1. A method for testing a rotor blade component of a rotor blade for a wind power installation, the method comprising:
dividing a rotor blade component of the rotor blade into a plurality of rotor blade component segments, and
forming a plurality of cutouts in a connection interface at a connection end of a first rotor blade component segment of the plurality of rotor blade component segments,
wherein:
the connection interface has a thickness corresponding to at least 1.5 times a diameter of one or more of the plurality of cutouts, and/or
the connection interface has a thickness of at least 2 cm, and/or
the connection interface has a depth which corresponds to at least 2 times a diameter of one or more of the plurality of the cutouts, and/or
the connection interface has a depth of at least 10 cm.
