Pascal Wehrlein will receive further outings for both Force India and Mercedes at next week's post-race test in Austria.
Wehrlein drove for both squads during pre-season testing and received another day in the Mercedes W06 Hybrid in Spain, though missed out on running for Force India due to illness.
Wehrlein will test for Force India on Tuesday before moving to Mercedes on Wednesday, the squads confirmed to F1Zone.net.
Nico Rosberg will drive for Mercedes on the opening day of running at the Red Bull Ring.
Wehrlein's outing for Force India will be the first in its 2015 car, the VJM08, as he only sampled the team's 2014 machine during pre-season running.
