Pedro de la Rosa admits he had not expected to test for Ferrari during the 2013 Formula 1 pre-season.
The Spaniard joined Ferrari as a development driver earlier this month, with team boss Stefano Domenicali saying his primary task would be to assist with simulation work.
With Fernando Alonso not running at Jerez, Ferrari elected to hand de la Rosa his maiden run for the Italian outfit on February 8, the final day of the test.
"I am very happy to be able to test it and honestly I had not expected that," de la Rosa said.
"It's a unique opportunity to begin to understand how the car works and how I can help with the work in the simulator."
