On board the ISS, the crew - American Anne McClain, Russian Oleg Kononenko, and Canadian David Saint-Jacques - were scheduled to carry out a welcoming ceremony.
The dummy in the capsule - which SpaceX's Hans Koenigsmann prefers to call a "smartie" - is fitted with monitors to test the forces to which future astronauts will be subjected on take-off and when they return to the Earth's atmosphere and then splash down in the Atlantic, slowed down by giant parachutes.
Routine crew missions to the space station could start later this year.
The mission also marks a significant step toward to the return of human launches to the space station on a US -built spacecraft from USA soil since 2011.
SpaceX's new crew capsule arrived at the International Space Station on Sunday, acing its second milestone in just over a day.
The Crew Dragon is created to stay docked to station for up to 210 days, although the spacecraft used for this flight test will remain docked to the space station only five days, departing Friday, March 8, NASA said.
"Everything looks great", United States astronaut Anne McClain, who oversaw events from the station's big bay window, or Cupola.told Mission Control after looking inside Crew Dragon through a hatch window just before the crew entered.
No astronauts have been launched to space from American soil since that final shuttle flight in 2011, with the journey to orbit being handled by Russian Soyuz craft instead.

"I know you heard the applause and all the clapping that went along with the accomplishment today and so it's just one more milestone that gets us ready for our flight coming up here". Around 0900 GMT, Dragon was 3,000 meters away, NASA said.
Ripley was joined in the ship's maiden flight by Little Earth - a plush toy which looks like the Earth with arms and legs. After remaining in this position for approximately 10 minutes, Dragon will be cleared to proceed to 20 meters for another brief hold, followed by docking to the ISS.
NASA says that Boeing's CST-100 Starliner continues to undergo testing in preparation for its Orbital Flight Test, slated for no earlier than April.
