Wolff, who was confirmed by the team in "an enhanced role as test driver" in late November, is scheduled to take part in two FP1 sessions this season and two tests.
Earlier today, the team took to Twitter to reveal that the 32-year-old "will drive the FW37 for one day of the first Barcelona pre-season test".
Following last year's Spanish Grand Prix, Wolff took part in the official test, finishing fifth overall, 0.7s ahead of Sebastian Vettel.
At Silverstone she became the first woman to participate in a Grand Prix weekend since Giovanna Amati in 1992. Unfortunately her track time was limited when she suffered an engine issue after just one lap.
Two weeks later she participated in FP1 at Hockenheim, and whilst this session also began with a car issue she was subsequently able to get out and complete some serious mileage ending the day just a few hundredths of a second down on teammate Felipe Massa.
Meanwhile, the Grove outfit has announced a new technical IT partnership with Dtex Systems, the global security software provider, that will see Dtex introduce its auditing software across Williams' range of business operations.
