1. A method of testing a wireless device for beam forming performance, comprising:
performing pretesting of the wireless device to determine a set of valid test orientations, wherein a corresponding valid test orientation of the set of valid test orientations is based at least in part on a testing performance reliability associated with a corresponding beam generated by the wireless device during the pretesting;
determining measurements of communication performance of the wireless device at one or more angular orientations of the wireless device with respect to an antenna within a test chamber, wherein each angular orientation of the one or more angular orientations corresponds to a valid test orientation of the set of valid test orientations; and
determining whether the wireless device satisfies beam forming performance requirements by comparing the measurements of communication performance to one or more threshold criteria.
