Marco Melandri is testing with MV Agusta in Jerez as part of his 'development' deal with the Italian manufacturer ahead of the 2016 season.
The Italian, a former MotoGP runner-up and 19-time race winner at World Superbike level, has been absent from the spotlight since his ill-fated return to the premier class with Aprilia resulted in a split after just eight races.
Sitting out the remainder of the 2015 season, speculation was raised that Melandri could return to World Superbikes in 2016 with MV Agusta after being called up to help develop the F4RR, which will be prepared by former MotoGP outfit Forward Racing next season.
Though Melandri has refuted the suggestion he will be racing with the manufacturer in 2016, he is present in Jerez for the final World Superbike test of 2015 to give aid development.
As it stands, MV Agusta is expected to run just a single bike in WSBK for 2016, once more for Leon Camier, but hasn't ruled out the possibility off a second signing.
Also present in Jerez will be Althea Racing with its new BMW machinery, which will be ridden in 2016 by Jordi Torres and Markus Reiterberger.
