The Briton completed the most laps of the day with 89, as he set the fourth fastest time at the Spanish circuit.
Speaking to reporters at the end of the day, di Resta said the team had achieved all it had hoped on the opening day of running for the VJM06.
"Forgetting what anyone else is doing, I would say we have carried on as we thought we would," di Resta said of the 2013 car.
"Today was quite positive. We got through the programme, got the data collection.
"This test is about correlation with the factory and understanding the car. That's our focus.
"It's nice to get the car out on track in anger, and there's nothing thrown up that we didn't think was there."
While uncertainty surrounds the identity of di Resta's team-mate for this year, he will share the driving duties with the team's simulator driver James Rossiter and 2012 test driver Jules Bianchi.
"James is very inexperienced in Formula 1 at the moment, but he's doing our simulator work so it's important for him to understand the correlation from the simulator to the track," he said.
"Jules has obviously done a lot with Ferrari in the past and a lot with us, and the team has decided to put him in the car.
"Ultimately it will be another opinion on the car, and that's useful for the engineers to work with.
"But it's not hampering my preparations at all. I've got my programme and that's what I'm focusing on."
