Massa will drive the new Ferrari for the first three days at Jerez, which runs from February 5-8, with de la Rosa getting his maiden run for the Italian outfit on the final day.
Alonso meanwhile will use that week to work on his physical condition, before he drives the Ferrari for the first three days of the Barcelona test that runs from February 19. Massa will then drive on the final day of that week.
For the final test that runs at Barcelona from February 28 to March 3, Alonso and Massa will split the driving duties.
On Thursday (28) and Saturday (March 2) of that test, Massa will drive, while Alonso will do the other two days.
