Rodolfo Gonzalez will drive the Caterham on the first day of next week's Formula 1 test at Mugello.
Gonzalez, who drives for Caterham's GP2 squad, had previously tested for the squad in the young driver sessions in 2010 and '11, when it was still known as Lotus.
The 25-year-old Venezuelan will be in the cockpit for the opening day on Tuesday, before race drivers Vitaly Petrov and Heikki Kovalainen take a day each.
"It will be my third time in an F1 car with this team and it will be another good chance for me to further my experience at the top level of global motorsport," said Gonzalez.
"I took part in the young driver tests in 2010 and 2011 with the team, so to be able to help their development programme mid-season is another good step in my career and something that I can take lessons from back into my GP2 season with Caterham Racing."
Caterham Group CEO Riad Asmat said Gonzalez had earned the chance with strong performances in previous tests.
"He did a good job for us when he took part in the young driver tests, and we expect him to work to the plans he is given, deliver what we ask him to on track, and provide the engineers with the sort of feedback someone with his experience should," said Asmat.
