Mick Schumacher, son of seven-time champion Michael, will make his Formula 1 test debut for Ferrari on 2 April.
The 20-year-old German, who signed up to the Ferrari driver academy over the winter, will drive for Ferrari in Bahrain on one day and the affiliated Alfa Romeo team the next.
But he did drive his father’s 1994 Benetton at Spa in a demonstration run two years ago.
Schumacher’s test debut will cap a busy week as he is also due to make his Formula 2 debut at Bahrain this weekend.
After his two F2 races, Schumacher will spend Monday with Ferrari to work on preparations for his first run in the SF90 on Tuesday.
Schumacher was signed up as a member of the Ferrari Driver Academy over the winter following his European Formula 3 championship success.
Michael Schumacher won five of his record-breaking tally of world titles for Ferrari, and the vast majority of his all-time record 91 Grand Prix victories.
The 50-year-old, who retired from F1 for a second time at the end of 2012, has not been seen in public since suffering severe brain injuries in a skiing accident in December 2013.
His family has declined to reveal details of his condition, saying they believe he would prefer it to remain confidential.
