1. A wind turbine rotor blade load emulator arrangement comprising:
a support unit constructed to support a rotor blade during a fatigue test procedure, wherein a root end of the rotor blade is mounted to the support unit during the fatigue test procedure;
an exciter configured to effect cyclic deflection of the rotor blade during a fatigue test procedure;
a number of load emulator fittings, wherein a load emulator fitting is realized for attaching to the rotor blade; and
a stiffness augmentation assembly for mounting to the rotor blade over a mounting length, which stiffness augmentation assembly is realized to increase the stiffness of the rotor blade in the mounting length.
