Ducati was frustrated by rain at Jerez as it tried to get three days of running in ahead of next month's first official MotoGP test of the year at Sepang.
Test riders Michele Pirro and Franco Battaini were present at the Spanish track from Saturday through to Monday, but managed little mileage until the final day.
New team boss Bernhard Gobmeier was present at the track for the first time, and said Ducati had achieved as much as it could in the circumstances.
"Unfortunately we had some bad luck with the weather, and for two days we were able to do almost nothing. It rained almost the whole time," Gobmeier said.
"Today we squeezed three days of work into about five hours, which obviously required skipping some of the steps we had planned. Anyway, some interesting and positive results emerged, in terms of both the chassis and electronic strategies that we tried."
Gobmeier added that the mood at Ducati was buoyant even though the test was difficult.
"I was very pleased to see how concentrated the guys on the test team worked," he said. "Everybody was very motivated."
