Caterham Formula 1 test driver Alexander Rossi will drive for the outfit's GP2 team in both post-season tests this winter.
The American, who finished 11th in Formula Renault 3.5 driving for Arden Caterham this year, has two GP2 starts to his name, coming at last year's non-championship GP2 Final event in Abu Dhabi.
"It will be great to get back behind the wheel of the Caterham Racing GP2 car," said Rossi.
"I have already been working with the team at the new factory in Leafield where we ran through plans for the Barcelona [October 30-31] and Jerez [November 21-22] tests.
"I have experience with both Caterham Racing and the GP2 car from my outings last year and look forward to working closely with the whole team again at the forthcoming tests."
The team has announced that fellow FR3.5 racer Lucas Foresti will join Rossi for the first test.
Team manager Phill Spencer said: "We are all looking forward to the test next week and are delighted to have Alexander back with us.
"We are also looking forward to working with Lucas in his first GP2 test and hope we have a successful couple of days in Barcelona before we head to Jerez for our final outing of 2012."
