Williams has announced that Susie Wolff and Daniel Juncadella will join Pastor Maldonado in this week's young driver test at Silverstone.
After weeks of speculation about its plans for the test, Williams confirmed that Wolff will get her first proper run in a Formula 1 car, having completed an aero test in this year's FW35 at Idiada earlier this year.
Speaking about her opportunity, Wolff said: "It's a fantastic opportunity for me, so now it is up to me to prepare myself the best that I can for the day.
"It's going to be a big challenge but the most important thing is to do a solid and consistent job and to give good feedback to the team to be able to prove I am at the level to compete on a day such as this."
Wolff will run on the final day of the test on Friday, with Juncadella driving on the opening day on Wednesday. Maldonado will run on Thursday to evaluate the new Pirelli tires.
