Susie Wolff will get her first experience of Williams' new 2015 Formula One car during the second pre-season test in Spain in February.
Wolff's drive comes as part of her expanded official test driver role with the team, which will also see her contest two FP1 sessions over the course of the season.
Williams confirmed that Wolff will drive the Mercedes-powered FW37 on the first day of the Barcelona test, which takes place at the Circuit de Barcelona-Catalunya on February 19-22.
Wolff became the first female to drive in a Grand Prix event for two decades when she took part in FP1 in Britain and Germany for Williams during the 2014 campaign.
The team meanwhile enjoyed a breakthrough season, claiming the only non-Mercedes pole of the year and nine podiums in total to finish third in the constructors' championship - their highest finish in more than a decade.
