1. A method for testing of a door operator, said door operator being configured to via a mechanism move at least one door leaf between a first position and a second position, the door operator comprising a first drive unit configured to move the door leaf into said first position, said door operator further comprising a control unit connected to a sensor, the method comprising:
initiating simulated powerless mode, wherein the first drive unit powers a movement of the door leaf into the first position and wherein the control unit remains electrically connected,
measuring by the sensor how the door operator moves the mechanism and the door leaf to the first position, and
comparing measured values of the movement of the mechanism by means of the control unit with reference values for the movement of the mechanism and the door leaf.
