French youngster Pierre Gasly will make his Formula 1 test debut at next month's running following the Spanish Grand Prix.
Red Bull backed Gasly, 19, will race in GP2 with DAMS this season, having finished as runner-up to Carlos Sainz Jr in last year's Formula Renault 3.5 series.
Under 2015 regulations, teams must allocate two of the four in-season test days to young drivers; Toro Rosso did not specify on which day Gasly will drive.
Formula 1's other in-season test will take place after the Austrian Grand Prix in June.
