Red Bull junior Pierre Gasly will drive for the Toro Rosso team in the post-Spanish Grand Prix Formula 1 test.
The 19-year-old Frenchman, who finished second behind Carlos Sainz in the Formula Renault 3.5 series last year, will get behind the wheel of the Renault-powered STR10 during the first in-season test of 2015 at Barcelona.
Gasly will compete in GP2 with DAMS this year, and the Toro Rosso outing will be his first in a Formula 1 car.
The test, the first of only two scheduled for this season, takes place after the Spanish Grand Prix on May 10.
Austria will host the second in-season test after the June 21 race.
