A Ducati statement said the results of the sessions had been encouraging.
"During the three days, several new components on the chassis side of the 'laboratory' bike were tested successfully and everything went according to expectations," it said.
"In addition the riders tested some different electronic strategies and they also went according to plan, leaving the team satisfied with the outcome.
"The success of both of these solutions indicate that the Ducati Team is working in the right direction, in what is just the first phase of its development programme for this year."
Ducati had struggled during the first group test at Sepang earlier this month, ending up two seconds off the pace.
