The company said in a statement the Friday flight -- lasting 1 hour, 49 minutes -- was "uneventful," and "straightforward," Britain's Guardian newspaper reported.
The statement said Boeing expects to deliver data from the test to the U.S. Federal Aviation Administration "in the coming days. Once we deliver the materials we stand ready to reply to additional requests and continue in dialog with the FAA to ensure we have met all of their expectations," the company said.
The 787 Dreamliners were grounded around the world after two fires in January that originated with the electrical systems at or near the jet's lithium-ion batteries.
One incident occurred on a runway of a plane that was being serviced. There were no passengers onboard.
In the other incident, the jet made a successful emergency landing.
Boeing has sold 50 jets and has orders for hundreds more.
