A bottom hole assembly (BHA) has a plug below a debris catcher and an optional telescoping joint. A cleaning tool is above the debris catcher with another cleaning tool further up the BHA that is designed to clean the riser that extends up from the BOP. The plug is spotted and released to commence the BOP cleaning and the riser cleaning. The cleaning tools can be reconfigured to allow through flow after the cleaning is done so that the rams can be closed around a drill collar and a pressure test take place. With the BHA above the BOP the rams can be closed against each other for another pressure test from above. In a variety of options for the method, the plug can be retrieved after released or left in the hole in the set position.
