas corpus must be made by petition . . . . [Citation.] The petition should both (i) state fully and with particularity the facts on which relief is sought [citations], as well as (ii) include copies of reasonably available documentary evidence supporting the claim, including pertinent portions of trial transcripts and affidavits or declarations. [Citation.] 'Conclusory allegations made without any explanation of the basis for the allegations do not warrant relief, let alone an evidentiary hearing.' [Citation.] We presume the regularity of proceedings that resulted in a final judgment . . . ." (People v. Duvall (1995) 9 Cal.4th 464, 474-475.)
