Di Resta has been competing in the DTM touring car championship
Scotland's Paul di Resta remains on course to land the Force India reserve role for 2010.
The West Lothian driver, 23, has shown up very well during Formula 1's young driver test at Jerez in Spain.
He finished well ahead of team rival, American JR Hildebrand, placing second, fastest twice and fourth fastest from 12 over the three-day event.
Di Resta, the cousin of IndyCar Series champion Dario Franchitti, won the Formula Three Euroseries in 2006.
"It's a great opportunity and something I have waited a very long time to get a hold of," Di Resta told BBC Scotland earlier this week. "Who knows what the future holds, but my aim is to get into Formula 1."
The Scot began his career in karting before moving into British Formula Renault and then the Formula Three Euroseries, beating present F1 Red Bull driver Sebastian Vettel to the title three years ago.
The Scot moved to the Deutsche Tourenwagen Masters (DTM) championship in 2007 and has previously been linked with a move to F1 with McLaren Mercedes and Virgin Racing.
Force India, who finished ninth in the F1 championship in the season just past, have decided to retain Adrian Sutil and Vitantonio Liuzzi as their drivers for 2010.
"It is a very exciting time and I have to be realistic and productive over these testing days," said Di Resta, who began racing go-karts from the age of three.
"It is very difficult to predict anything. Force India are giving me a chance to drive the car and we are looking to try to bond a relationship that will work for many years to come.
Becoming a test driver would bring Di Resta within touching distance of following fellow Euroseries graduates Vettel, Nico Rosberg and Lewis Hamilton into an F1 race car.
